method and device for interrupting the vorgarn intake to the streckwerken a spinnmaschine

摘要

Normal feeding of supply strands into drafting systems of a textile yarn forming machine, for delivery as attenuated strands, is interrupted in response to breakage of the corresponding attenuated strands. Interruption of supply strand feeding is actuated by redirection of flowing air from a traveling pneumatic cleaner to impinge upon strand interrupting members and selectively displace those members from first positions to second positions in which corresponding supply strands are engaged and restrained against movement into corresponding drafting systems.
