Definitions

  • the present invention relates to a folding apparatus for cutting a web printed by a web rotary press into sheets of predetermined size and folding the cut sheets.
  • a conventional web rotary press has a folding apparatus for cutting a printed, dried and cooled web into sheets of predetermined size and folding the cut sheets into halves along their path of travel or perpendicularly thereto.
  • the folding methods in the conventional folding apparatuses are: former folding for causing a former to fold a web into halves along its path of travel before the web is cut; single or double signature parallel folding for causing a folding cylinder to fold signatures into halves or quarter perpendicularly to their path of travel; and chopper cross folding for causing a chopper to hold parallel-folded signatures into halves along their path of travel.
  • each signature conveyed by chains abuts against a paper stop.
  • a plate-like chopper blade moves downward toward the center of the stopped signature and then into a gap between lower rollers, thereby folding the signature into halves.
  • the conventional chopper folding apparatus cannot perform high-speed folding at a speed exceeding a given maximum speed.
  • an overall speed of the printing press including a printing apparatus and a delivery apparatus must be decreased corresponding to the maximum speed of the chopper folding apparatus. This has prevented development of high-speed printing presses.
  • two pairs of signature conveying means and delivery means are arranged.
  • Printed and parallel-folded signatures are alternately fed to the two pairs of assemblies, and are folded with choppers at a relatively low speed.
  • the cross-folded signatures are then discharged.
  • a pair of speed reduction cylinders are brought into rolling contact with a gripper cylinder having a diameter twice that of each speed reduction cylinder.
  • the feed speed of each signature delivered from the gripper cylinder is reduced by each reduction cylinder and the signature is fed to upper or lower chopper folding path.
  • a folding apparatus for a web rotary press which folds signatures obtained by cutting a web by a combination of a cutting cylinder and a pin cylinder, comprising: a folding cylinder adapted to be in rolling contact with the pin cylinder located in an upstream thereof and having pins and insertion blades at a plurality of positions on an outer surface at equal angular intervals, the pins being alternate with the insertion blades; a gripper cylinder adapted to be in rolling contact with the folding cylinder, the gripper cylinder having a diameter substantially 1/1.5 times that of the folding cylinder and gripper plates which selectively correspond to the insertion blades upon rotation of the folding cylinder and the gripper cylinder; a speed reduction cylinder adapted to be in rolling contact with the gripper cylinder, rotated at a peripheral velocity lower than that of the gripper cylinder, and having first gripper units which selectively correspond to the gripper plates upon rotation of the gripper cylinder and the speed reduction cylinder;

Only the first signature 4B is delivered as a single signature, and the second and subsequent signatures are delivered as double signatures each.
  • the peripheral velocity of the speed reduction cylinder 19 and the transfer cylinders 23 and 25 is lower than that of the cutting cylinder 6 to the gripper cylinder 16, so that the feed speed of the signature fed to the chopper unit can be decreased. Even if the speed of the signatures fed from the cutting cylinder 6 to the gripper cylinder 16 is increased in accordance with the printing speed, the signatures can be fed at a speed lower than the printing speed. As a result, high chopper folding precision can be maintained, and the number of folded signatures obtained is the total number of signatures from the upper and lower chopper units, thereby guaranteeing productivity corresponding to the printing speed.
  • the folding apparatus for the web rotary press has: a folding cylinder with pins and insertion blades and in rolling contact with a pin cylinder; a gripper cylinder adapted to be in rolling contact with the folding cylinder and having a diameter 1/1.5 times that of the folding cylinder and gripper plates opposite to the insertion blades; a speed reduction cylinder adapted to be in rolling contact with the gripper cylinder, rotated at a peripheral velocity lower than that of the gripper cylinder and having gripper units; and a pair of upper and lower transfer cylinders each with two gripper units opposite to the surface of the speed reduction cylinder.
  • the signatures parallel-folded by the folding and gripper cylinders transferred to the speed reduction cylinder.
  • the signatures are alternately transferred from the speed reduction cylinder to the upper and lower transfer cylinders.
  • the parallel folding speed and the chopper capacity which correspond to a high printing speed can be maintained, and at the same time, the speed of signatures fed into the chopper units can be decreased, thereby improving productivity corresponding to high-speed printing and folding precision of the chopper units.
  • the conveyance speed of the signatures is decreased, they are firmly gripped by the corresponding gripper units. The trailing edge of each signature is released when the signature is delivered from the transfer cylinder. Therefore, signature misalignment can be minimized and folding precision is improved.
  • pattern assignment is considered, different patterns can be assigned to the upper and lower cylinders, thereby greatly facilitating the subsequent operation.
  • Single signature parallel folding can be easily switched to double signature parallel folding, and operability can be improved.
  • Signature cutting and signature overlaying are performed at different positions, thereby obtaining high cutting precision.
