Definitions

  • the present invention relates to a device for guiding a material web a cutting device in which the material web is cut or perforated, especially in a web-fed rotary printing press, according to the preamble of Claim 1.
  • Cutting devices in which materials, for example a paper web, are cut or perforated are known.
  • such devices include rotating cutting knife or several cutting knives.
  • the known Cutting devices is a stationary or directly opposite the cutting knives rotating groove arranged, for example, as a strip of rubber or a other flexible material is formed and is contacted by the cutting knife after this has cut the web.
  • the path is between the rotating knife and of the stationary or rotating groove, and the cutting knife moves towards and away from the paper and the groove. Every time that Cutting knife is moved towards the paper and the groove, the paper is cut or perforated. If the cutting knife moves away from the paper and the groove, it will Moving paper so that a new section can be cut. After this
  • the paper is usually cut or perforated to a belt system hand over which the cut signatures or the perforated sheet one Feeds further processing device.
  • a disadvantage of these conventional cutting devices and methods is that that the cut edge of the cut signature or the perforation of the perforated Path a gap between the cutter and one of these downstream belt system for the further transport of the signatures or the perforated Train must pass. The path is not guided when passing this gap. Therefore there is a risk that the corners of the signatures or the perforated sheet of deviate from the envisaged path to the belt system and be bent if the Signatures or the perforated web run into the belt system. This twisting of the Corners of the signatures or the perforated sheet is undesirable because of the signatures or the perforated web section in question can become unusable in this way.
  • the present invention prevents the corners of a signature or perforated web section cut from bending when the signature or web section passes the space between a cutting device and a downstream transport system.
  • a guide element is provided which guides the signatures or the web section between the cutting device and the transport system.
  • the guide element guides at least the corners of the signatures or web sections in such a way that the corners are prevented from bending over while the corners between the Pass the cutting device and the downstream transport system.
  • the cut signatures or a perforated sheet can be used at least one edge of the web adjacent, rotating guide element intended.
  • the rotating guide element preferably rotates into one Direction of rotation of the cutting device perpendicular to the direction of movement of the web parallel direction and preferably includes guide fingers on each side of the signatures or track sections.
  • the rotating Guide element can be formed as a single unit.
  • Another embodiment The invention, which is particularly suitable for perforated web sections, provides that the guide element consists of two units arranged on both sides of the track.
  • the rotating guide element guides both sides of the corners of the signatures or perforated web sections after the cutting process and preferably rotates with it the speed, which is essentially the linear speed of the web corresponds.
  • the rotating guide element carries the signature or the perforated one Track section preferably, while this the space between the Cutting device and a downstream belt system pass, and removes from the signature or the perforated web section as soon as the front edge of the Tape system has been captured. This way the corners of the leading edge of the cut signatures or perforated web sections, while the Gap happen, so that the corners of the signatures or perforated web sections is prevented.

  • the blade 6 of the knife 14 moves towards the groove cylinder 12 and cuts or perforates the web W passed between the knife cylinder 13 and the groove cylinder 12 at regular intervals. These distances are dependent on the retraction speed of the web W and the speed of rotation of the knife cylinder 13 and the grooved cylinder 12.
  • the rotating or generally rotating guide element 1 shown in FIGS. 1-4 rotates in the direction indicated by the arrow RG around a single shaft 30 which forms an axis 20.
