Definitions

  • the invention concerns a method and an equipment in cutting/guiding of a lead-in strip in a paper/board machine.
  • a what is called lead-in strip is formed out of the web. This takes place in a certain position in the machine by first cutting a side band into the web and by passing the side band and the web initially as a single unit into the pulper.
  • the lead-in strip is formed out of the side band in a certain position so that the side band is cut off and that the cut-off end is passed further in the machine, for example, into a rope feed and further in the machine.
  • the lead-in strip thus formed can be guided into the rope feed, for example, by means of blowing, and along with the rope feed further in the machine. After completed threading of the lead-in strip, the lead-in strip can be widened to full width of the whole web.
  • the equipment in accordance with the invention for the formation of the lead-in strip a unit of equipment be used which can be brought into its position into connection with the edge band that has been cut.
  • the equipment also cuts off the end of the edge band by means of a cutting device, preferably a water cutter, connected with the equipment.
  • the end of the lead-in strip thus formed can be guided further by means of the separation blowing connected with the equipment and by means of the subsequent support blowing further, for example, into the rope feed.
  • the edge band can be cut off, and the cut edge band can be separated from the cutting face and transferred further.
  • the cutting takes place preferably against a roll face, but the cutting may also take place, for example, against a felt after a press nip.
  • the lead-in strip is cut off against a felt and transferred in accordance with the invention, by means of support blowings, directly into the dryer section into connection with the drying wire in the dryer section.
  • Figure IB shows the equipment viewed in the direction of the arrow K j in Fig. 1A.
  • Figure 2B shows a stage in which the equipment has been brought into the operating position and in which stage, at the same time, the cutting is carried out by means of the equipment.
  • the device 10 in accordance with the invention is brought into connection with the web W.
  • the cutting of the edge band Wa that forms the lead-in strip W' into the web has taken place in a position B j preceding the position B 2 .
  • the edge band Wa is cut off by means of a cutting device 15, favourably a device that produces a pressurized water jet D j .
  • the equipment 13a l 5 13a 2 , 14,15 is placed in a position pulled to the side.
