Definitions

  • the invention relates to a web catching device with two Catching elements according to the preamble of claim 1.
  • DE-PS 21 56 505 shows a device for Prevention of printing unit damage in the event of paper web tears, where a pair of pinch rollers for grasping the paper web is provided. These pinch rollers are in print mode parked from each other and formed by one A paper web is guided without contact.
  • the invention has for its object a Web catching device with two catching elements create, the switching time are further reduced can.
  • the web catching device according to the invention is in the Drawing shown and will be described in more detail below described.
  • the drawing shows a schematic side view of the web catching device according to the invention.
  • a so-called web catching device is arranged between, for example, a printing unit and a downstream dryer of a web-fed rotary printing press.
  • at least one roller 1 can be brought into operative connection with the second roller 2.
  • the second roller 2 For this purpose, e.g.
  • rollers 1, 2 each mounted on a pivot lever 6 and pivoted by means of pneumatic cylinder 7. Both rollers 1, 2 can be driven at web speed via drives, not shown.
  • z. B. a4 3 mm
  • the sheets 8, 9 are preferably approximately 10 mm wider than the width of the web 4. An intermediate space 11 through which the web 4 runs approximately in the center is thus delimited by the sheets 8, 9.
  • the sheets 8, 9 are provided on their outer sides with two bent legs 14, 16 pointing away from one another and pointing in the transport direction “T”. It is also possible to direct these legs 14, 16 against the transport direction "T” in such a way that the distance a1 becomes a distance a3, e.g. B.
  • the sheets 8, 9 can also be provided with side sheets, so that there is a guide channel which is closed on four sides and is only open on the entry and exit side of the web 4.
  • a second pair of plates 8, 9 can be provided in mirror image of the pair of clamping rollers before the pair of clamping rollers. It is also possible to attach only a pair of sheets 8, 9 in front of the pair of pinch rollers.
  • the width s of this gap 3 should be minimal to the shortest possible turn-on time in lightweight construction executed rollers 1, 2 in the event of a web break to reach.
  • the web 4 is approximately in the middle of the Catch gap 3 and the sheets 8, 9 performed, the Width s of the catch gap 3 is preferably less than the distance a1 of the aligned on the capture gap 3 Sheets 8, 9. Between lane 4 and upper or lower Sheet 8, 9 independently forms an air cushion that the web 4 stabilized. Flutter and swing of the web 4 is thus largely avoided. Therefore, the Width s of the catch gap 3 between the rollers 1, 2 be minimal.
  • the sheets 9, 11 are flat in the present example executed, but they can also be aerodynamically favorable Profile shapes, e.g. B. have a wing shape.
