Definitions

  • the invention relates to a wheel folder according to the preamble of claim I.
  • Folders have long been known in a wide variety of designs.
  • a wheel folding apparatus which has a cutting cylinder and a puncture and rubber strip cylinder interacting with the cutting cylinder.
  • the rubber strip cylinder works with a collecting cylinder and this, together with an intermediate transfer cylinder, works with two further folding knife cylinders, each of which is assigned two folding rollers.
  • a disadvantage of the subject of CH-PS 4 78 666 is that an additional transfer cylinder, e.g. between the collecting cylinder and the folding knife cylinder is required.
  • all of the signatures cut between a cutting and rubber cylinder are cut to the same length, which, particularly in the case of collective production, leads to the fact that the inner layers protrude beyond the outer layers after folding.
  • a paper strand entering the folder has the same speed as the peripheral speed of the collecting cylinder. This measure can disadvantageously obstruct the trailing edges of the signatures collected on the collecting cylinder with the leading edges of the signatures to be delivered by the collecting cylinder.
  • the invention has for its object to provide a gear folder, in which the cutting and folding forces act on different cylinders, in particular in the case of collective production to ensure that two consecutively cut signatures have different lengths and that the paper web strand tension is not due to collecting processes or can be affected by the production of thick folded products.
  • a wheel folding cylinder can be used, in which the folding knives do not need to be arranged on a separate folding knife carrier rotating within a gripper and pinpoint cylinder, but can be stored in side plates of folding unit cylinders which are positively connected to the cylinder shaft. Longer folding knives and thus folding rollers with larger diameters can be used, which reduces the folding forces.
  • Fig. 1 is a schematic side view of the folder according to the invention, without a front side frame.
  • one or more paper webs 1 pass via longitudinal folding funnels 2 directly or past the longitudinal folding funnels 2 by means of guide rollers 3, between electrically or mechanically driven pull rollers 4, 6, 7.
  • the partial paper web strands 8, 9 or cut open and longitudinally folded by means of longitudinal folding funnels 2 Paper layers brought together by means of turning bars run in via the pull roller 7 between a cutting cylinder 11 with two cutting knives 12, 13 and a puncture and groove bar cylinder 14.
  • the two cutting knives 12, 13 lie opposite one another, but in the case of collective production on a straight line at a distance from the diameter of the cutting cylinder 11, so that alternately different lengths of signatures are cut off from the individual or combined partial paper web strands 8, 9 and from both controllable point sets 16, 17 are taken over alternately.
  • the cutting knives 12, 13 lie on the straight line along the diameter of the cutting cylinder 11.
  • the puncture and groove bar cylinder 14 has two controllable puncture sets 16, 17 and two counter-cutting groove bars.
  • the number of punctures 16, 17 and counter-cutting groove strips can, however, just as with the cutting cylinder 11, the cutting knives 12, 13, be an integral multiple of two.
  • the puncture and groove bar cylinder 14 is equipped with a device for optional or automatic enlargement or reduction of the cylinder diameter. As a result, the string voltage is set and kept constant.
  • a collecting cylinder 18 preferably interacts with the puncture and groove bar cylinder 14, preferably with three controllable point sets 19, 21, 22 arranged at regular intervals from one another.
  • the signatures are delivered from the collecting cylinder 18 to the gripper sets 24, 26, 27 of a two-part folding knife cylinder 23 consisting of a jacket and a folding knife carrier.
  • the folding knife carrier three, known wheel folding knives 28, 29, 31 are mounted. It is supported on a drive shaft of the folding knife cylinder 23 and is positively connected to it.
  • the wheel folding blades 28, 29, 31 each rotate below a slotted circular jacket of the folding blade cylinder 23, which is also supported on the drive shaft of the folding blade cylinder 23, and press the Signa into it doors in driven folding rollers 32, 33 through the slots in the jacket.
  • Three controllable gripper sets 24, 26, 27 arranged at the same distance from one another are provided on the jacket of the folding knife cylinder 23. If the signature thickness changes, the part of the folding knife cylinder 23 carrying the wheel rebate blades 28, 29, 31 is shifted in a circumferential direction in or against the direction of rotation by means of a gear which carries the gripper sets 24, 26, 27.
  • the centers of the drive shafts of the wheel folding knife 28, 29, 31 run on a circle, the center of which lies on the center of the drive shaft of the folding knife cylinder 23.
  • controllable point sets can also be used instead of the gripper sets 24, 26, 27.
  • the invention is also not limited to the use of 2/2-cutting and puncturing and groove bar cylinders 14, folding blade cylinders 23 with three gripper sets and three gear rebate blades 28, 29, 31. Rather, e.g. 1/2 cutting cylinders with a cutting knife 12, folding knife cylinder 23 and two gripper or point sets and correspondingly two wheel rebate knives etc. can also be used.
  • the collecting cylinder could also e.g. be a 5/2 cylinder.
