ABSTRACT:
A friction spinning frame including a pair of twisting rollers disposed substantially in parallel and driven in the same direction to each other at a small gap therebetween to form a yarn forming zone of a valley shaped profile on upper surfaces of the twisting rollers along the gap. At least one of the twisting rollers is a perforated hollow roller including an outer shell having a plurality of perforations on the entire outer surface thereof and a suction device for providing a suction force through the perforations, whereby staple fibers are twisted to form a yarn while being sucked and held on the yarn forming zone. A supporting system of the perforated twisting roller is such that a suction pipe, a part of which is accommodated in the outer shell and has a suction mouth extending close to an inside wall of the outer shell in the axial direction of the perforated roller, is fixedly secured to a machine frame; a beariung is fixedly accommodated in the suction pipe; and a shaft is rotatably supported by the bearing at one end portion thereof and is fixedly secured to the oute shell at the other end portion thereof.
