Definitions

the invention relates to a counter bar for a device for cross perforating signatures according to the preamble of claim 1.
EP 03 07 891 B1 discloses a device for cross-perforating signatures before folding, in which a perforating knife bar of a perforating cylinder acts against a counter bar of a counter-perforating cylinder.
the invention has for its object to provide a rubber-elastic counter bar for a perforating device, in which a damaging setting of the paper dust created during perforating is largely avoided in the incisions made by the individual perforating knife in the counter bar of the perforating device.
the invention has the following advantages in particular: by the penetration of the paper dust into the incisions in the counter bar, with the paper dust subsequently being blown off or sucked off by the in the counter bar bore is always a precise interaction between the perforating knife bar and the profiled by the cutting devices or provided with incisions counter bar. The risk of individual cutting or perforating devices breaking out is thus also reduced.
the arrangement of a support device, for. B. a cylindrical coil spring in the axial bore of the counter bar gives the counter bar according to the invention a long life. A particularly low-pollutant removal of the paper dust is achieved by suctioning off the paper dust.
the counter bar according to the invention can also be used in paper cutting devices.
a folding unit of a rotary printing press shows, among other things a perforating cylinder 1.
the perforating cylinder 1 carries in a cylinder-wide pit 2 a perforating knife bar, denoted overall by 3.
the perforating knife bar 3 has a form-fitting, for. B. connected by screws to the bottom of the pit 2 extending in the axial direction profile strip 4, approximately in the form of a T rotated by 180 °.
each individual perforating knife 8; 9 has a straight perforating part 13 (hereinafter referred to as a straight part) which extends congruently with a future transverse fold line 12 and has a width b and a height h.
Both angled parts 17; 18 are at an angle alpha, z. B. 45 ° to the straight part 13 so that the free ends of the angled parts 17; 18 both in the direction of the plane 11 bisecting the cylinder length and at the same time in the transport direction of a signature 19 or point in the direction of rotation C of the perforating cylinder 1.
Both the angled parts 17; 18 and the straight part 13 of the individual perforating knife 8; 9 each have cutting edges 22 on their side facing a counter-perforating cylinder 21; 23 or a cutting edge 24.
the cutting edges 22 to 24 can each have a one-sided bevel and also a finely toothed cutting edge 22 to 24. Because of the lower height of the angled parts 17; 18 compared to the height of the straight part 13, the undersides of the angled parts 17; 18 supported on the end 6 of the vertical T-leg 7, while the protruding end or tongue 28 of the straight part 13 abuts on a longitudinal side of the vertical T-leg 7 and by means of a parallel and axially extending to the vertical T-leg 7 Terminal strip 31, e.g. B. is clamped by means of screws.
the individual perforating knives 8; 9 can be spaced apart individually at a distance a, ie one tooth gap each, which corresponds to a so-called web 34 between two cuts in the signature 19.
the distance a can be between two and eight millimeters.
the individual perforating knife 8; 9; 36 can be made of folded steel sheet with a thickness d, z. B. exist between 0.5 to 1.5 millimeters.
the individual perforating knife 8; 9 are each formed in one piece and can be arranged symmetrically or asymmetrically to the plane 11 bisecting the cylinder length.
An asymmetrical arrangement of the individual perforating knives 8th; 9 (Fig. 2 and 3) has when perforating multilayer signatures 19, z. B.
the plane 11 bisecting the cylinder length is arranged a middle single perforating knife 36 with a width f, consisting of a straight part 42, the parts 37 of which are angled at an angle alpha to the straight part 42; 38 (FIG. 2) each point in the direction of the plane 11 bisecting the cylinder length and in the direction of rotation C of the perforating cylinder 1.
the lined up and clamped single perforating knife 8; 36; 9 of the perfection knife bar 3 act against an elastic, fixed in a cylinder pit 66 of the counter-perforating cylinder 21, counter bar marked with a total of 67.
the signature 19 is provided with a transverse perforation between the perforating knife bar 3 and the counter bar 67.
the counter bar 67 can have a rectangular, in particular a square cross-section with a continuous bore 68 extending in the longitudinal axial direction to the counterperforation cylinder 21, in which a hollow support device adapted to the diameter i of the bore 68, e.g. B. extends a cylindrical coil spring 69 which bears with its outer diameter on the diameter of the bore 68 (FIGS. 1 and 4).
