This invention relates to a device for removing short fibers from a mass of ibers. A pair of perforated cylindrical bodies are opposed to each other with a predetermined spacing defined therebetween, and static electricity is applied across the perforated cylindrical bodies. A suction-wise removing device is installed in at least one of the perforated cylindrical bodies. The initial end of a transfer conveyor is located on the surface of one perforated cylindrical body adjacent the opposed region. Short fibers contained in the mass of fibers fed to the opposed region by a feeding device are drawn into the suction-wise removing devices through the through holes in the cylindrical bodies by the action of electrostatic force and suction air currents. The mass of fibers having the short fibers removed therefrom are oriented by electrostatic force and transferred by the conveyor while being maintained in this oriented state.

Device for removing short fibers

In the present invention, a plurality of fixed flats are disposed in juxtaposition to one another, and an opening 5 to 33 mm wide is formed between each pair of adjoining fixed flats, in such a manner that the dust is entrained in the discharge air current produced at the upstream side of the opening and extracted out of the opened fiber mass.
