    The invention relates to the printing industry, in particular, to devices for fastening and pulling a flexible printing plate onto a form cylinder of a rotary printing machine.
    The aim of the invention is to provide ease of operation and simplify the design.
    The drawing shows the device section.
    In the rotary printing machine installed in rotation on the bed of the printing cylinder 1, there is an axially parallel channel 2 of rectangular cross section, in the upper part of which, in the area of the mouth, there are two edges 3 and 4 for receiving the hook-shaped bent front
    the edges 5 or the rear edges 6 of the printing plate 7. In the middle of the channel 2, a narrow clamping strip 8, for example, 6 mm thick, is installed with the help of two cylindrical bolts 9 at the ends which can be rotated in bearing stands 10. Both cylindrical bolts 9 placed in horizontal holes 11 in both - their end surfaces 12 of the strip 8. Racks for bearing 10 are installed at the ends of channel 2. In order to prevent the output of racks for bearing 10 from channel 2, two disks 13 are provided, which in the area of edges 3 and 4 screws 14 attach enes the plate cylinder 1. The discs 13, multiple input into channel 2 and set out in the triangular Kaal

    ABOUT
    The rail 15 is made in the upper side of the bearing struts 10. In the head part 16, the bar 8 has two triangular grooves 17 on both sides that are symmetrical to receive the bent trailing edge 6 of the printing form 7. In the upper side 18 of the bar 8 there is an opening 19 , which is used to receive the lever bolt 20, which can be inserted through the hole at the end of the printing plate into the hole 19. Under the cylindrical bolts 9 in the bar 8 there is a longitudinal groove 21 extending along the entire length of the bar 8 and reducing the rigidity of the lower part 22. In the end hour and 23 formed spaced apart plurality of apertures 24 extending along the length of strips 8, 24 of these openings covers are fixed magnets 25, made in the form of bar permanent magnets. These magnets are set by both poles.
    26 and 27 for the width of the strip 8. In the zone of the poles 26 and 27, the rod magnets 25 are ground at a slight angle, so that a trapezoid shape is obtained over the cross section, with the long side itself located at the top. The angle of inclination of poles 26 and 27 is obtained from the angle of rotation of the strip 8, so that in the position taken after the rotation, the rod magnets 25 fit snugly with their poles 26 and
    27k ferromagnetic side walls
    28 and 29 channel 2,
    I
    The device works as follows.
    In order to fasten the printing plate 7 on the plate cylinder 1, the bent front edge 5 of the plate is placed on edge 4. The bar 8 is turned in the direction of rotation of the plate cylinder 1, for example, by means of a lever bolt 20. For this, one end of the lever bolt 20 is inserted into the hole 19 of the strap 8 and rotated by hand in the direction of rotation of the cylinder until the poles 27 of the rod magnets 25 adjoin the wall 29 of the channel 2. In this position the magnets 25 hold the bar 8. Now the rear edge 6 of the printing form 7 can be placed in the opposite The direction of rotation of the plate cylinder 1 of the recesses 17 of the bar 8. The printing plate 7 is tightened by turning the bar 8 against the direction of rotation of the plate cylinder 1 until the opposite poles 26 of the bar magnet 25 are adjacent to the ferromagnetic side wall 28 of channel 2, where they are held by magnetic force. In this case, the spring action of the strip 8 is created by the elastic deformation weakened by the longitudinal groove 21 of the lower part 22. Now the strip 8 is in the clamped position. At the same time, due to the oblique execution of the edges 3 and 4 and the notches 17, the printing form 7 is self-supporting, i.e., without special clamping device, held on the forme cylinder 1.