This coil spring 69 has a length which is greater than the product of the number of turns and the wire diameter of the coil spring 69, so that the turns of the coil spring 69 do not abut one another.
a length of the coil spring 69 of 500 millimeters can account for about 100 turns with a wire diameter of one millimeter, so that a space or openings 70 of four millimeters remain between the turns. Blown air is blown at at least one end 71 of the coil spring 69, e.g. B. in such a way that the end 71 is connected to a leading through the axle 72 of the counter perforating cylinder 21 blowing air line 73.
the axle journal 72 is provided by means of a known rotatable insertion 74, which is connected to a blown air source 76.
the rotary insertion 74 is by means of a flange 77 attached to the side frame 78 of the machine.
the counter bar 67 consists of a hard rubber-like, elastic material, for. B. plastic, such as polyester-polyol with a hardness of about 90 Shore A.
the function of the device for transverse perforation is as follows: during the production of the folder, the signatures rest on a working surface 88 of the counter bar 67 which extends the periphery of the counter perforating cylinder 21, so that the signatures are cross perforated between the perforating knife bar 3 and the counter bar 67, whereby a Distance m between the working surface 88 and a deepest point 89 of the cross section of the coil spring 69 is less than the depth of penetration of the individual perforating knives 8; 9; 36 into the counter bar 67.
the openings 70 of the support device, ie the coil spring 69 are opposite the working surface 88 of the counter bar 67 at a distance m.
the supporting device of the counter bar 67 consists of a tube 79 which has openings in the direction of the perforating knife bar 3 of the counter perforating cylinder 21 in the form of a continuous longitudinal slot 81 which extends over the entire length of the counter bar 67.
a longitudinal slot 81 it is also possible to provide a plurality of longitudinal slots spaced apart from one another and extending over the entire axial length of the counter-perforating cylinder 21 in such a way that the longitudinal slots each have the individual perforating knives 8; 9; 36 of the Perforating knife bar 3 of the counter perforating cylinder 21 correspond.
the support device of the counter bar 67 consists of a tube 83 with a plurality of slots 84 which are spaced apart in the axial direction (h) and extend in the circumferential direction of the tube 67.
the slot spacing h can be approximately a quarter of the axial length of the slot 84 ( Fig. 7).
the slots 84 can also be dimensioned in their axial length such that the individual perforating knives 8; 9; 36 correspond to the slots 84.
the support device of the counter bar 67 consists of rings 86 spaced apart from one another in the axial direction of the counter perforating cylinder 21, the inner diameter i of which corresponds to the diameter i of the axial bore 68 of the counter bar 67 (FIG. 8).
a thickness k of the rings 86 corresponds to approximately a quarter of the axial ring spacing, wherein a ring spacing also simultaneously represents an opening 87 between the rings 86, one for the action of the individual perforating knives 8; 36; 9 serving work surface 88 is opposite. It is also possible to connect the rings 86 in the axial direction to one another by means of two or three webs.
openings 81; 84; 87 can the individual perforating knives 8; 36; 9 can be adapted such that the individual perforating knife 8; 36; 9 with regard to their length and width, penetration into the interior of the openings 81; 84; 87 enable at a distance that is over a between the working surface 88 and the deepest point 89 of the cross section of the support device 79; 83; 86 located distance m goes, that is larger, z. B. 0.5 mm.
a counter bar 92 has a square cross section. Each of these circumferential, in the axial direction of the counter-perforating cylinder 21 extending work surfaces 88; 93; 94; 96 has at its perforation knife line 91 an equal distance from a longitudinal axis 97 of the support device 69 (FIG. 9).
