Definitions

  • the invention relates to a device for guiding flat specimens in Folders, especially such folders, from a continuous web of material be separated.
  • Subordinate folders in web-processing rotary printing machines used stationary guidances used, which the cutting gap of a Cutting cylinder pair are subordinate.
  • Such stationary guided copy tours are usually designed so that the width of the width of the correspond to the maximum processable web format and the width of their guide gap are designed so that the distance between the lateral gap delimiting the guide gap Areas correspond to the thickness of a maximum processable material web strand.
  • the mentioned stationary guided tours are, for example, FR 2 751 630 or also US 5,839,365.
  • the invention lies based on the task of providing a copy guide for flat copies, which automatically depends on the material format to be processed and the thickness adapted to the material web and resettable from the outlet gusset of the pair of cutting cylinders is.
  • the advantages of the solution according to the invention can be seen above all in that the Outlet gusset of the pair of cutting cylinders passing through now on both sides of moving conveying surfaces are guided along a detection area, so that a fluttering or loosening of individual layers of a multi-layer flat specimen during the passage of the outlet gusset downstream of the cutting gap Cutting cylinder pair is effectively prevented.
