    The invention relates to the equipment of printing companies, in particular to a serrated knife for perforating signatures before folding in a printing machine.
    The aim of the invention is to improve the quality of perforation.
    FIG. 1 shows a perforated toothed knife mounted in a cutting cylinder, a slit; in fig. 2 - the same, with a U-shaped implementation of the cutting edges of the teeth, side view; in fig. 3 shows the perforated teeth of a knife along the fold line: in FIG. 4 - knife tooth; in fig. 5 shows a serrated knife with an H-shaped configuration of the cutting edges of the teeth; in FIG. 6 - perforation, made with a knife with H-shaped performance of the cutting edges of the teeth; in fig. 7 - the proposed knife embodiment; in fig. 8 - perforation, made with a knife according to FIG. 7
    The folding device of the rotary printing machine has a perforation drum 1, in which a recess 2 is made in its width. In the latter, a beam 3 is provided with a hole 4 for mounting the toothed knife 5. In the direction of rotation of the perforating drum 1, there is a spring-loaded front and rear teeth of the toothed knife 5 clamp b, which presses the signature 7 to the perforating counter-drum 8 and thus prevents the signature 7 from being shifted during the perforation. When this, the serrated knife 5 interacts with the flexible counter-plate 9 attached to the perforating counter-drum 8.
    The serrated knife 5 is made detachable and consists of two thin-walled plates 10 and 11 (for example, 1 mm), which have a slightly larger width than the signature 7

    The plates 10 and 11 are preferably made identical and the reverse sides 12 and 13 are attached to each other in the beam 3 so that they perform the function of a single blade. Each plate 10 and 11 (Figures 2-4) has a plurality of perforation teeth 15 and 16 on the top edge 14. With the exception of the teeth located in the middle of the knife marked with the letter M, all the perforation teeth 15 and 16 have the same width and are set to from each other so that between two adjacent punching teeth 15 a depression 17 is formed, and between two adjacent punching teeth 16 - a depression 18. Installed in the middle of each steel plate 10, 11 the punching teeth have a slightly larger width than the other punching teeth 15 and 16. As a result, when connecting the reverse sides of both parts of the punching knife 5, there is no cavity between the two central punching teeth of the knife.
    The main cutting edges 19 and 20 of the punching teeth 15 and 16 are located on the joint straight 21. The valleys 17 and 18 are slightly larger than the perforated teeth 15 and 16. The location of the punching teeth 15 and 16 and the valleys 17 and 18 is chosen so that each the perforation tooth 15 almost (leaving a small gap a of about 0.5-3 mm) covers the cavity 18, and the perforation tooth 16 g depression 17. The gap a is the distance between the side cutting edges 22 and 23 of two immediate adjacent perforating teeth 15 and 16,
    Each punching tooth 15 and 16 is sharpened on one side along the cutter pattern toward the main cutting edge 19 and 20 and has two additional side cutting edges 22 and 23 on the inclined lateral sides 24 and 25. The additional cutting edges 22 and 23 are in contact with the ends of the main cutting edges 19 and 20 and are set at an angle a, / 3 (for example, (f / 3 90 °) with respect to the main cutting edges 19 and 20. It goes without saying that the angles ft can have a different value.
    The cutting edges 19 and 22 and 20 and 23 of the punching teeth 15 and 16 are made U-shaped, with the side cutting edges 22 and 25 of the immediately adjacent teeth 15 and 16 located on opposite sides of the joint straight. The main cutting edges 19 and 20 of all the punching teeth 15 and
    The 16 are located on or near the joint right 21, and the two side cutting edges 22 and 23 of the two immediately adjacent perforating teeth 15 and 16 are turned to each other.
    to a friend at 180 ° around the provided right 21.
    At the lower edge 26, the knife 5 has a plurality of recesses 27, by means of which it is made with the possibility of vertical,
    0, but not horizontal, movement in the recess 4. A plurality of rectangular recesses 28, also made on the lower edge 26 of the knife 5, are used to accommodate installation wedges (not shown).
    5 In addition, it is possible and complete execution of the punching knife 5.
    The punching knife 5 (Fig. 2-4) performs the perforation in the multilayer signature 7, which consists in that the signature 7
    0 along or near (for example, ± 0.2 mm) fold line 29 has a plurality of alternately extending U-shaped perforations 30. The term alternately means that the main cuts 31 of all perforations 30 lie on or near the provided fold line 29, and Both side cuts 32 and 33 of two directly adjacent perforations 30 are rotated by 180 ° around the fold line 29 in the plane of the signature 7.
    Between the side cutting edges 22 and 23 of the punching teeth 15 and 16 made with the side cuts 32 and 33, the bridge 34 remains small, while
    5, between the two central cuts, which are made wider as a result of the action of the central teeth, the bridge 34 does not remain, so that the fold line 29 has a longer two-fold spline,
    0, which is preferably performed in the middle of the signature in a region coinciding with the middle M of the longitudinal fold.
    The cutting edges 19 and 22 of the perforation teeth 15 of the toothed knife 5 mounted at a distance adjacent to each other are H-shaped (Fig. 5). In this case, the main cutting edges 19 of the punching teeth 15 are located along the bulkhead straight 21 and two punching edges.
    The 0 teeth, made in the middle M, coinciding with the foreseen longitudinal fold, are placed tightly together (so that there is no distance a between the punching teeth 15). Two directly adjacent cutting edges 22 forming a cavity 18 can be placed in parallel (Fig. 5).
    The toothed knife 5 according to FIG. 5, in the multilayer signature 7, performs a perforation, in that the signature 7
    along or near the fold line 29 has a set of H-shaped perforations 35 extending. There is only a small strap 37 between the lateral cuts of the 3H made with the help of the lateral cutting edges 22, and there is no jumper 37 between the main M-cuts 38 made in the middle.
    Referring to FIG. 7, the cutting edges 19 and 22 of the perforation teeth 15 of the toothed knife 5 located adjacent to each other are made in the form of a lying crank. This means that the corresponding connecting rod main cutting edges 19 are located on the joint right 21, and the corresponding connecting rod pin lateral cutting edges 22 of the punching teeth 15 and the lateral cutting edges 22 of two directly adjacent nepd orienting teeth 15 are placed on different sides of the joint right my. The punching teeth 15 are separated from each other by a depression 18. Only two punching teeth 15, made in the middle of the knife M, which coincides with the provided longitudinal fold, are placed tightly to each other.
    At the ends of the cutting edges 19, the cutting edges 22 are located at an angle y, d, (for example, y 6 90 °) to the edges 19. The angle y, d may have a different value. Preferably, two immediately adjacent lateral cutting edges 22 or their extensions forming the depression 18 are arranged in parallel.
    1 A toothed knife 5 according to FIG. 7 performs a perforation in a multi-layered signature 7, in that the signature 7 has a plurality of perforations 39 made in the form of a lying crank extending along or near the fold line 29. At the same time, the corresponding cuts 40 corresponding to the crank lie on the joint fold line 29, and the side cuts 41 corresponding to the crank pin are placed on opposite sides of the joint straight. At the same time, from the side of the connecting rod 40, the connecting rod fingers 41 are located counterclockwise to the middle of M, and from the middle of M - in the direction of the hour.
    Between the side cuts 41, made with the help of cutting edges 22, there remains a small jumper 42, while the perforation 39, made in the middle of M, consists of two opposite cranks without a jumper 42 between them.
    The advantages of the invention are that signatures with a large number of pages, for example 64, can be stacked well, since the formation of bulges and / or folds is almost completely prevented as a result of deformations.
