Abstract
The thread end to be used for rejoining in an open-end spinning frame is prepared by cutting it to size and then introducing it into a pipe with a vigorous air flow running through the pipe and contacting the thread end with a vibrating blade, freeing the end of short fibers, tapering the thread end and untwisting the fibers that comprise the thread end.
