    [0001] The present invention relates to a method for closing boxes made of cardboard, corrugated board or similar sheet material, the section of which is divided by a section of the same. square or rectangular example, while reducing, where desirable, the height of these boxes to that of their contents. It also aims a machine for carrying out the various steps of this process.
    [0002] The technical field of the invention is that of packaging machines, cutting, manufacture or closure of packaging or manufacturing and implementation of methods and cushioning materials for such packaging. The present invention more particularly relates to the closure and height adjustment of boxes used for the preparation of single or multi-article orders and more generally of boxes used for packaging for shipment to customers or other recipients, various objects whose number and unit volume, and therefore also the overall volume, vary from one box to another. It is known that boxes of this type are formed by machines, from one or more blanks of rigid and foldable sheet material comprising different flaps and flaps secured together by gluing or by adhesive tape. Boxes are known which, after forming, are composed of five walls, either a square or rectangular bottom and a belt composed of four side walls assembled together at right angles, forming ridges. Boxes of this type are for example known as "American half-boxes", "trays" 25 or "bell cases". These boxes are usually, after filling, closed by a lid. Lids are also known which have four flaps that are folded and glued to the sides of the box. Lids are also known whose different shutters are previously shaped by nesting or gluing; these lids are inserted on the top of the box and secured to the box by gluing, stapling or by a metal or plastic tie. Boxes are still known which, after forming, are composed of a bottom and four side walls, like the previously described boxes, as well as four upper shutters. Each of these upper flaps is connected to one of the side walls of the box by a fold line. Boxes of this type are known as 35 "American Boxes". These boxes are, after filling, closed by folding the four upper flaps in the horizontal plane and maintaining these shutters by gluing, stapling or by a metal or plastic link. All the boxes described above, and, in general, most boxes used for packaging articles have the common feature of offering a constant volume after manufacture and closure. Various products are often used by the users or integrated in the machines for forming or closing boxes, to wedge the different objects previously packaged, the overall volume may vary from one box to another. This solution has many disadvantages. Indeed: - these wedging products are often expensive; - except when they are made from the same material as the packaging itself, they must necessarily be disconnected from the cardboard packaging before collection and possible recycling of the corresponding waste; secondly, the materials used are, in most cases, difficult to recycle; this collection and recycling are therefore complex and very expensive operations; their implementation is difficult and requires either complex automated machines or a large number of hours of labor; the cost of these operations is therefore high; the volume shipped, which is equal to the volume of the box manufactured, is, in most cases, considerably greater than the useful volume, which is equal to the volume of the objects arranged inside the box; this results in high transport costs for said boxes. Methods are also known which consist in reducing the height of the boxes in order to bring it closer to the height of the packaged products. In particular, the process of cutting and eliminating the upper part of the boxes situated above the upper level of the stack of objects housed in said box is known in order to reduce the height of the box to the useful height. . This method has drawbacks: cutting of the box is a delicate operation which involves the use of dangerous cutting tools subjected to wear, so that they must frequently be sharpened or replaced; - The automatic elimination of the upper part of the box cut is a difficult operation which also generates waste that must be collected and evacuated; the automation of this process therefore requires the production of complex machines. It is also known (EP-1,827,983) the method consisting in: performing a horizontal creasing (or grooving) on each of the 4 vertical walls of the box at an altitude corresponding substantially to that of the top of the stack of previously conditioned objects in said box; in each of the corners of the box, an oblique creasing (or grooving) having one end at the intersection between two of the horizontal creases and the other end being at the upper edge of the one of the side walls parallel to the length of the box, such that said oblique crease forms an angle substantially equal to 45 ° with the horizontal plane; - Then, finally, to fold the upper part of the two side walls parallel to the length of the box towards the center thereof, around said horizontal creasing, an angle substantially equal to 90 °, so that the one of them passes over the other during the folding phase in the case where the reduction in height is greater than half the width of the box, and at the same time folding the upper part of the two parallel side walls to the width of the box towards the center of the box, around said horizontal creasing, an angle substantially equal to 90 °. This method offers advantages over the previous method insofar as: it does not use cutting tools; it increases the resistance of the box, in particular its resistance to vertical compression. The two preceding methods make it possible to adjust the height of the box to the useful height but do not provide any solution for the closure of this box, so that this box must usually, after adjusting its height, be closed by a lid, as previously described.
