Definitions

  • so-called aerodynamic web formers are used for the production of nonwovens.
  • the dissolved fibers are dropped or sucked off a garnished roll.
  • a so-called "knife” is used, which is set at a distance of 0.5 - 1.5 mm from the tips of the clothing of the roller.
  • This knife obstructs the air jacket surrounding the roller and thus promotes a lifting of the fibers from the clothing.
  • Exemplary is the DE 2535544 (Dupont ) Fig. 1 Position 12 called.
  • a special embodiment shows the DE 10255518 (Erko ).
  • the knife shows an extra edge at the top to increase the air jam.
  • the blades are made of flat steel with a maximum thickness of 30 mm, milled or ground.
  • the fibers are then sucked onto a sieve belt or drum to form a web. These webs are always isotropic because the fibers impinge approximately perpendicular to the screen.
  • the object of the invention is to provide an aerodynamically formed nonwoven in which the fibers have an orientation. This is achieved in that the knife is extended by a slide, so that the fibers do not impinge preferably vertically, but at an angle rather flat on the screen surface.
  • the slide can be massively made with the knife in one piece; Advantageously, it is made of an additional stainless steel sheet.
  • the chute may consist of a plane or have multiple bends or be rounded. In the case of a sieve drum, the reference plane is the tangent to the sieve drum in the center of the discharge cone. There, the largest pulp mass is dropped.
  • Fig. 1 shows a discharge roller of a web forming 1), on which the fibers are excavated by a knife by means of a Aushebestelle 2) and via a slide 3) to a suction point 7) of a moving screen belt 4) arrive.
  • a suction box 5 an intake stream is formed.
  • the Aushebemesser is attached to a trough 6).
  • the angle extends from the suction surface with over 135 ° to the slide surface.
  • Fig. 2 shows the same arrangement with a rounded slide. In the lower part of the slide, the angle of the slide is more than 135 ° to the suction surface.
  • the slide can z. B. via a pivot axis 8) are pivoted.
  • the suction is advantageously moved when pivoting in an ideal position with high intake.
  • the angle may also be the tangent of a screen drum at the point of preferential impact of the fibers.
