Definitions

  • the invention relates to a folding pocket for pocket folding machines with a pocket upper part, with at least one sheet stop and with a pocket lower part, which has a lower inlet plate with a sheet guide surface and a guide edge facing the folding rollers.
  • the object on which the invention is based is now to design the folding pocket of the type mentioned at the outset in such a way that perfect folding guidance is ensured in the folding pocket even when thin sheets are folded.
  • the sheet guide surface has elevations which extend in the sheet running direction and parallel to each other, are narrow in their longitudinal direction, which rise with an arc leading inclination from the plane of the inlet plate, which one have such a distance from the leading edge that the sheet strikes the sheet guide surface in front of the elevations when it enters the folding pocket and is pulled off when the fold is formed over an exact edge, and which have such a height above the sheet guide surface and such a distance that one another Wave formation of the arch can be set transversely to its running direction with slight contact of the troughs with the arch guide surface.
  • the folding pocket designed according to the invention has the advantage that the sheet has essentially only line contacts with the lower inlet plate, so that the contact surface and thus the friction are greatly reduced, but an electrostatic discharge is possible.
  • the wave-shaped deformation of the incoming sheets increases their longitudinal stability, which is particularly advantageous in the case of thin papers running in the grain direction.
  • elevations are expediently formed without edges and rounded.
  • the distance between the elevations and the leading edge is usually 3 mm to 7 mm.
  • the elevations can be arranged side by side in pairs.
  • the distance between the elevations or pairs of elevations transverse to the sheet running direction is advantageously 10 mm to 50 mm.
  • a height of the elevations of 0.5 to 1.0 mm is preferred.
  • the length of the elevations is usually between 20 mm and 40 mm.
  • the elevation of the elevations from their leading edge side to their full height expediently takes place to 10 to 20% of their total longitudinal extent.
  • the narrow protrusions are usually 4 to 6 mm wide.
  • the production of the elevations is particularly simple if they are beads which are formed from the surface of the lower inlet plate opposite the sheet guiding surface.
  • FIG. 1 shows the inlet part of a folding pocket 6 with a sheet stop 7 and the associated folding rollers 3, 4 and 5. Furthermore, a sheet 2 entering the folding pocket 6 in the direction of arrow 1 is shown. Turn folding rollers 3, 4 and 5 thereby in the directions shown by arrows.
  • the folding pocket 6 has on its pocket bottom part a lower inlet plate 8 with a leading edge 9 facing the folding rollers 4 and 5. Elevations 10 are formed on the inlet plate 8.
  • the inlet plate 8 has a sheet guide surface 13 on which the elevations 10 are formed.
  • the elevations 10 extend in the direction of sheet travel (arrow 1) and are arranged parallel to one another at intervals 17.
  • the elevations 10 have a width 18 which is small compared to their longitudinal extent, i.e. the elevations 10 are relatively narrow. They rise with an incline leading from the arch guide surface 13 over the area 15 to the height 14 and go back into the arch guide surface 13 in the end region of the inlet plate 8 opposite the guide edge 9.
  • the elevations 10 have a distance 12 to the leading edge 9, which is dimensioned such that the sheet 2 strikes the sheet guide surface 13 before the elevation 10 when it enters the folding pocket and, when the sheet is pulled off between the folding rollers 4 and 5, is pulled off via an exact Edge, ie the leading edge 9 is guaranteed.
  • the arch 2 Due to the height 14 and the spacings 17 of the mutually parallel elevations 10, the arch 2 forms waves 11 (FIG. 3), which essentially results in line contact between the arch 2 and the inlet plate 8 on the elevations 10 and in the troughs 16 with the arch guide surface 13 sets.