    [0003] Also known is the method of cutting the four vertical edges of the box from the top of the box to an altitude corresponding substantially to that of the top of the stack of packaged objects and then to carry out a mining (or grooving) horizontally on each of the four side walls of the box at the same altitude, and finally to fold towards the inside of the box, around these horizontal creases and at an angle substantially equal to 90 °, the upper part of these four walls vertical. This method also makes it possible to adjust the height of the box by reducing it to the useful height. In addition, when the distance between the top of the stack of objects and the top of the box is equal to or greater than the half-width of the box, the upper part of one of the two side walls parallel to the length of the box the box must at least come into contact and possibly pass over the upper part of the second lateral wall parallel to the length of the box during the folding, so that they occupy, after complete folding, the whole of the upper surface of the box, possibly partially overlapping the center of said box. It is thus possible to simply close said box by providing means for maintaining said high parts in the folded position, for example by gluing.
    [0004] The latter method nevertheless also has drawbacks, such as: the cutting of the four vertical edges is a delicate operation which involves the use of dangerous cutting tools and subjected to wear; - These cuts generate dust that pollute the contents of the box. The problem thus posed consists in providing a means of reducing the height of a box, comprising a bottom and at least four side walls, as close as possible to the objects previously arranged in this box, and of simultaneously closing said box using for this purpose the material which constitutes said box, without adding additional material flank, and without the aid of any cutting tool. The solution to the problem is to provide a method for reducing the height of a box of foldable material, consisting of a bottom and at least four sidewalls, to the top level of the stack. objects previously arranged in said box, without removing a portion of material from said box, or using any cutting tool, but folding towards the center of said box the upper portions of said side walls, the method employed to realize the reduction in height of said box is remarkable in that: - the connections between said side walls are broken along the upper part of the vertical edges of a box made of foldable material, from the top of said side walls of this box; up to the level of the top of said stack of objects previously disposed in the latter, exerting a force directed towards the outside of said box, on the top part e, located above the level of the top of said stack of objects, at least two of said sidewalls; at the same time, towards the outside of said box, folds said upper portions on which said force is exerted; - Then all the upper parts of said side walls are folded inwardly of said box to bring them back into a substantially horizontal plane. In an advantageous embodiment of the method of the invention, after folding all said upper parts in a substantially horizontal plane, they completely close the opening of said box, and said high parts are maintained in said plane. horizontal, for example by gluing, strapping, applying adhesive tape, wrapping with a plastic film or a sheet of paper or any other equivalent means known per se or within the reach of those skilled in the art, which has the effect of maintaining closed said box. Advantageously, in order to exert said force on said side walls and to fold the upper parts of said side walls towards the outside of said box, said side walls are grasped in an area located between the top of said box and the level of the top of said stack. objects and preferably close to said vertical edges, for example by means of clamps each comprising at least two jaws, one acting on the outer face of the wall, the other acting on the inner face of the wall, and then pivoting each of said tongs and thus each of said top portions, about an axis of rotation substantially located on said side walls and at the top of said stack, towards the outside of said box. objects. In an advantageous embodiment, for gripping said side walls with the aid of said clamps, said box is previously moved towards all of said clamps, or the set of said clamps is moved towards said box, in a movement 15 perpendicular to the bottom of said box, and the corresponding movement is stopped when, for example with the aid of a sensor, a relative movement is detected between said clamps and a feeler, the shape and the general dimensions of which correspond substantially to those of said bottom, when said probe comes into contact with the top of said stack of objects. Advantageously, before folding the upper parts of said side walls towards the inside of said box, a creasing (also called grooving) is carried out at the level of the axis of rotation around which the folding must be carried out, located on said walls. side and at the top of said stack of objects. This grooving can be carried out over a reduced length, so as to constitute a folding primer, favoring the formation of a continuous fold line during the folding of the upper parts of the side walls which are no longer