Definitions

  • the invention relates to a signature and a perforating knife for perforating signatures before folding according to the preambles of claims 1 to 6.
  • US Pat. No. 2,775,448 has disclosed two methods and devices for carrying them out, by means of which a perforation is first created in a signature and then folded along this perforation.
  • first method longitudinal slits are created along and on a fold line that are spaced apart from one another by the same length as the length of the slits.
  • second method slits are created which run transversely to the fold line and are evenly spaced from one another.
  • U.S. Patent 2,620,205 shows a multi-ply paper web having "H" shaped slots. These slots are located at the separation point between two signatures. They are used to hold a register finger of a web feed device. The paper web is held in the register by threading the "H" -shaped slot onto the register finger.
  • the longitudinal slots give a fold break exactly and In the event of a possible subsequent fold, avoid the formation of creases, especially in the vicinity of the subsequent fold. However, this only applies to thin-layer products. In the case of multilayer folded products, e.g. B. for phone book or magazine sections a pinch formation, especially towards the edge areas can not be avoided, because the between Longitudinal slots remaining uncut sections are wide. As a result, displacements of the two sides separated by the fold break, relative to one another, which are necessary as a result of a subsequent second fold running perpendicular to the first fold, cannot be compensated for.
  • the invention has for its object to provide signatures that are largely free of wrinkles along a provided folding line after folding, and to create a perforating knife for perforating signatures along a predetermined folding line, so that the perforated signature with this perforating knife after folding along the Fold line are largely free of creases.
  • the perforating teeth of the perforating knife can advantageously be regrinded, so that the total service life of the perforating knife is very long.
  • it is adjustable in height so that the perforating teeth of the perforating knife, which overhang the periphery of the cutting cylinder, can be set precisely to a predetermined dimension.
  • a two-part design of the perforating knife enables the two halves of the perforating knife to be replaced separately.
  • the perforating knife halves are identical and are therefore inexpensive to manufacture.
  • a folder of a rotary printing machine has u. a. a perforating cylinder 1.
  • the perforating cylinder 1 carries a knife bar 3 in a cylinder-wide pit 2.
  • the knife bar 3 has a receptacle 4 for a perforating knife 6.
  • Seen in the direction of rotation of the perforating cylinder 1, a spring-loaded hold-down device 7, 8 is provided in front of and behind the perforating knife 6.
  • the hold-down devices 7, 8 press a signature 9 against a counterperforation cylinder 11 and thus prevent the signature 9 from slipping during the perforation process.
  • the perforating knife 6 cooperates with an elastic counter bar 12 which is attached to the counter perforating cylinder 11.
  • the perforating knife 6 is made in two parts and consists of two thin-walled steel sheets 17, 18 (z. B. 1 mm) which are slightly wider than the signature 9.
  • the sheets 17, 18 are identical to one another and each with its rear side 19; 21 attached to each other in the cutter bar 3 that they complement each other in their mode of action to a single blade.
  • Each sheet 17; 18 has a plurality of perforating teeth 24 on an upper edge 23; 26 on.
  • the perforating teeth 24; 26 all have, except for one perforating tooth 24.1 arranged in the middle; 26.1, the same tooth width and are arranged at a distance from one another, so that in each case between two adjacent perforating teeth 24 and 24; 26 and 26 a tooth gap 27; 28 arises.
  • the perforating teeth 24.1, 26.1 arranged in the middle of each steel sheet 17, 18 are made somewhat wider than the rest
  • Perforating teeth 24, 26 This leaves no gap between the perforating teeth 24.1, 26.1 when the two perforating knife halves 6 are juxtaposed.
  • the base cutting edges 29, 30 of the perforating teeth 24, 24.1; 26, 26.1 lie on a common straight line 37.
  • the tooth gaps 27; 28 are somewhat wider than the perforating teeth 24; 26.
  • the arrangement of the perforating teeth 24; 26 and tooth gaps 27; 28 is selected such that a perforating tooth 24 covers a tooth gap 28 and a perforating tooth 26 covers a tooth gap 27 almost up to a small gap a (approx. 0.5-3 mm).
  • the gap a is the distance between the leg cutting edges 31, 32 of two immediately adjacent perforating teeth 24, 26.
  • Each perforating tooth 24; 26 is chisel-shaped on one side to the base cutting edge 29; 30 ground and each has two leg cutting edges 31; 32 on its inclined side flanks 33; 34 on.
  • ⁇ and ⁇ are of different sizes.
  • the cutting edges 29, 31; 30, 32 of the perforating teeth 24, 24.1; 26, 26.1 are designed in a "U" shape, the leg cutting edges 31, 32 of immediately adjacent perforating teeth 24, 26; 24.1, 26.1 are mutually arranged.
  • the base cutting edges 29, 30; 47; 59 all perforating teeth 24, 26, 24.1, 26.1; 45; 57 on or lie in the vicinity of the common straight line 37 and the two leg cutting edges 31, 32; 61 two immediately adjacent perforating teeth 24, 26; 24.1, 26.1; 57 are folded against each other by 180 o around the straight line 37 provided.
  • the perforating knife 6 On a lower edge 43, the perforating knife 6 has a plurality of recesses 44, by means of which it can be displaced vertically but not horizontally in the receptacle 4.
  • the perforating knife 6 is made in one piece.
  • the perforating knife 6 creates a perforation in a multilayer signature 9 such that the signature 9 has a plurality of mutually extending "U" -shaped perforations 35, 40 along or in the vicinity (for example ⁇ 0.2 mm) of the fold line 36. 41 has.
  • the base cuts 35, 35.1, 35.2; 51; 67 of all perforations 35, 40, 41; 51, 52; 67, 68 lie on or in the vicinity of the fold line 36 provided and the two leg cuts 40, 41; 68 of two immediately adjacent perforations 35, 40, 41; 67, 68 are each folded through 180 o around the intended fold line 36 in the signature level.
  • leg cutting edges 31; 32 of the perforating teeth 24; 26 produced leg cuts 40; 41

  • the perforating teeth 45 are each separated from one another by a tooth gap 54. Only two perforating teeth 45 each formed in the middle, in the area of an intended longitudinal fold 42, are arranged close together so that there is no distance a between the perforating teeth 45.

Between the thigh cutting edges 48 generated leg cuts 52 each have a small web 53, only between two base cuts 51 made in the signature center 42 no web 53 remains.
  • a perforating knife 56 has a multiplicity of perforating teeth 57 which are arranged next to one another at a distance a, in which the cutting edges 59, 61 of the perforating teeth 57 have a "lying crank” shape, which means that the one "Crank rod” corresponding basic cutting edges 59 lie on a common straight line 37 and that the "crank pins" corresponding leg cutting edges 61 of the perforating teeth 57 and the leg cutting edges 61 of two immediately adjacent perforating teeth 57 are mutually arranged.
