    equal to the length of the cylinder 2 circumferentially provided with a coating 9 of an elastic material, and an element 10 having a cross-section, located on the support 7 on the section 11 opposite to the base 8.
    The method of fixing the printing plates on the form cylinder (in this case with two printing plates) of the printing press for coil-type graphing is carried out as follows.
    Plate cylinder 2 is prepared by conventional methods and is made in the form of a cylindrical jacket, the inner wall 12 of which has a slight taper. The engraving of the plate is also carried out by known methods, engraving an image printed on a coil (not shown) on two nickel plates. Then both plates are bent, passing them through a set of rollers, and their radius corresponds to the radius of the cylinder, they are exactly from 30

    cut across the width and length so that the 25-linDra was solid. The second plastic plate corresponded to the length and outer semicircle of the cylindrical jacket 2. The cylindrical jacket 2 is placed on the shaft 1, which has a taper corresponding to the taper of the wall 12 of the cylindrical jacket 2. The shirt 2 is advanced to obtain a radial stretch corresponding to the stretching to which subject to the plate cylinder when it is mounted on a printing press shaft (not shown). Stretching corresponds to an increase in the diameter of the cylinder 2 by approximately 0.2 mm.
    Then, a layer of glue, in particular a film of epoxy glue, is applied to half of the surface of cylinder 2 in the direction to the periphery of its jacket, and the film actually covers a little more than half of the surface of the cylinder. On the surface coated with epoxy film, place the first printed form in the form of a plate 4, precisely placing it on the cylindrical jacket 2 so that both its edges are parallel to the shaft 1 of the cylinder. To fit and hold the plate 4 in this position, for example, you can use two rings (not shown) screwed into the shaft 1 on both sides of the cylindrical jacket 2, the diameter of which is larger than the diameter of the shirt and on which fingers x can be placed (not
    5 is held in place by temporary means, such as a force of gravity, rotating shaft 1, so that the second plate 5 is on the upper half of the cylinder.
    Then, on the first plate 4, a collapsible steel strip 3 is installed, the width of which is equal to the length of the plate cylinder, and the length is longer than its semicircle.
    Both ends of the tape 3 are provided with two L-shaped profiles 13 and 14. The edges of the tape 3 are fastened to one of the profile shelves with screws 15 and 16. The second shelves of profiles 13 and 14 are provided with cut holes.
    On the second plate 5, a support 7 is mounted with its cylindrical concave surface provided with an elastic material 9 to prevent the surface surface of the plate 5 from FOB45. Element 10 having a cross-section is mounted on the upper part of support 7. Element 10 may be mounted on support 7, for example, by welding
    50 or screwed. Both levers of the element 10, which extend beyond the support of the support 7, are provided with holes, into which bolts 17 enter, screwed into the cut holes of profiles 13 and 14. Screwing or unscrewing bolts 17 from the cut holes increase or decrease the tensile force on tape 3.

    is shown) projecting axially in the direction towards the cylindrical jacket 2 for axial support of the printing form 4 o. The fingers interact with sockets (not shown) made for this purpose on the folded edges of the plate 4.
    The correctly installed plate 4 is fixed in this place with the help of two rivets (not shown), which can be inserted near both the bent edges of the plate. The rivets interact with two corresponding holes made in the cylindrical jacket 2.
    Then, behind the graphed plate 4, on the second half of the cylindrical jacket, a sheet is formed that is formed by a second non-engraved plate 5 having exactly the same dimensions as the second engraved plate, which is subsequently attached so that the side surface of the mold
    linDra was solid. Second plate
    5 is held in place by temporary means, such as a force of gravity, rotating shaft 1, so that the second plate 5 is on the upper half of the cylinder.
    Then, on the first plate 4, a collapsible steel strip 3 is installed, the width of which is equal to the length of the plate cylinder, and the length is longer than its semi-circle.
    Both ends of the tape 3 are provided with two L-shaped profiles 13 and 14. The edges of the tape 3 are fastened to one of the profile shelves with screws 15 and 16. The second shelves of profiles 13 and 14 are provided with cut holes.
    On the second plate 5, the support 7 is mounted with its cylindrical concave surface provided with an elastic material 9 to prevent the surface of the plate 5 from being DAMAGED. On the upper part of the support 7 there is an element 10 having a cross-section. Element 10 may be mounted on support 7, for example, by welding
    or screwing. Both levers of the element 10, which extend beyond the support of the support 7, are provided with holes, into which bolts 17 enter, screwed into the cut holes in profiles 13 and 14. Screwing or unscrewing bolts 17 from the cut holes increase or decrease the tensile force by tape 3.
    Before applying the tensile force, the adhesive film is heated between the plate 4 and the cylindrical jacket 2, heating up, for example, shaft 1. When the glue is well softened, the tape 3 begins to stretch, applying tensile forces using bolts 17. First tighten the bolts, located in the middle of the element 10, and continue to drag symmetrically to the edges. Thus, the excess glue is pushed out to the edges and removed, since the accumulation of the remaining glue under the plate 4 can lead to deformation of the latter and, therefore, the lateral surface of the mold cylinder.
    At the joints L and B between the plates 4 and 5, the lateral surface of the plate cylinder is solid, and the tensile forces acting on the entire plate 4, including both edges, are uniform. To ensure this uniformity, to eliminate the damage, on the edges of the plate 4, to ensure the continuity of the surface at joints A and B, a film of glue is applied on more than half of the side surface of the cylindrical jacket.
    When the required tightening is achieved, the heating of the glue is stopped and it is cooled artificially or naturally. When the cooling is completed, remove the tape 3, the support 7, the element 13 and the plate 5, peeling off both its edges near joints A and B, apply a film of glue on the second half of the surface of the cylindrical shirt, place the second engraved plate, surround it with tape 3, and then enter , as stated above. Moreover, in this case, the base 8 of the support 7 rests on the surface of the engraved plate 4, previously glued. When the fixing of the second plate is completed, remove the tape 3 and support 7 "
    Then fill the groove between the edges of both engraved plates as follows.
    If the image printed on the coil during one full turn of the cylinder is not solid along the straight joints between the plates, i.e. there are empty spaces extending axially on the plates and corresponding parts of the paper to be cut and removed when trimmed, in which case the grooves are filled with epoxy glue
    and after it has been cured, it is processed to obtain sufficient continuity of the side surface of the cylinder. If the image printed on the coil should be made solid opposite the joints, then it is necessary that the lateral surface of the plate cylinder be completely solid.
    In this case, the grooves are filled with electrodeposition or welding, for example laser, with the same material from which the plates are made, in particular with nickel, and then treated
    the surface, until a completely solid side surface is obtained, or by milling (or otherwise) create a uniform groove, preferably of rectangular cross section, between
    0 by the adjacent edges of both plates and a strip is introduced into it from the same material from which the plates are made, preferably nickel, having dimensions corresponding to the dimensions
    5 grooves, and then process this part to obtain a solid side surface of the cylinder.
    After finishing the surface grinding, remove the form cylinder from the shaft. A layer of chromium was worn over the entire lateral surface of the plate cylinder, immersing it in an electrolytic bath (layer of chromium 8-10 µm).
    Instead of using the second plate 5 when gluing the first graded plate 4, two strips can be used, placed behind both edges of the plate 4, but their installation is somewhat difficult and it is preferable to use a whole plate.
    More plates can be attached to the cylinder, for example three.
    The proposed method of fastening the plates on a cylindrical jacket
    5 is simpler and cheaper and allows for the continuity of the lateral surface of the plate cylinder and, consequently, an increase in print quality.
