  • control and / or logic units 15, 43 and / or 46 may be spatially separated from each other, designed as a structural unit with separate sub-processes, or even integrated as sub-processes in the machine control 06.
  • Fig. 6 shows in a schematic section as a further example of a strand processing system according to the invention a folding apparatus 01 ', which is designed for the simultaneous processing of two strands 02, 02'.
  • a folding apparatus 01 ' On the paths of the strands 02, 02 'are arranged in order: a pair of catch rollers or a pull group 19 or 19', which serve a predetermined tension of the strands 02, 02 'at an upstream of them, in FIG.
  • a register-matching Kappvortechnisch 08, 08 ', an emergency stop Kappvortechnik 09, 09' and other train groups 21, 21 ' To maintain a former not shown upright, a register-matching Kappvorraum 08, 08 ', an emergency stop Kappvortechnik 09, 09' and other train groups 21, 21 '.
  • the strand 02 reaches the surface of a transport cylinder 22, which may be designed as a gripper or NOTEurzylinder, downstream of the second train group 21, in the amount of a cutting gap 62 between the transport cylinder 22 and a first knife cylinder 26, like the corresponding knife cylinder Fig. 1 together with the transport cylinder 22 forms a cross-cutting device 03 for severing the strand 02 in each case between two product sections.
  • a second cutting cylinder 26 ' which is part of a second transverse cutting device 03', which decomposes the second strand 02 'into product sections in a corresponding manner, is arranged offset by exactly one product section length relative to the cutting cylinder 26 on the circumference of the transport cylinder 22.
  • the strand 02 is first synchronized to the phase position of the Puncture cylinder 22 so capped, that an incomplete product portion remains on the capped strand 02, whose length is preferably only slightly smaller than that of a complete product section, for example about 90% of its length.
  • this incomplete product portion hits the puncturing cylinder 22, it does not contact its puncturing needles when they are extended out of the puncturing cylinder 22 just before passing the cutting gap 62 between the cylinders 22,26.
  • the leading incomplete product section thus passes through the cutting gap 62 without being punctured. He is clamped after passing through the cutting gap 62 only by a follower roller or belts against the surface of the Puncture cylinder 22.
  • the operation of the capping device 08 'on the path of the strand 02' is synchronized with that of the capping device 08 so that a leading edge of the strand 02 'obtained by the capping coincides with the leading edge of the strand 02 on the surface of the pinuning cylinder 22. While this is done and the string 02 is clamped to the surface of the pinhole cylinder 22, a second product portion of the string 02 following the incomplete product portion is punctured just before it enters the cutting gap 62 between the cylinders 22, 26 by the extending puncturing needles. After puncturing, the cutting cylinder 26 separates the second product portion from the first, incomplete product portion.
  • the entire second product section is dotted prior to cutting, so that the two incomplete product sections after the Passing the second cutting gap are unguided and can fall down, whereas the following complete product sections of both strands are securely punctured and further conveyed in a conventional, not further described manner on the cylinder 22 along, during the transfer to a jaw cylinder 31 transversely folded and finally from this a paddle wheel 63 are output.
  • the capping devices 08, 08 'could also be synchronized with the puncturing cylinder 22 in such a way that one of the strands 02, 02' or both are each exactly cut off at the boundary between two product sections. However, this would have no advantages for the operation of the device. While the leading edge of each capped strand on the puncturing cylinder 22 would then each contact the puncturing needles, the puncturing needles would not be able to pierce that edge, but rather would urge the edge radially outward, respectively at the entrance of the cutting gap 62, 62 'could lead to stoppers.
  • the transport cylinder 22 is designed as a gripper cylinder, its operation does not differ from that of the Puncture cylinder, provided that the Kappvor512en 08, 08 'respectively incomplete first product sections on the strands 02, 02' produce.
  • the incomplete product sections can not be grasped by the grippers and therefore fall to the ground as soon as they have passed the second cutting gap 62 '. Only when the capping in the Kappvortechniken 08, 08 'takes place exactly between two product sections, results in a gripper cylinder 22, the advantage that already both first product sections of strands gripped and properly can be processed.
