Abstract

See full text

A device for producing a twisted yarn in a combined spinning and twisting process has two open end spinning rotors positioned in a stationary protective pot, a hollow spindle axle into which the spun yarns produced by the spinning rotors are introduced, and a yarn guide channel extending radially from the spindle axle and driven in rotation about the spindle axis for guiding the yarn formed by the spun yarns. The yarn exits from the yarn guide channel and is guided external to the protective pot counter to the guiding direction within the spindle axle to a centering point positioned on an extension of the spindle axle. A device for supplying a dissolved fiber material to the two open end spinning rotors is provided. Two slide bearings for supporting the spinning rotor shafts, an electric motor with a drive member resting at the spinning rotor shafts, and for each spinning rotor two guide rollers are arranged within the protective pot. Each pair of guide rollers forms a wedge-shaped gap in which the respective spinning rotor shaft rests. For each spinning rotor shaft the rotational axes of the motor and of the correlated guide rollers determine an isosceles triangle, whereby the bisecting line intercepting the rotational axis of the motor is positioned within the center plane of the wedge-shaped gap.
