Process for the stopping and restarting of an arrangement for open-end friction spinning and a device for this purpose

摘要

A process is provided for operating open-end friction spinning machines of the type including movable friction surface parts defining a yarn forming region and a suction device for creating a suction effect on the yarn forming region. The process includes reducing the suction effect when spinning operations are interrupted, and interrupting the suction device at a point no later than the return of a yarn end into the yarn forming region. An apparatus for performing the process is also provided.
