  • a scrubbing load such as directional deflection.
  • One such problem is with weaving machines the Garnvorlage- and weft insertion area. If the accumulation of air in this area is not prevented, fiber fly, together with the weft thread, enters the shed and leads to tissue contamination. But it can also be significantly impeded or even prevented by the fiber fly, in the case of a pneumatic weft insertion, the weft insertion.

  • no blowing device is provided, the fiber fly is not stirred up so that it can not be deposited at another point of the weaving machine and there can lead to tissue contamination up to thread breakage.
  • the cleaning device is thereby arranged compact and efficient next to the weaving machine.
  • a particularly favorable embodiment of the cleaning device according to the invention provides that they form movable on the floor on rollers, so that it can be used as desired.
  • the thread passes. If necessary, the fiber fly is released by the directional deflection and, if these fiber constituents detach from the thread, they are certainly sucked out by the negative pressure.
  • An alternative embodiment of the cleaning device according to the invention provides to provide at least one suction device for fiber fly, having at least one suction connection box, which is at least partially disposed below and / or next to the weft thread in the direction of deflection.
  • the suction connection box is provided according to the invention with at least one suction opening for discharging sucked dust and fiber fly.
