ABSTRACT:
An open-end friction spinning machine is disclosed which has a large number of spinning units arranged next to one another, each containing two friction rollers arranged next to one another to form a wedge-shaped yarn forming gap. By means of a joint drive the friction rollers are driven in the same rotational direction. A servicing apparatus is provided which in each case can be applied to a spinning unit, said servicing apparatus having an auxiliary drive for the friction rollers, said auxiliary drive containing an auxiliary drive element that can be applied simultaneously to the shell surfaces of both rollers.
