Abstract
An open end spinning unit is disclosed which includes a feeding device forming a fiber beard nipping line for a fiber beard extending downstream thereof. An opening device acts on a downstream end area of the fiber beard to open the fiber beard into separate fibers. A movable fiber take-up surface is provided separate from and downstream of the opening device for transporting the fibers to a yarn formation line. A fiber beard support guide guides the downstream end area of the fiber beard and the separated fibers so that the fibers continuously extend in a substantially stable direction without deflection as they travel between the nipping line and the take-up surface.
