Abstract
A multi-twisting spindle has a hollow spindle axle defining the axial direction of the twisting spindle. A bobbin support including a support bottom and a protective pot is rotatably connected to the hollow spindle axle. A rotor disk is fixedly connected to the hollow spindle axle. A balloon limiter is connected to and rotates with the rotor disk. The protective pot is positioned radially inwardly in the balloon limiter. A gap is formed between the balloon limiter and the protective pot. The protective pot is driven in a rotational direction opposite to the rotational direction of the balloon limiter. The rotor disk has a yarn guide channel connected to the hollow spindle axle and extending radially outwardly away from the hollow spindle axle. A deflection channel is connected to the yarn guide channel and has an outlet that opens into the gap. A yarn catch ring is arranged axially spaced below the support bottom in a radially outer area of the support bottom. The yarn catch ring rotates together with the balloon limiter. The yarn catch ring has an outer diameter that is smaller than the outer diameter of the protective pot.
