Control means for an open-end spinning machine

摘要

Open end friction spinning apparatus is provided in which there are one or more spinning units with respectively two adjacently arranged rollers, rotating in the same direction, and disposed to form a wedge-shaped slot therebetween for accepting fibers and spinning them into a thread of yarn by means of a friction effect. Devices are provided for monitoring the friction effect and adjusting the friction effect when necessary in order to maintain uniform spinning conditions at the individual spinning units and thereby control the quality of yarn produced.
