ABSTRACT:
A device for bobbin doffing on a spinning frame. The device comprises a conduit connected to a suction source and means for replacing the bobbin with a yarn winding tube. This suction conduit is carried to move its suction inlet between a first position adjacent the yarn length stretched between a spinning unit and the bobbin, and a second position at which a pusher brings the yarn in contact with the surface of said winding tube.
The invention is particularly suitable for use on open end spinning frames.
