ABSTRACT:
A multi-position rotary spinning machine includes an endless belt guided along the machine past a plurality of open-end spinning units each having a valve for operation by cam means of the belt to bring an eccentric port into and out of gas communication with another eccentric port of the valve by virtue of rotation of a rotary valve member driven by engagement of cam studs and carried by the belt with projections, respectively, of the rotary valve member.
The valves can be used for providing intermittent application of purging suction to the beater trash box of an open-end spinning or to a slub collection trough of a friction spinner.
