    [0001] Adjustable angle mechanism for crimp-lock machine without deformation of leather and/or synthetic materials
    [0002] The present invention relates to a crimp-lock mechanism for leather and/or synthetic materials that can provide the upper formation for a suitable usable flawless footwear component, without the need for re-cutting, that is designed, manufactured and marketed exclusively by the first time applicant.
    [0003] The present mechanisms known to those skilled in the art of crimp-lock machines, i.e., the method in which a purposeful and geometrically calculated cut, based on a relevant shoe last and a relevant shoe design for that last, a piece of leather is formed to have an abrupt angle in order to be placed and further processed (stitched, glued, etc.) in the toe and neck area of a high-top shoe, consists of two different approaches.
    [0004] The oldest system, in a general description according to the prior art shown in figure 1, consists of two metal plates (11), which retain the piece of leather to be shaped, and then said piece of leather is forced through of an adjustable opening (12), which stretches the material to give the desired shape.
    [0005] The newest system, according to the prior art shown in Figure 2, is a flexible male mold (13), of various shapes and sizes, in which the piece of leather is placed and then pressed onto a mold (14), in a relevant way that provides a folded shape to said piece of leather.
    [0006] Both prior art mechanisms mentioned above have various problems. The plate mechanism, due to the nature of the procedure, plastically deforms the leather, creating wrinkles in the procedure and irregularly deforms the geometry of the part to such an extent that, in order to be used, it must be cut out on a cutting template. adequate after the operation causing, therefore, a waste of time and materials, while most synthetic materials cannot be processed by this system, since the nature of the procedure destroys the surface of the material in most cases, and yet another big problem is that, since the shape of the metal plates is fixed, the system can only produce one angle and therefore any further needed angle requires replacement of the plates, this being a costly and time consuming procedure. weather.
    [0007] The newer system with the elastic mould, while able to produce a wrinkle-free formed part, achieves very limited angles, while the nature of the pressing creates a lot of compression in the center of the part, which decreases rapidly as it radiates outwards. part edges. Any effort to increase the final angle by pressure results in the materials stretching and wrinkling beginning, as over-stretching of the elastic mold causes excessive elongation resulting in warping. This system is suitable for synthetic materials, also since it is formed based on a more female-male mold type principle and not on a drawing principle, and although the angle of the formed part can be varied by adjusting the pressing pressure, the angles The maximums achieved are far from desirable, and finally it can only handle simple geometries and cannot produce the necessary abrupt angles as the plate system can.
    [0008] The objective of the present invention is to overcome and eliminate all the problems and disadvantages of the prior art mentioned above, providing a new mechanism for crimping-locking leather and synthetic materials, which can provide the materials with the necessary desired angles without irregular deformations, being said adjustable angles, which can also work with any type of material, and eliminate the need for trimming or ironing after the procedure, as well as evenly pressing the entire area of the material.
    [0009] According to the present invention, an adjustable angle mechanism for a crimping-locking machine without deformation of leather and synthetic materials is provided, consisting of a main frame (9), a secondary housing mobile frame (10), which houses two cylinders ( 6) for bending, and a displacement cylinder (7), in which said mobile secondary housing frame (10) moves itself by means of another suitable cylinder (8), and moves towards a fixed female mold (1) . In said housing frame there are two rocker plates (5) with a pivot point each (4), and in said plates (5) there are two sliding surfaces (3), with openings that house and lock in position a mold (2) flexible male, also controlling its elongation, and said mechanism of the invention can achieve many different angles without irregular deformations that can be adjusted without the need to change the molds, works with any type of material and eliminates the need to trim or iron afterwards of the procedure, and also guarantees a uniform pressing of the entire area of the material, and almost zero elongation of the flexible male mould.
    [0010] Additional benefits and advantages of the present invention will become apparent upon careful reading of the detailed description with appropriate reference to the accompanying drawings, in which:
    [0011] Figure 1 shows the prior art fixed shaped plate mechanism, in a perspective view, Figure 2 shows the prior art flexible mold mechanism, in a perspective view,
    [0012] figure 3 shows the mechanism of the invention, in a perspective view,
    [0013] Figure 4 shows the mechanism of the invention, in a cross-sectional plan view, in the rest position, and
    [0014] Figure 5 shows the mechanism of the invention, in a cross-sectional plan view, in the pressed position.
    [0015] More particularly, referring to the drawings and figures 3-5, an adjustable angle mechanism for a crimping-locking machine without deformation of leather and/or synthetic materials, according to the embodiment of the present invention, comprises a frame (9) main, a mobile frame (10) for secondary accommodation, a small transverse cylinder (7) of said mobile frame (10) for secondary accommodation, a main transversal and pressing cylinder (8), two bending cylinders (6) joined by appropriately in the secondary mobile frame that drives each of them, a plate (5) that each pivots on a rod (4), while said plates (5) are joined by two sliding surfaces (3) that house and lock in place a flexible male mold (2), said mechanism being characterized in that, when activated and pressed against a fixed female mold (1), due to its overall design, it can copy the shape of said mold (1) fixed female, hand ra male-female, is also characterized in that it can eliminate the need to cut deformations in the material after the procedure, since the design of the mechanism results in a pressing and bending movement that is made possible by synchronizing the movements (8, 6) of cylinder that actuate the two rocker plates (5), by means of the pivot points (4), plates in which the two sliding surfaces (4) with openings house and lock said male mold (2) in position flexible, resulting in almost zero elongation of the flexible male mold (2), thus achieving a conformation of the material without changing the overall geometric shape of the material, also controlling its elongation, in addition, said mechanism can achieve many different angles, by means of to control the bending cylinders (6) independently, without the need to change the moulds, it also works with any type of material and eliminates the need to r trimmed or ironed after the procedure, and also uniformly throughout the material area, since, when a piece of material is placed in the flexible male mold (2), the two transverse cylinders (7, 8) are activated in sequence and then the bending cylinders (6), causing said flexible male mold (2) to bend in two arcs from the front and back, copying said fixed female mold (1), thus uniformly shaping and pressing the overall area of the processed material, and during the circular movement said sliding surfaces (6) control the elongation of said flexible male mold (2), keeping it under control since they can slide on said rocker plates (5) thereby achieving the required movement without elongation movement of said flexible male mold (2).
