ABSTRACT:
To ensure for the effective removal by suction of thread breaks, even at long ring spinning machines in an economical manner, a second duct or channel is provided above a package creel and parallel to a first suction duct or channel. Both ducts discharge into a common suction chamber. Connecting channels conduct a portion of the air quantity sucked-up by suction nozzles into the second duct or channel. The cross-section of the second duct is enlarged, with increasing length of such duct, in a manner such that there prevails in both ducts essentially the same mean air velocity.
