Definitions

  • the invention relates to a device for the production of at least once cross-folded, trimmed parallel to the transverse fold products, which are either designed according to the transverse fold or provided with a further fold designed as a longitudinal fold, with a folding jaw cylinder interacting with a folding knife cylinder, a cantilever star and one Folders that can be optionally loaded and that lead to a folding sword are arranged downstream.
  • a separate trimming unit can advantageously be omitted here, which has a positive effect on the construction effort and the achievable production speed and thus on the overall economy.
  • the lifting tongues associated with the delivery star which engage in a manner known per se between the folding products to be lifted and the cylinder circumference of the jaw cylinder, can be easily swung out so far during the passage of the scissor-cutting knives protruding over the circumference of the jaw cylinder that the scissor-cutting knives can pass undisturbed there, since the ends of the products to be lifted here lie practically freely on the jaw cylinder.
  • the scissor cut knife of the knife carrier cylinder is simply passivated.
  • the folder shown in Fig. 1 consists in a manner known per se from a folding jaw cylinder 2 provided with three folding jaws 1 on the circumference, against which a folding knife cylinder 4 is provided with two folding blades 3, the folding blade 3 of which is used to produce a transverse fold in the folding jaws Knock in 1 of the jaw cylinder.
  • the folding knife cylinder 4 carries in the area between the two folding knives 3 two cutter bars 6 each provided with a cutting groove 5 and adjacent puncture needle bars 7 with puncture needles 8 effective behind the cutter bars 6 in the direction of rotation.
  • the diameter of the knife carrier cylinder 15 provided with a scissor cut knife 16 corresponds to one third of the effective diameter of the jaw cylinder 2, so that the knife cutter 16 cooperates with all the scissor knife blades 14 of the jaw cylinder 2 at the same peripheral speed of the jaw cylinder 2 and knife carrier cylinder 15.
  • the knife carrier cylinder 15 is provided with puncture needles 17 which are arranged behind its scissors-cutting knife 16 in the direction of rotation and which take up the strips cut off when the scissors are cut.
  • the appropriately fixed puncture needles 17 can each be assigned a support 18 consisting of a foamed material strip.
  • the knife carrier cylinder 15 is simply sucked off on a circumferential area downstream of the scissor interface in order to remove the cut strips.
  • the knife carrier cylinder 15 always assumes the same reproducible angular position with respect to the jaw cylinder when the clutch is inserted.
  • the knife carrier cylinder 15 can expediently be locked in the direction of rotation, so that it cannot be carried along by bearing friction or the like.
  • a blocking brake or a blocking pin or the like (not shown here in more detail) can simply be provided.
  • a flap 24 which is pivotably mounted on the machine frame side is provided in the area of the delivery star 21, which travels under the products to be lifted out with lifting tongues 25 engaging in the folding flaps 1.
  • a pressure roller 32 which is assigned to the folding jaw cylinder 2 and is arranged between the band guide 23 and the delivery star 21, is provided to ensure safe transport of the products released by the folding jaw 1 passing through the lifting tongues 25.
  • the scissor cut knife 14 of the jaw cylinder 2 should, as has already been indicated above, be firmly mounted.
  • the flap 24 is therefore controlled in such a way that the lifting tongues 25 pass over the scissors-cutting knives 14 projecting over the circumference of the folding-flap cylinder 2 as they pass.
  • the pressure roller 32 is provided with a flat 33 for this purpose, which faces the folding jaw cylinder 2 during the passage of the scissor cut knife 14.
  • the pressure roller 32 is driven in such a way that the folding cylinder circumferential speed results in the area outside the flattened area 33.
  • the pressure roller 32 can simply be attached to a spindle with the Flat 33 containing cams exist. In the rest position with the tape guide activated, the pressure roller 32 can simply be set so that the flat 33 faces the folding jaw cylinder.
  • the drive is therefore expediently via a clear clutch. When the clutch is disengaged, the rest position is appropriately blocked in the direction of rotation.
