Definitions

  • the invention relates to a device for cross perforating signatures according to the preamble of claim 1.
  • EP 03 07 891 B1 has disclosed a perforating knife for perforating signatures before folding, the perforating knife having a large number of perforating teeth arranged next to one another at a distance.
  • the cutting edges of the perforating teeth are U-shaped, so that the basic cutting edges of the perforating teeth lie on a common straight line, the legs of immediately adjacent perforating teeth being mutually arranged.
  • This perforating knife can be replaced completely.
  • the invention has for its object to provide a perforating knife for a perforating device for transverse perforation of signatures, in which the entire perforating knife bar does not have to be replaced after damage to a perforating tooth.
  • the invention has the following advantages in particular: the rapid interchangeability of the individual perforating knives increases the service life of the perforating knife bar.
  • the individual perforating knives are components that can be easily manufactured as standard. Furthermore, with a variation in the distances between the individual perforating knives, i. H. by varying the tooth gaps and thus the length of the webs, it is possible that the perforating knife bar can be adapted to both the thickness and the grammage of the signatures.
  • the perforating knife bar composed of the individual perforating knives according to the invention is suitable for forming a second longitudinal fold.
  • 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.
  • a medium single perforating knife 43 in several parts, e.g. B. from three parts, the parts of which are each separately displaceable or can be arranged in a row (FIG. 7), namely with a middle straight part 44 and a first outer straight part 46 with a first part 37 angled at an angle alpha and a second outer straight part 47 with a part 38 angled at an angle alpha, as already described for the central single perforating knife 36.
  • the straight parts 44; 46; 47 are arranged at a distance g from each other which corresponds less, ie up to 0.8 times the distance a between the individual perforating knives 8 or 9.
  • a single perforating knife designated overall by 49, has a straight perforating part 51 with at its two ends 14; 16 located, angled at an angle alpha perforating parts 52; 53.
  • a holding part 54 runs parallel and cohesively to the straight perforating part 51 with a second perforating part 56, which is also angled at an angle alpha and runs parallel and at a distance of 0.5 times a length l from the angled perforating part 52.
  • 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 the aforementioned single perforating knives 8; 9.
  • All angled perforating parts 52; 53; 56 point both in the direction of the plane 11 bisecting the length of the cylinder and in the direction of rotation C of the perforating cylinder 1.
  • These individual perforating knives 49 each have a right-hand and left-hand version, with softer the individual perforating knives with their angled perforating parts each in the direction of rotation C and in the direction of the cylinder bisecting plane 11 point and a single perforating knife analogous to the individual perforating knife 36 is arranged in the center.
  • This type of individual perforating knives 49 with the shortened angled, perforating parts are used in a spaced manner, advantageously used in particular for signatures with a relatively small number of up to 48 pages, in which the short angled, perforating parts a "short trimming" is achieved (Fig. 7).
  • a single perforating knife designated overall by 57, is formed in several parts and consists of two perforating angle parts 58 spaced apart from one another at a distance g (analogous to single perforating knife 43); 59, with their respective straight perforating parts 61; pointing in the axial direction of the perforating cylinder 1; 62 are directed towards one another, while the angled, perforating parts with the angle alpha in each case in the direction of rotation C of the perforating cylinder 1 and in the direction of the plane 11 bisecting the length of the cylinder with 63; 64 are designated. It is also possible to determine the distance g between the two angular parts 58; 59 to zero, so that a single perforating knife 8 or 9 is then formed in the arrangement.
  • the above-described single perforating knife e.g. B. 8; 36; 9 (Fig. 2) are with their straight perforating parts, for. B. 13 at a distance a between the vertical T leg 7 of the profile bar 4 and the terminal block 31, so that a perforating knife bar 3 is formed (Fig. 1 and 2).
  • the adjustable single perforating knives 8; 36; 9 of the perforating knife bar 3 act against one in a cylinder pit 66 of the counter perforating cylinder 21 attached elastic counter bar, labeled 67 in total.
  • 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 bore 68 extending in the axial direction to the counter-perforating cylinder 21, in which a cylindrical helical spring 69 extends over the entire length, the outer diameter of which rests on the diameter of the bore 68 (FIG . 1 and 9).
  • 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. Blown air is blown at at least one end 71 of the coil spring 69, e.g. B.
  • axle journal 72 is provided by means of a known rotatable insertion 74, which is connected to a blown air source 76.
  • the rotary insert 74 is fastened to the side frame 78 of the machine by means of a flange 77.
  • 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 are perforated transversely between the perforating knife bar 3 and the counter bar 76, the cutting edges, e.g. B. 22, 23, 24 of the individual perforating knife, for. B. 8, 36, 9 not only penetrate the paper webs of the signature, but at the same time penetrate beyond their theoretical effective diameter into the surface of the elastic counter bar 67 until they end just before the clear diameter of the bore 68.