interconnected, direction of the center of the box, this folding primer can be performed when the clamps pinch the upper parts of the side walls of the box 1. In an advantageous embodiment, said box used, has cuts of reduced height and at most equal to the half-width of said box, made from the top of said box, at the vertical edges where are located the connections between said side walls. Advantageously, a bead of adhesive is deposited on the inner face of at least one of said high parts and said first unsized top portions are folded first, then said pre-bonded upper part is folded in such a way that said adhesive bead secures at least two of said upper portions together and maintains all of said upper portions in a substantially horizontal plane. In an advantageous embodiment, a bead of adhesive is deposited on the inner face of at least one of said upper parts and one or more bead of glue on the inner and / or outer face of the at least one other of said high parts and first folds said unsized high parts and then folds successively said upper portions previously glued such that said adhesive beads do not come into contact with said objects but solidarize several of said high parts together and maintain all said upper portions in a substantially horizontal plane. Advantageously, said adhesive beads are parallel to each other and the deposition of said adhesive beads is obtained by spraying glue from an adhesive reservoir using fixed gluing nozzles, during the movement of said box in one direction. parallel to said glue beads. The implementation of this method therefore makes it possible to reduce the height of the box to the useful height corresponding to the height of the stack of objects previously arranged in said box, and this reduction in height is obtained without removal of material or material. use of any cutting tool. The implementation of this method allows, on the other hand, to close said box without adding material but using only the material that constitutes said box. Thus, the invention provides an efficient, robust and economical method for reducing the volume of said box and closing it, because of the absence of cutting tool subject to wear and because it is not necessary to bring one or more additional material flanks. The advantages provided by the invention will be better understood from the following description which refers to the appended drawings, which illustrate, without any limiting character, a particular embodiment of the method according to the invention. FIG. 1 is an isometric view of an empty box that can be used for carrying out the method according to the invention. FIG. 2 is an isometric view, broken away, of a box of the same type filled with a number of objects of various shapes and sizes.

Figures 8 and 9 are two sectional views of the box and a machine part for carrying out the method according to the invention in two successive steps. Figure 10 is an isometric view of an empty box usable for carrying out the method according to the invention. Figures 11 and 12 are isometric views of the box at an intermediate stage of the process according to two different examples of implementation of this method. Figure 13 is a side view of the box and a machine part for carrying out the method according to the invention. Reference is made to the drawings to describe interesting, though in no way limitative, embodiments of the method according to the invention. In the following description, words such as "upper parts", "lower parts", "side walls", "horizontal" and "upper" are used, considering a resting box, through its bottom. , on a horizontal surface. These terms are, of course, not limiting in nature. Figure 1 shows a box 1 which is composed of a bottom and the side walls la, lb, lc and ld, connected to each other at right angles. Also shown in this figure are the vertical edges Zab, 2bc, 2cd and 2da which connect said sidewalls two by two. According to the illustrated example, the bottom has a rectangular shape, so that the box has the shape of a rectangular parallelepiped. We see that, according to this example, the side walls la and lc are parallel to the length of the box 1 and the side walls lb and ld are parallel to the width of said box 1. It is emphasized that the bottom and the side walls may have a different shape, for example a square shape or a general square or rectangular shape with cut corners. As indicated, this box 1 may be made of corrugated cardboard, compact cardboard or any other equivalent foldable sheet material having the necessary rigidity and known per se or within the reach of those skilled in the art. Figure 2 shows box 1, consisting of bottom 1c and side walls 1a, 1b, 1c and 1d, into which a number of objects 3, 4, 5, 6 and 7 of shapes and sizes have been introduced. varied. The number and size of objects can be any, as well as their storage in the box. The objects can in particular be stacked on top of one another if necessary. In order to justify and authorize the implementation of the method according to the invention, the height of the stack of objects must be substantially less than the height of the box, which is almost always the case. FIG. 3 shows said box 1 after the first stages of implementation of the method according to the invention. In this figure, we see the objects 3, 4, 5, 6 and 7, previously