  • a folder of a rotary printing machine has u. a. a perforating cylinder 1.
  • the perforating cylinder 1 carries a total in a cylinder-wide pit 2 perforated knife bar marked with 3.
  • the Perforating knife bar 3 has a form-fitting, z. B. connected to the bottom of the pit 2 by screws profile strip 4 extending in the axial direction, approximately in the form of a T rotated by 180 °. At the end 6 of the vertical, d. H.
  • Perforating cylinder 1 itself in the radial direction of the Perforating cylinder 1 extending leg 7, is supported in particular on an end face of the end 6 a right with a total of 8 and 9 respectively or to the left of a plane bisecting the perforating cylinder 11 arranged single perforating knife, which will be described in more detail below.
  • Each individual perforating knife 8; 9 shows one congruent with a future cross fold line 12 extending straight perforating part 13 (hereinafter referred to as a straight part) with a Width b and a height h.
  • both ends 14; 16 straight part 8; 9 extends in each case angled perforating part 17; 18 (hereinafter referred to as an angled part) with a length l and a height e.
  • Both angled parts 17; 18 are in an angle alpha, e.g. B. 45 ° to the straight part 13 angled so that the free ends of the angled Parts 17; 18 both in the direction of cylinder bisecting plane 11 as well simultaneously 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 as well straight part 13 of the single perforating knife 8; 9 instructions their side facing a counter perforating cylinder 21 cutting edges 22; 23 or a cutting edge 24 on.
  • the cutting edges 22 to 24 can each have one have one-sided bevel and also a finely toothed cutting edge 22 to 24 (Fig. 4 to 6).
  • a lower height e of the angled parts 17; 18 compared to the height h of the straight part 13 can the undersides 26; 27 of the angled parts 17; 18 on the end 6 of the vertical T-leg 7 support, while this by the amount h minus e protruding end or tongues 28 of the straight part 13 one long side of the vertical T-leg 7 abuts and by means of a parallel and in the axial direction to the vertical T-leg 7 extending terminal block 31, e.g. B. is clamped by means of screws.
  • the individual perforating knife 8; 9 individually in one Distance a, d. H. one tooth gap each, which one so-called bridge between two cuts in the signature 19 corresponds to be spaced apart.
  • the Distance a can be between two and eight millimeters lie.
  • the individual perforating knife 8; 9; 36, 43 can made of folded steel sheet with a thickness d, z. B. exist between 0.5 and 1.5 millimeters.
  • the Single perforating knife 8; 9 are each in one piece trained and can be symmetrical or asymmetrical plane 11 bisecting the cylinder length.
  • An asymmetrical arrangement of the individual perforating knives 8th; 9 (Fig. 2 and 3) has multilayered perforation Signatures 19, e.g. B.
  • a medium single perforating knife 43 multi-part e.g. B. from three parts to provide Parts can be moved separately or are arranged in a row (FIG. 7), namely with a middle straight part 44 and a first outer straight part 46 with an angled alpha angled first part 37 and a second outer straight part 47 with an angled at an angle alpha Part 38, as in the middle single perforating knife 36 already described.
  • the straight parts 44; 46; 47 are each arranged at a distance g from each other less, d. H. up to 0.8 times the distance a between the Individual perforating knives 8 or 9 corresponds.
  • a total of 49 individual perforating knives a straight perforating part 51 with on his both ends 14; 16 located in the angle Alpha angled perforating parts 52; 53.
  • runs parallel and cohesively to the straight perforating part 51 still a holding part 54 with a second also angled at the angle alpha perforating part 56, which is parallel and at a distance of 0.5 times a length l to the angled one perforating part 52 runs.
  • the length of the angled parts 52; 53; 56 is also about 0.5 times a length l of the angled parts 17; 18 of already mentioned single perforating knife 8; 9.
  • All angled perforating parts 52; 53; 56 points both in the direction of the plane bisecting the cylinder length 11 and in the direction of rotation C of Perforating cylinder 1.
  • This single perforating knife 49 consist of a right and left version, where the individual perforating knives with their angled perforating parts each in Direction of rotation C and in the direction of have cylinder-bisecting plane 11 and in the middle for Single perforation knife 36 analog single perforation knife is arranged.
  • This type of single perforating knife 49 with the shortened angled, perforating parts are advantageously spaced in a row especially for signatures with a relatively low one Number up to 48 pages applied, with which the short angled, perforating parts a "short Trimming "is achieved (Fig. 7).
  • the counter bar 67 can have a rectangular, in particular a square cross section with a in the axial direction of the counter-perforating cylinder 21 have extending bore 68, in which over the entire length is a cylindrical coil spring 69 extends, which with its outer diameter on Diameter of the bore 68 is present (Fig. 1 and 9).
  • This Coil spring 69 has a length that is greater than the product of the number of turns and the wire diameter the coil spring 69 so that the turns of the Coil spring 69 do not lie against each other. At least One end 71 of the coil spring 69 is blown air blown in, e.g. B.
  • journal 72 by means of a known rotatable Introduction 74 provided with a blown air source 76 communicates.
  • the rotary insertion 74 is by means of a flange 77 on the side frame 78 of the machine attached.
  • the counter bar 67 consists of a Hartgummiartirgen, elastic material, e.g. B. Plastic, such as polyester-polyol with a hardness of about 90 Shore A.
  • the function of the cross perforating device is like follows: during the production of the folder the signatures between the perforating knife bar 3 and the counter bar 76 transversely perforated, the Cutting edges, e.g. B. 22, 23, 24 of Single perforating knife, e.g. B. 8, 36, 9 not only that Penetrate paper webs of the signature, but simultaneously over their theoretical effective diameter out into the surface of the elastic counter bar 67 penetrate until it is just before the light End diameter of hole 68. Because of the permanent Penetration of the cutting edges 22, 23, 24 of the Single perforating knife 8, 36, 9 in the counter bar 67 at every cylinder revolution becomes the missing piece between the depth of penetration of the cutting edges 22, 23, 24 and the worked up clear diameter of bore 68, d. H.
