Definitions

  • the invention relates to a press section of a machine for manufacturing and / or Refining a fibrous web, in particular a paper, cardboard or tissue web, consisting of at least two press nips, each formed by a pair of rolls, whereby in addition to the fibrous web at least one endlessly running press felt Recording the squeezed water passed through the press nips and at least the each lower press roll of the pairs of rolls cylindrical and at least one upper Press roll as a shoe press roll with a concave pressing surface to form a elongated press nip is formed.
  • the pre-wrap of the lower press roll is therefore usually through the course of the Fibrous web and the press felts correspondingly changing guide roller enlarged.
  • this guide roll is often designed as a suction guide roll, this means a considerable effort.
  • the object of the invention is therefore, in such press sections Wrapping the lower, cylindrical press roll with as little as possible Increase effort.
  • the object was achieved in that in the web running direction first pair of rollers arranged higher than the following pair of rollers, each by the Axes of the press rolls of the roll pairs running press line opposite the Vertical is inclined in the web running direction and the fibrous web the press nips leaves horizontally or preferably inclined downwards.
  • lower press roll can now Fibrous web in a direct way, i.e. without an additional guide roller from one Take-off roller are guided to the first press nip. That of a press felt looped take-off roller supports the in the form of a suction guide Takeover of the fibrous web from the forming wire of the upstream former Machine.
  • the pre-wrap of the two lower press rolls is determined by the inclination of the Press line enlarged in the direction of web travel in a simple manner.
  • the optimum angle of inclination of the press line with respect to the vertical was Range from 10 to 20 ° determined.
  • the fibrous web Because of the high water volume, at least through the first press nip on both sides the fibrous web each run at least one press felt through the press nip.
  • the press section consists of two, each formed by a pair of rollers Press nips 2, each press roll 4,5 having its own endlessly running press felt 3 for receiving and transporting the water squeezed out in the press nip 2 has.
  • Each pair of rollers consists of a lower cylindrical press roller 4 and a press roll 5 arranged above it in the form of a shoe press roll.
  • This Shoe press rollers have a flexible press jacket that is attached to a pressure shoe 17 runs with a concave pressing surface. This enables the formation of elongated ones Press gaps, which improves the drainage result.
  • the press felts 3 are inside the press section via guide rolls 15 and Suction guide rollers 11 guided, the fibrous web 1 constantly with at least one Press felt 3 is in contact. This improves the web guidance, especially at high ones Speeds.
  • the removal of the fibrous web 1 from the forming wire 16 of the upstream former will supported by a suction guide roll 11 wrapped by the upper press felt 3.
  • the Delivery of the fibrous web 1 to a dryer fabric 14 of the following dryer section happens here from the lower press felt 3 of the second pair of rollers.
  • the collecting device 12 serves for receiving and the removal of the water thrown from the upper press roll 5 and can also be vacuumed. Because the jackets of the shoe press rollers are grooved and are blind drilled, they also take up a lot of water in the press nip 2. As a result also thrown a lot of water. Of course, the bottom ones are grooved Press rolls 4 are provided in a known manner with collecting devices.
  • the lower press roll 4 of the second press nip 2 is in FIG provided with a smooth jacket surface and not wrapped in any press felt 3.
  • the delivery of the fibrous web 1 from this lower press roll 4 takes place Dryer screen 14 of a following dryer section, which is one of the dryer fabrics 14 looped suction guide roller 11 is supported.