arranged in the box 1. We also see the upper part lah, 1 bh, lch and 1 dh of each of the side walls la, lb , lc and ld of the box 1, said upper parts being located above the level of the top of the stack of objects, that is to say, in the example shown, above the level of the upper face of object 3. It will be seen that the links between said sidewalls at the edges 2ab, 2bc, 2cd and 2da have been partially broken, so that said upper portions lah, lbh, lob and 1dh of said side walls are no longer interconnected, but separated by notches 28ab, 28bc, 28cd and 28da. It can also be seen that said upper portions have been bent outwardly of the box 1 by rotation around folding lines 8a, 8b, 8c and 8d and it will be understood that these are the forces Fa, Fb, Fc and Fd exerted respectively on each of said high parts lah, lbh, lch and ldh, which caused these breaks and caused these folds. During these foldings, are formed said folding lines 8a, 8b, 8c and 8d connecting the bottom of the notches resulting from the connection of said upper parts. It is also understood that it would have been sufficient, in the particular case of the illustrated method, to exert a force on the upper part of two of the four opposite side walls, for example the forces Fa on the upper part lah and Fc on the upper part lch or for example the forces Fb on the upper part lbh and Fd on the upper part ldh, to cause the breaking of the links between the said four high parts lah, lbh, 1 ch and 1 dh two to two but that in this case, only two of said upper portions 30 would have been bent outwardly of said box 1. Figure 4 shows said box 1 at a next step of the method according to the invention. It can be seen in this figure that the four upper parts lah, lbh, lch and ldh of said side walls la, lb, lc and ld have been folded towards the inside of the box 1, by an angle substantially equal to 90 ° relative to the lower part of said side walls. It can be seen that the folding of the upper portions lbh and ldh of the short sides of the box was made before that of the upper parts lah and lch, so that the upper parts lah and lch partially cover the upper parts lbh and ldh after folding. It can also be seen that, in the example illustrated in FIG. 4, the height of the stack of objects is such that the reduction in height of box 1 is small, so that, after folding, , lbh, lch and ldh do not completely close the upper face of said box 1, which has a central opening. FIG. 5 shows said box 1 at the same stage of the process as in FIG. 5 but in another example of implementation of this method. In this figure, it can be seen that the four upper parts lah, lbh, lch and ldh of said side walls la, lb, lc and ld have been folded towards the inside of the box 1, by an angle substantially equal to 90 °. It can be seen that the folding of the high parts lbh and ldh was done before that of the upper parts lah and lch, so that the upper parts lah and lch cover the upper parts lbh and ldh after folding. It can also be seen, in the example illustrated in FIG. 5, that the upper parts lah, lbh, 1 ch and ldh completely close the upper access opening to the contents of said box 1, after folding said upper parts in the direction from the center of said box. It is understood that the height of the stack of objects previously arranged in said box 1 in the example illustrated in FIG. 5, is less than the height of the stack of objects previously arranged in said box 1 in the example illustrated on FIG. FIG. 4, so that the reduction in height of the box 1 in the example illustrated in FIG. 5 is, therefore, greater than the reduction in height of said box 1 in the example illustrated in FIG. For this reason, the height of said high parts lah, lbh, lch and ldh before folding is, therefore, greater in the example illustrated in FIG. 5 than in the example illustrated in FIG. 4, and that for this same reason, said high parts lah, lbh, lch and ldh occupy, once folded, a larger area in the example illustrated in Figure 5, which allows them to completely close the opening of said box 1 We also understand that in the ca s of a rectangular section box, as illustrated in Figures 1 to 5, it is the two upper parts lah and lch side walls la and lc parallel to the length of the box which, once folded, can completely closing the opening of said box 1, provided that the height of each of said high parts lah and lch before folding is equal to or greater than the half-width of said box 1, which is possible only if the height of the stack of objects previously disposed in said box 1 is equal to or less than the initial height of said box 1 minus the half-width of said box 1.
    [0007] It is therefore understood that it is sufficient not to fill the box 1 above a limit located at a distance equal to the half-width of said box 1 relative to the top of said box 1 to be able to completely close the opening of said box 1 by the implementation of the method according to the invention.
    [0008] Finally, it is conceivable that it is sufficient to maintain in the horizontal plane said folded high parts lah and lch, by means of a fastening method known per se or within the reach of those skilled in the art, for example by gluing, strapping, applying adhesive tape, wrapping with a plastic film or a sheet of paper or any other equivalent means, which keeps closed said box 1.
