  • Such a spinning machine is known from EP 0 162 787 B1.
  • the drafting units of this spinning machine are each one disc-shaped suction rotor downstream, over which those of the The draft lines delivered and run on them Fiber lunches are compressed. This compression takes place through Suction of the fibers forming the fiber sliver against a narrow one Trace of perforation penetrating the jacket of the suction rotor, in particular one running around the circumference of the suction rotor Line of intake openings.
  • the fibers Due to the position of the suction rotors, at least one of the fibers is forced, not solidified by rotation to run a certain distance. Subject in this area the fiber fuse of the risk of damage. So she can or at least their fibers, for example, by the air flow of a traveling blower to be swirled. This would at least make hairiness of the yarn produced undesirably increased or even its Uniformity can be adversely affected. Furthermore, the Ring spinning device on the fiber sliver lying on the suction rotor Pull out, which affects an optimal compression of the fiber sliver.
  • the object of the invention was accordingly the distance, via a fiber sliver without guidance to such a suction rotor runs to reduce and keep the thread of a downstream twisting and winding device away from the compression zone.
