ABSTRACT:
Open-end friction spinning apparatus is disclosed which includes a plurality of commonly driven spinning units arranged adjacent one another and each including a friction roller pair defining a yarn forming wedge slot therebetween. To facilitate cleaning of the friction rollers, pneumatically operated cleaning nozzles are provided for each friction roller to be cleaned. Some arrangements have the cleaning nozzles fixedly disposed at each spinning unit, with actuating valves being controllable by a mobile servicing unit. In other arrangements the pneumatic cleaning nozzles are carried by a mobile servicing unit and are selectively moved to cleaning positions adjacent the friction rollers of respective spinning units to be cleaned.