    [0009] According to another characteristic arrangement of the method of the invention, for exerting said effort Fa, Fb, Fc and Fd on said side walls la, lb, 1c and ld and folding the upper parts lah, lbh, lch and ldh of said sidewalls to outside said box 1, said side walls are grasped in an area between the top of said box and the level of the top of said stack of objects 3, 4, 5, 6 and 7 and, preferably, close to said vertical edges Zab, 2bc, 2cd and 2da, for example using tongs 9a1 / 10a1, 9a2 / 10a2, 9b1 / 10b1, 9b2110b2, 9c1 / 10c1, 9c2 / 10c2, 9d1 / 10d1 and 9d2 / 10d2 having, each, at least two jaws, one (9a1, 9a2, 9b1, 9b2, 9c1, 9c2, 9d1 and 9d2) acting on the outer face of the wall, the other (10a1, 10a2, 10b1, 10b2, 10c1, 10c2, 10d1 and 10d2) acting on the inner face of the wall. Each clamp 9a1 / 10al, 9a2 / 10a2, 9b1 / 10b1, 9b2 / 10b2, 9c1 / 10c1, 9c2110c2, 9d1 / 10d1 and 9d2 / 10d2 comprises two elongate jaws, 9a1, 9a2, 9b1, 9b2, 9c1 respectively. 9c2, 9d1 and 9d2, 10al, 10a2, 10b1, 10b2, 10c1, 10c2, 10d1 and 10d2, whose opening and closing are obtained by means of jacks or other actuators (not shown) for exerting on at least l one of the jaws and, preferably, on each of said jaws, a force that tends to bring them closer to the jaw which is opposite, on the other side of the side wall of the box. After positioning the clamps on the upper parts of the side walls of the box, each of said grippers and thus each of said high parts is rotated towards the outside of said box 1, around an axis of rotation 11a, 11b. , 11c and 11d substantially located on said side walls and at the top of said stack of objects. FIG. 6 shows said box 1 at one of the first steps of the method according to the invention. In this figure, we see means set up to grip the upper part of the side walls 1a, 1b, 1c and 1d of said box 1, in the form of pairs of clips 9a1 / 10al, 9a2 / 10a2, 9b1 / 10b1, 9b2110b2, 9c1 / 10c1, 9c2110c2, 9d1 / 10d1 and 9d2 / 10d2 each having two jaws, one 9a1, 9a2, 9b1, 9b2, 9c1, 9c2, 9d1 and 9d2 acting on the outer face of the wall, other 10a1, 10a2, 10b1, 10b2, 10c1, 10c2, 10d1 and 10d2 acting on the inner face of the wall. It can be seen that, in the example illustrated in FIG. 6, the upper part of each of said sidewalls is grasped by two clamps and that these clamps are located near the vertical ridges Zab, 2bc, 2cd and 2da at which said walls side are connected together in pairs. It is understood that it would also be possible to use a single plier of large width to grasp each of said side walls, or even a larger number of pliers 10 less wide. FIG. 6 also shows that the lower end of the jaws of said clamps is at an altitude substantially equal to that of the top of the stack of objects previously arranged in said box 1, that is to say, in the example shown, above the level of the upper face of the object 3. Figure 7 shows said box 1 in the next step of the method according to the invention. In this figure, it can be seen that each of said clamps 9a1 / 10a1, 9a2 / 10a2, 9b1 / 10b1, 9b2 / 10b2, 9c1 / 10c1, 9c2 / 10c2, 9d1 / 10d1 and 9d2 / 10d2 has pivoted about a horizontal axis 11a, 11b, 11c and 11d located on the side wall 1a, 1b, 1c and 1d previously gripped by said clamps, at an altitude substantially equal to that of the lower end 20 of the jaws of said clamps, which is known to be substantially identical to the altitude of the top of the stack of objects previously disposed in said box 1. It is understood that the fact of rotating said clamps allowed to exert a tilting effort on the upper part lah, 1 bh, lch and ldh said sidewalls, directed outwardly of the box 1 and that this effort has been transmitted on the links between said two high parts two by two, and allowed to break these links and it is because this rupture occurred that said upper parts could be folded outward of said It can thus be seen that said links have been broken by the simple effect of this rotational movement, without the direct action of any member on said links or the use of any cutting tool. It is also understood that it would have been sufficient to rotate only the clamps 9a1 / 10al, 9a2 / 10a2, 9c1 / 10c1 and 9c2 / 10c2 around horizontal axes parallel to the length of the box 1, or only the clamps 9b1 / 10b1, 9b2 / 10b2, 9d1 / 10d1 and 9d2 / 10d2 about the horizontal axes parallel to the width of the box 1 to break the connections between said two high parts in pairs but that, in this case, only two of said high parts would have been folded outwardly of said box 1.
