Friction ring for a friction roll for the driving of a spool on a textile machine

摘要

In order to drive a spool on a textile machine, a friction roll is provided, having a rotating body, carrying at least one friction ring. This friction ring is designed in the manner of a belt with two, open ends that are clasped together by two connectors. The two connectors, when linked together, form a releasable end fastening apparatus. The two connectors exhibit in this linkage, interlinking hooks. The fastening apparatus for the friction ring ends can serve simultaneously as a ring fastener to the friction roll. Further, the friction ring can be affixed, at a distance away from the two open ends, onto the friction roll with additional fasteners, which are uniformly distributed around the circumference of the friction roll. The two connectors and/or the friction ring exhibit a preselected radius of curvature which adapts to the radius of curvature of the outer circumference of the friction roll.
