Abstract (en)
[origin: WO8701742A1] In order to resume spinning on an open-end friction spinning device (10) with two frictional spinning elements (100, 101) driven in the same direction and forming a tapered gap (102), of which at least one can be provided with suction, the fibers are fed continuously to the tapered gap (102) and are immediatly withdrawn again from the latter. During continuous fiber feed the withdrawal of the fibers from the tapered gap (102) is interrupted, so that the fibers remain in the tapered gap (102) and for a rotating collection of fibers. A thread end is than placed on this collection of fibers. Next, the newly-formed thread is withdrawn from the tapered gap (102) during the continuing binding together of the fibers continuously fed to the tapered gap (102). For withdrawal, a controllable suction air nozzle (111) oriented against the tapered gap (102) is linked with the fiber feed duct (24). The friction spinning elements (100, 101) can be moved radially in relation to one another.