    [0010] After breaking the connection between the high parts 1 ah, 1 bh, 1 hp and 1 dh, the side walls 1a, 1b, 1c, 1d of the box 1, said upper parts are separated by notches 28ab, 28bc, 28cd and 28da. After openings of the clamps and removal thereof, said upper parts are then folded towards the inside of the box, by means such as pushing bodies known by the state of the art, so as to bring them back into a horizontal or substantially horizontal plane thus constituting the upper closing wall of said box. During this folding, the upper parts are flaps or flaps that pivot about the axes 11a, 11b, 11c, 11d, creating fold lines 8a, 8b, 8c, 8d.
    [0011] It is understood that the clamps serve only to grip and bend outwardly said upper parts which then return to the vertical starting position. Their inward folding therefore occurs after removal of said clamps, for example on another machine station. FIG. 8 is a sectional view of the box 1 and of a machine part for carrying out the method according to the invention, in a plane parallel to the width of said box 1 and passing through the center of said box 1. In this figure, we see the clamps 9a1 / 10a1 and 9c2 / 10c2 intended to grip respectively the upper parts of the side walls 1a and 1c of said box 1. FIG. 8 also shows the feeler 12, movable along a vertical axis in relation to auditing tongs, and the detector 13 which has the function of detecting the position of said probe 12. The probe 12 may be constituted by a plate whose shape and dimensions correspond approximately to the shape and 1. The detector 13 may consist of a device known per se. This detector 13 can be mounted with a vertical movement aptitude with respect to the probe 12. For this purpose, it can be carried by a slider 26 mounted with a possibility of sliding on a vertical slideway 27 whose lower end is provided with the feeler 12 (Figures 8 and 9). FIG. 8 also shows the objects 3, 4, 5 and 7 previously arranged in said box 1. It is noted that the elements situated in the background of this section, such as the clips 9d1 / 10d1 and 9d2 / 10d2 were not drawn for the sake of clarity. Figure 9 is similar to Figure 8 but shows the box 1 and said machine part in a next step of the method according to the invention. FIG. 9 shows that said grippers 9a1 / 10a I, 9c2 / 10c2, said feeler 12 and said detector 13 have been moved towards said box 1, by means not shown, such as for example cylinders or other actuators associated with a belt transmission, chain, crank / crank-type mechanism or any other suitable means, such that the upper part lah of the side wall has been introduced between the two jaws of the clamp 9a1 / 10a1 and that the upper part 1c of the side wall 1a has been introduced between the two jaws of the clamp 9c2 / 10c2. It is also understood that a similar result could have been obtained by moving said box 1 towards said clamps 9a1 / 10a1 and 9c2 / 10c2, and towards the assembly constituted by said probe 12 and said detector 13. It can also be seen that, when this movement, said feeler 12 first comes into contact with the object 3 whose highest point is the top of the stack constituted by said objects, which stops the downward movement of said feeler 12, and that the movement said clamps 9a1 / 10a1 and 9c2 / 10c2 and said detector 13 continued until said detector 13 comes into contact with said probe 12 and it is understood that the control system which controls said displacement then stopped this movement. It is also seen that the position of said detector 13 is such that the contact between said detector 13 and said probe 12 occurs when the lower end of the jaws of said clamps 9a1 / 10a1 and 9c2 / 10c2 is at an altitude substantially equal to that the highest point of the object 3, that is to say at an altitude equal to that of the top of the stack of objects previously disposed in said box 1 and that this is true regardless of the height of said stack of objects. The folding of the upper parts lah, 1bh, lch, ldh, in the horizontal position, towards the center of the box 1, can be favored by providing horizontal creases or grooves at the axes 11a, 11b, 11c, 11d, these creases or grooves may occupy the entire distance between the bottom of two consecutive notches 28ab, 28bc, 28cd and 28da or only part of this distance. They are obtained by crushing the material used for the manufacture of the box, for example under the pressure of a suitable tool. It can be seen, for example in FIGS. 8 and 9, that the jaws 9a1, 10a1, 9c2 and 10c2 each have in the lower part, a beveled edge 25, these beveled edges being arranged facing one another (Figure 8), which allows them to crush the side walls 1a and 1c in this area, on the approximation said jaws of the clamp. It is known that this zone