ABSTRACT:
In the case of a device for open-end rotor spinning with a spinning rotor, the spinning rotor is provided with a fiber collecting groove and a fiber sliding surface. The fiber sliding surface is provided with structured areas which are set in the opposite sense of rotation to the spinning rotor, viewed in the direction towards the fiber collecting groove. The mouth of a fiber feed duct is disposed facing the structured areas with a component in the sense of rotation of the spinning rotor. Due to the way they are arranged, the structured areas, which cross the path of the fibers, exert a propelling force on the fibers in the direction of the fiber collecting groove. The sliding of the fibers into the fiber collecting groove does not take place exclusively by means of the centrifugal forces anymore, so that in design the traditional angle of taper of the fiber sliding surface is not necessary.
