Abstract
A friction disc for rotating a twisting tube of a false twisting device for crimping thread is provided with a peripheral surface which slings any oil on the surface therefrom. The peripheral surface of the disc has an annular groove therein which is substantially frusto-conically shaped in cross-section and intersects the surface at an angle to provide an edge from which the oil will be slung by centrifugal force as the disc rotates.
