Definitions

  • the invention relates to a method and an apparatus for producing folded printed products.
  • the invention now aims to provide a method and an apparatus for producing folded printed products for use in sheet-fed printing presses, in particular in sheet-fed and reverse printing sheet-fed printing presses, which ensure high cost-effectiveness of the printing press by dispensing ready-to-ship printed products enable.
  • the method according to the invention is characterized in that the printing sheet leaving a sheet-fed printing press is guided in the direct connection to the printing machine between folding cylinders with cooperating folding knives and folding flaps which can be adjusted over the cylinder circumference, and is then folded one or more times, whereupon the cross-folded printed sheet transversely to its direction of travel cut its rear transverse edge and then by cutting longitudinally into individual side by side lying printed products is divided, which may then be stacked.
  • a device intended for carrying out this method which is equipped with folding cylinders, has the features according to the invention that a takeover cylinder with grippers is provided for direct connection to a sheet-fed printing press, which is equipped with a folding knife which is infinitely adjustable in relation to the grippers in the cylinder circumferential direction, and that several folding cylinders are connected, each of which has a folding flap and a folding knife, which are continuously adjustable in the cylinder circumferential direction, that the folding cylinders have a cutting device equipped with an adjustable system for cutting the folded printing sheet in the transverse direction and following this cutting device, at least one crosswise cutting device adjustable to the running direction for dividing the folded printed sheet into individual print products lying next to one another and, if appropriate, a forklift downstream for collecting and transporting these printed products s ind.
  • This training ensures a rational and cost-saving treatment of the printed products after the printing process in sheet-fed printing machines which do not print on endless print carriers but on different-sized sheets, because the printed products are ready for dispatch, i.e. leave in the counted and stacked state and the previously required intermediate stacking and subsequent separate folding and cutting processes are no longer necessary.
  • the invention is particularly suitable for multi-color perfecting and offset printing presses, as described in European patent application 82890154.6 dated October 25, 1982.
  • the device shown is particularly suitable for single-sheet and multi-color printing.
  • the printed sheet B is delivered from a delivery drum 1 to a takeover cylinder 2 which is driven in the direct gripper closure in a ratio of 1: 1 and has the same circumference.
  • a folding knife 7 is provided on the take-over cylinder 2 and is infinitely adjustable in the cylinder circumferential direction relative to grippers 6, as is indicated by the dashed arrows.
  • the takeover cylinder 2 is also a 1: 1 driven folding jaw and folding knife cylinder 3 so that the sheet B is pressed in the extreme case even over half its length from the folding knife 7 into a cylinder 3 arranged, continuously adjustable in the cylinder circumferential folding flap 8 can be so that the grippers 6 are free in time for the takeover of the subsequent sheet. In this way, a first transverse fold is formed in the printed sheet B.
  • the cylinder 3 which is provided with a folding knife 9 which is infinitely adjustable over the cylinder circumference, leads the printed sheet B folded and held by the folding flap 8 in the circumferential direction beyond that point at which the circumference of the cylinder 3 is closest to a downstream cylinder 4 .
  • the adjustable folding knife 9 then presses at this point to be folded for the second time, the printed sheet B into an adjustable folding flap 10 of the cylinder 4.
  • the cylinder 4 After opening the folding flap 8, the cylinder 4 has taken over the sheet B, which has now been folded twice, and feeds the sheet held by the folding flap 10 to a further traveling cylinder 5 .
  • a folding knife 11 of the cylinder 4 presses the sheet 13 into a folding flap 12 of the cylinder 5 at the point at which folding is to take place for the third time.
  • the folding process explained above can be repeated as many times as interacting folding jaw and folding knife cylinders 5a, 5b etc. are present.
  • the printed sheet then has, for example, the designation designated 27 in FIG. 3a.
  • the printed sheet can also be provided with a zigzag fold, as shown in FIG. 3b, where the folded printed sheet is designated by 28.
  • the finished cross-folded printed sheet B is placed on a conveyor belt 16 by the last cylinder or pair of cylinders by means of lowerable deflectors 14 or 15.
  • the deflectors 14, 15 prevent unintentional entrainment of the folded printed sheet B when the last folding flap is opened by detaching the sheet from the folding flap.
  • the folded printed sheet B is transferred under a guillotine shear 18 to another conveyor belt 17 which leads the folded printed sheet B to a stop 19 which can be adjusted and raised in the direction of the arrows.
  • the guillotine shears 18 cuts off the gripper edge or the rear edge zone of the folded printed sheet. If it is desired to achieve a two-ply or multi-ply product via the zigzag fold, the rear folded printed sheet edge, ie the left folded edge in FIG. 3b, is also cut away, so that only products folded on the back remain.
  • the folded and cut in the transverse direction cut sheet B after lifting the stop 19 from the conveyor belt 17 divided into several individual belts in the transverse direction (see FIG. 2) and with the aid of inlet rollers 21 shown in FIG. 1, circular knife 22 laterally displaceable with associated counter knives fed, which slit the cross-folded printed sheet B to the required extent and thereby divide in the transverse direction into individual print products lying next to each other.
  • the conveyor belt 17 guides the printed products 26 to a rotating forklift 23 with systems adjustable in the direction of the arrows, the width of which corresponds to the machine width.
  • the stacked printed products 26, which transport the stacks to the left, are transferred from the stacker 23 next to one another.
  • the conveyor belts 24 can be swiveled up and down in the direction of the arrows around the right deflection roller, so that after the conveyor belts have been lowered onto the belts, supports 25, e.g. Rollers are set down, through which the stacks are transported to the right or left side of the machine.
