Abstract
Below a ring-spinning spindle, a clamping ring and a clamping sleeve have frustoconical surfaces, at least of one first textured to increase the grip on an underwinding thread. The clamping sleeve, for example, may be spring-biased to axially engage the clamp and force may be required to open the clamp.
