Definitions

  • the invention relates to pull-in tips and a separating device according to the preamble of claim 1, 13, 17 or 19.
  • Such drawing-in tips are required, for example, in web-fed rotary printing presses, in order to start a printing material web, for example a paper web, with a device for drawing the printing material web into the web
  • Web-fed rotary printing press for example a chain conveyor system.
  • a coupling device is provided on each of the pull-in tips, so that the pull-in tip can be coupled to the device for pulling in the print material web after attachment to the end of the print substrate web to be drawn in.
  • the conveying movement of, for example, the chain conveyor system can then be transferred to the paper web via the drawing-in tip, the tensile forces being introduced over a large area into the printing material web by the drawing-in tip.
  • drawing tip In order to be able to guarantee a reliable drawing in of the printing material web, the drawing tip must be securely connected to the printing material web. Another goal in the construction of drawing-in tips is to be able to detach the drawing-in tip from the printing material web as completely as possible after the printing material web has been completely drawn into the printing press.
  • EP 00 94 631 B1 discloses a draw-in tip made of plastic film which can be fastened to a paper web by means of a double-sided adhesive tape.
  • a pull-in tip which has two flexible cover pieces lying one above the other at its rear end. These cover pieces contain magnetic foils, so that the magnetic pull attracts the beginning of the Substrate can be frictionally clamped between the cover pieces.
  • a drawing-in tip is known in which the beginning of the printing material web to be drawn in is also clamped frictionally between two magnetized foils due to magnetic forces.
  • shaped elements are provided in the foils, by means of which the printing material web is deformed when clamped.
  • the invention has for its object to provide retractable tips and a separator.
  • connection between the drawing-in tip and the material web can be reliably established in a simple manner.
  • recesses are provided in the pull-in tip in such a way that when the pull-in tip lies in the correct position on the beginning of the material web to be drawn in, one side of the material web is visible through the recesses.
  • an adhesive tape is then applied on the other side of the pull-in tip such that the adhesive layer of the adhesive tape comes into contact with the material web through the recesses.
  • the adhesive tape should be removed from the pull-in tip in most applications.
  • the pull-in tip is at least partially equipped with a non-stick coating. This non-stick coating should, as far as possible, allow the adhesive tape to be removed from the pull-in tip essentially without leaving any residue.
  • magnetically acting connecting elements for example two interacting magnets or a magnet interacting with a metal piece
  • the coupling device can also be designed in the manner of a Velcro strip, which can be coupled to the device for pulling in the material web.
  • the pull-in tip is made of flexible materials, for example plastic film, it can only be handled reliably when both ends of the pull-in tip are under tension due to its lack of dimensional stability when rolled out.
  • at least one fixing element is arranged on the pull-in tip in such a way that the pull-in tip rolls up in a conical shape and can be fixed.
  • This fixing element can be designed, for example, in the manner of Velcro strips, which are arranged on the top and bottom of the pull-in tip.
  • the pull-in tip is then rolled up in the desired cone shape, this shape is fixed due to the contact of the Velcro strips in such a way that the pull-in tip can no longer open independently.
  • the coupling element on the pull-in tip projects in a defined position from the center of the conically rolled-in pull-in tip. If the pull-in tip is then to be used again, the coupling element can be coupled to the device for pulling in the material web and placed under tension in such a way that the Velcro strip loosens and thereby the cone-shaped rolled-up pull-in tip is unrolled and pulled apart flat.
  • a separation device is therefore proposed, by means of which the separation of the drawing-in tip from the material web can be carried out in a simple manner.
  • the separating station is designed such that the material web can be severed along the contour of the recesses in the pull-in tip. That is, the material web is cut along the contour of the recesses, so that the part of the material web adhering to the adhesive tape is detached from the remaining material web.
  • the material web can thus be separated from the pull-in tip, with the beginning of the material web having recesses whose size and shape substantially correspond to the recesses in the pull-in tip.
  • the adhesive tape is also cut even when the material web is cut in the separation station, it is irrelevant for detaching the material web from the pull-in tip.
  • the adhesive tape is retained in one piece when the material web is severed. As a result, it is possible for the stamped-out parts of the material web to be removed at the same time by simply removing the one-piece adhesive tape from the pull-in tip.
  • the cutting of the material web along the contour of the recesses can of course be achieved by using mechanical tools, for example suitable punching dies. It is particularly advantageous if at least one pressure element is provided in the separation station, by means of which the material web in the region of the recesses of the drawing-in tip can be subjected to overpressure and / or underpressure. The resulting pressure difference on the material web can then be used to cut the material web in the region of the recesses. This saves moving parts and their drive in the separation station. In addition, the unwanted severing of the adhesive tape can be avoided by such a pressure separation process due to its mechanical stability, which is significantly higher than that of the material web.
  • a suction device is provided at the separation station, with which the adhesive tape with the detached part of the material web adhering to it can be sucked off from the pull-in tip. This is achieved, for example, by applying a negative pressure to the pull-in tip in the area of the adhesive tape, so that the adhesive tape is detached by the pressure difference in the area of the recesses in the pull-in tip.
