Pneumatically cushioned spinning ring system

摘要

The individual spinning rings of a ring-spinning or yarn-doubling machine frame, which are supported via a pneumatic cushion upon the respective ring holder and upon which a traveler is adapted to orbit, have compressed air introduced initially to support the rings. The compressed-air injection is interrupted when the rings reach a rotational speed enabling them to draw in the air for the cushion (self-sustaining airborne support cushion). Manually operated valves individual to each ring are in respective branch ducts and are provided for individual startup while a central control is provided for all of the rings.
