Definitions

  • the invention relates to a method for folding sheets according to claim 1 and a folding machine for folding sheets according to the preamble of claim 5.
  • the object of the present invention is therefore to describe a folding method and to provide a folding machine, which overcomes the disadvantages of the prior art and does not require any structural modifications of existing folding units.
  • the invention relates to a method for the shingled folding of sheet-shaped elements, in particular of printed sheets of paper, cardboard and the like in a folding machine.
  • the folding machine has at least one folding station with at least one folding unit.
  • the arcuate elements are fed in a transport direction with its front edge ahead with a Unterschuppung the folding station.
  • the Unterschuppung corresponds according to the invention at most the first fold length.
  • a fold break is produced transversely to the transport direction in a respective arcuate element, and the arcuate elements are folded down with a first fold length, ie the leading edge of a respective arcuate element is deposited on its underside.
  • the fold is such that the distance between the stored front edge of a first arcuate element and the front edge of a subsequent not yet folded arcuate element is greater than or equal to zero. That is, the leading edges are spaced from each other even after the first fold or lie in the limit case to each other.
  • the leading edge of a first arcuate element is thus located in the transport direction downstream of the leading edge of a subsequent not yet folded arcuate element. This is ensures that a first incoming arcuate element and a subsequent incoming arcuate element does not meet
  • the underschuppte folding according to the invention can be carried out in a Taschenfalzstation or a Parallelhistfalzstation.
  • the Parallelhistfalzstation has a lower and acting from below folding blade.
  • the folded product produced in this case can be further processed by further folding, whether in subsequent folding units of the same folding station and / or in subsequent folding stations, by further folding.
  • the invention also relates to a folding machine for folding sheet-like elements such as sheets of paper, cardboard and the like with at least a first folding station and a flaker.
  • the first folding station has at least one folding unit.
  • the flake feeder serves for the shallow feeding of arcuate elements via an alignment table to the first folding station in a first transport direction.
  • the shed feeder has a device for separating the arcuate elements and a suction device adjustable in and counter to the first transport direction.
  • the degree of Unterschuppung the arcuate elements can be adjusted by adjusting the suction device.
  • the suction device is operated clocked and by a change in the clock, the Unterschuppungsgrad is changeable.
  • the timing can be achieved in a manner known to those skilled in the art by a pulsed air supply and / or by a lifting movement of the suction device.
  • the device for separating the arcuate elements is a suction head with lifting suction and blowing air assistance.
  • the suction device can advantageously be designed as a drag sucker or as a suction wheel.
  • this transport means has to transport the arcuate elements, such as conveyor belts or Schrägrollentician.
  • the feeder, the at least one folding station and the means of transport are controlled in an advantageous manner by a common control unit.
  • the first folding station is followed by a second folding station.
  • This can have pocket folders or Schwertfalzwerke.
  • at least one folding station is preceded by a device for applying adhesive to the products.
  • at least one folding station is arranged downstream of a device for trimming the products. By the device for applying adhesive and the device for trimming the products, it is possible in an advantageous manner to produce small books, so-called booklets, from the sheets.
  • at least one folding station is arranged downstream of a device for pressing the products. By squeezing the products can be prevented bulging of the products in an advantageous manner.
  • Fig. 1a are two arcuate elements, here two sheets 7a, 7b shown, which are transported in the transport direction T by a feeder 2 to a first folding station.
  • the distance b between the first sheet 7a and the second sheet 7b is usually in the range of 5 to 8 cm.
  • the sheets 7a and 7b are folded three times, whereby sheet parts arise with the same dimension.
  • the arch parts are in Fig. 1a indicated by the folds in the first folding station 3, a respective sheet 7a, 7b divided into four equal parts.
  • Fig. 1b are two sheets 7a, 7b shown, which are transported by a feeder 2 coming in the direction of transport T to a first folding station 3.
  • the sheets 7a and 7b are transported underfoot.
  • the downstream end of the sheet 7b is covered by the first sheet 7a.
  • Three folds are generated so that a respective sheet 7a, 7b is divided into four equal parts of the sheet.
  • the Unterschuppung d is one quarter of the length of the bow 7a, 7b.
  • spaced transport of the two sheets 7a and 7b was for the underschuppten transport according to Fig.
  • the second sheet 7b is displaced in the transporting direction T by the sum of the sheet spacing b and the shingling d.
  • the sheets 7a, 7b have to travel a smaller distance. Ie. at constant machine speed, ie transport speed, more sheets can be processed to finished folded products and the output of the folding machine 1 can be increased.
  • the application of the folding machine 1 can be maintained and the transport speed of the sheets 7a, 7b can be reduced, especially if it is difficult to process material, which requires a lower transport speed to ensure a high quality of the products.
  • FIG. 2a to 2c is shown how the underschuppten sheet 7a, 7b are folded in the pocket folders of the first folding station 3.
  • a first snapshot is shown.
  • the sheets 7a, 7b are supplied from a feeder 2 via a feed table 9 in the transport direction T of the first folding station 3.
  • the sheets 7a, 7b have a Unterschuppung d.
  • the first sheet 7a has already been transported past the first upper folding pocket 11 into the second folding folder 11 located below.
  • a sheet diverter 13 prevents the entry of the first sheet 7a in the first folding pocket 11.
  • the pocket stop 12 of the second folding pocket 11 has been set to the inlet length (folding length) 14.
  • the inlet length 14 corresponds to one third of the length of the sheets 7a, 7b.
  • Fig. 2b a second snapshot is shown.
  • the first sheet 7a has already left the second folding pocket 11, wherein a first fold break was produced by the folding rollers 15.
  • the first sheet 7a is already in the third, upwardly located folding pocket 11.
  • the second sheet 7b is running straight into the second folding pocket located at the bottom.
  • the setting of the inlet lengths 14 of the folding pockets 11 and the dipping with the size d ensures that the sheets 7a and 7b do not meet in the first folding station 3 in such a way that relative speeds occur between the first sheet 7a and the second sheet 7b.
  • the front edge 30a of the first sheet 7a is deposited by the fold so that it has a distance greater than zero to the front edge 30b of the subsequent second sheet 7b.
  • Fig. 2c represents a third snapshot.
  • the first sheet 7a is already folded and is discharged from the first folding station 3.
  • a first fold break has just been generated by the folding rollers 15.
  • the first arc 7a and the second arc 7b do not meet and there is no relative movement between the two sheets 7a, 7b.
