A hybrid yarn for producing molded parts having a thermoplastic matrix and reinforcing fibers embedded therein. The hybrid yarn includes a core substantially made of staple fibers aligned in a straight line in the longitudinal direction of the hybrid yarn, and a cover made substantially of staple fibers wound helically about the core. The staple fibers forming the core and the staple fibers forming the cover each are made of an intimate mixture of thermoplastic matrix fibers and reinforcing fibers.

Hybrid yarn for producing molded parts

An apparatus and associated method for spinning staple fibers on a ring spindle machine includes a ring spindle disposed downstream of a drawing frame outlet. A thread guiding device is disposed between the drawing frame outlet and the ring spindle and includes a twisting apparatus that is magnetically coupled with the ring spindle so as to rotate at the same speed as the ring spindle. The twisting apparatus has a thread braking device configured along a path of the thread through the twisting apparatus. An attachment configured at a top of the ring spindle has a plurality of circumferential grooves configured to catch the thread coming from the twisting apparatus and being wound onto the ring spindle.
