ABSTRACT:
The invention is directed to an apparatus for blowing off a thread end from a full cheese formed by an open-end spinning and winding machine. The apparatus includes a pipe conduit which is provided midway along a transport path through which the full cheese passes. The pipe conduit is provided with a plurality of nozzles which inject high speed air from the inner surface of the pipe conduit toward the outer surface of the full cheese which is passing through the pipe conduit. The injected air causes the thread end to be raised from the full cheese surface and to flutter in back of the full cheese.