corresponds to the position of the axes 11a, 11b, 11c, 11d, around which we will then rotate said clamps 9a1 / 10a1 and 9c2 / 10c2 and thereby the upper part lah and lch said sidewalls the and the, facilitating the creation of folding lines 8a and 8c. It is understood that these creases or grooves, 35 are intended to facilitate the folding of said upper parts of the side walls towards the inside of said box 1. It is also understood that these creases or grooves may be of reduced length, sufficient to promote the creation of fold lines 8a, 8b, 8c, 8d, over the entire length of the short sides and the long sides of the box 1, but can also advantageously be made on all or part of the distance between the bottoms of the notches 28ab, 28bc, 28cd and 28da located on the axes 11a and 11c and around which will be folded said high parts lah and 1 hp, this using clamps large width. According to an alternative embodiment, only one of the two jaws of each clamp may comprise a beveled edge 25 for making grooves or grooves in one side of the side walls of the boxes made of cardboard or other foldable material. Finally, it will be understood that the explanations given for the mechanisms that appear in FIGS. 8 and 9 which represent sectional views in a plane parallel to the width of said box 1 are also applicable for the mechanisms that would appear on other sectional views. for example in a plane parallel to the length of said box 1 if the corresponding figures were made. FIG. 10 shows said box 1 before implementing the method according to the invention. FIG. 10 shows the four lateral walls 1a, 1b, 1c and 1d of said box 1. The edges 2ab, 2bc, 2cd and 2da where the connections between said sidewalls two by two are also seen. It is also seen that said box 1 has a cutout 14ab, 14bc, 14cd, 14da, made at the vertical edge 2ab, 2bc, 2cd, 2da where is the connection between said side walls la and lb, 1 lb and 1c, 1c and 1d, 1d and 1c. This cutting was performed on a reduced height, for example on a height of the order of a few millimeters, from the top of the box. It is understood that such a cut of reduced height is intended to facilitate the implementation of the method according to the invention in the sense that it constitutes a breaking primer from which the breaking of the connection between said side walls of the box. 1, for example between the side walls 1a and 1b, will be able to easily propagate to the level of the top of the stack of objects previously arranged in said box 1, during the folding of the upper parts lah and 1bh of the side walls 1a and 1b of said box, in the context of the implementation of the method which is the subject of the invention, as described for example in the explanations given for FIG. 7. Likewise, the cutouts 14bc, 14cd and 14da and it is understood that these play the same role for breaking the bonds between, respectively, the side walls 1a and 1b, 1c and 1d, and 1d and 1a.
    [0012] It is also known that, for the complete implementation of the method according to the invention, making it possible to obtain a closed box, as described for example in the explanations given for FIG. 5, the height of each of said high parts lah, 1bh , lch and 1dh must be at least equal to the half-width of said box 1, and that, therefore, said cutouts 14ab, 14bc, 14cd and 14da may have a height at most equal to the half-width of said box 1 so that, under these conditions, the low point of said blanks will always be located above or possibly at the same level as the top of the stack of objects previously housed in said box 1. FIG. 11 shows said box 1 after placing implementation of the first steps of the method according to the invention. It is known, through the explanations given for FIG. 5, that the box 1 can be kept closed after the implementation of said method by providing means for maintaining in the horizontal plane said upper parts 1a 1 and 1h after folding of said upper parts to the In the interior of said box 1, FIG. 11 shows said top portions 1bh and 1dh, already folded towards the inside of said box 1, in the horizontal plane. We also see said high parts 1ah and 1ch, not yet folded and we see on the inner side of the upper part lch a bead of adhesive 15, deposited near the upper upper edge of said upper part lch. It is therefore understood that said adhesive bead 15 will be brought into contact with the outer face of the upper part 1ah if said upper part lah is folded towards the inside of the box 1, in the horizontal plane, before folding back also said upper part 1 ch inward of said box 1, in the horizontal plane. It is therefore understood that said adhesive bead 15 will make it possible to bind said high parts 1ah and 1ch together after folding and, thereby, to maintain them, as