ABSTRACT:
Two juxtaposed drums are arranged to rotate in the same sense and are closely spaced apart to define between them a throat and two gaps tapering towards the throat on opposite sides thereof. The drums are operable to engage flying fibers entering one of the gaps and to twist the fibers together so as to form a twisted yarn. Draw-off rolls are provided for withdrawing the twisted yarn from the throat in the longitudinal directon thereof. A suction duct extends into the other gap and has an inlet slot which extends along the throat.