well as said high parts lbh and ldh, in the horizontal plane, thereby providing means for holding said box 1 closed. FIG. 12 shows said upper portions 1bh and 1ddh, already folded towards the inside of said box 1, in the horizontal plane. We also see said high parts lah and lch, not yet folded and we see on the inner side of the upper part lch a bead of adhesive 15, deposited near the upper upper edge of said high portion 1ch. We also see on the inner face of the upper part lah two beads of adhesive 16 and 17, deposited near the upper upper edge of said upper part 1ah. And we see also a bead of glue 18, deposited on the outer face of said folded upper part 1HD and a bead of glue 19, deposited on the outer face of said upper part lbh folded. It will therefore be understood that, if the upper part lah is first folded towards the inside of the box 1, in the horizontal plane, said adhesive beads 16 and 18 will make it possible to bond said upper parts 1 a 1 and 1dh between them and said glue beads 17 and 19 will allow to bind said high parts 1ah and lbh between them and, thereby, to maintain them in the horizontal plane and that if one folds then said high part lch to inside said box 1, in the horizontal plane, said adhesive bead 15 will make it possible to bind said upper parts 1ah and 1ch together and, thereby, to maintain them, as well as said high parts lbh and ldh, in the horizontal plane. It is therefore understood that these different adhesive beads 15, 16, 17, 18 and 19 provide means for keeping said box 1 closed, in a reliable and hermetic manner, irrespective of the height of said high parts 1ah, 1bh, 1ch and ldh, between the half-width and the width of said box 1. FIG. 13 shows said box 1 after the first steps of the method according to the invention. It can be seen in FIG. 13 that the upper part 1dh, and also the upper part 1bh which is no longer visible in this figure, have been folded towards the inside of the box 1, in the horizontal plane. It is understood that said folding was carried out at the top of the stack of articles previously arranged in said box 1. It is also seen in Figure 13, the adhesive beads 15, 16, 17, 18 and 19. We see that said adhesive bead 15 is deposited on the upper part 1ch, that said adhesive beads 16 and 17 are deposited on the upper part 1ah and it is known from FIG. 12 that said bead of adhesive 18 is deposited on the folded upper part ldh and said adhesive bead 19 is deposited on the folded upper part 1bh. FIG. 13 also shows a sizing system consisting of an adhesive reservoir 20, sizing nozzles 21, 22 and 23 and a pipe 24 which connects said sizing nozzles to said reservoir. It is understood that said gluing nozzles may each be provided with a device, not shown in FIG. 13, enabling them to project glue when the control system of said gluing system gives the order. It can also be seen that said adhesive beads 15, 16, 17, 18 and 19 are all parallel to each other, and it is therefore easy to remove said adhesive cords by moving said box 1 under said adhesive system. gluing in the direction D parallel to said glue beads and ordering, by said control system, the projection of the glue for each of said glue nozzles 21, 22 and 23 at the appropriate time for said glue beads to be deposited on said high parts 1ah, lbh, 1ch and ldh at the desired location. From the foregoing description, it is again retained that the machine according to the invention comprises means making it possible, on the one hand, to exert a force directed outwards on the upper part (l ah, lbh, lch, ldh ) at least two opposite side walls (1a, 1c or 1b, 1d) of a box 1 made of a foldable material such as cardboard or the like and consisting of a bottom 1c and 4 side walls (1a, 1b, 1c, 1d) connecting together and forming 90 ° angles, so as to break the connections between said upper parts, and, secondly, to then fold all the upper parts (1 ah, lbh, lch, ldh) towards the inside of the box to bring them back to a substantially horizontal plane. This machine thus makes it possible to adapt the height of the useful volume of the box to the height of the set of objects or the stack of objects (3, 4, 5, 6, 7) housed in said box. According to the invention, said means consist of a tooling comprising at least two clamps (9a1 / 10a1, 9a2 / 10a2, 9b1 / 10b1, 9b2110b2, 9c1 / 10c1, 9c2 / 10c2, 9d1 / 10d1, 9d2 / 10d2) comprising , each, at least two vertical jaws secured, on the one hand, to a first motorization to bring them closer to each other in order to grasp, by a pinching action, the upper part of at least two side walls of the box, and secondly, a second motorization for applying a force (Fa, Fb, Fc, Fd) directed outwards, on said high parts of said two side walls, so as to break the links between them.
