double-strand twisting spindle with a yarn tension device

摘要

The thread brake (14) comprises a brake element (29), which is stored in the area of a hollow axle (5) of a spindle between an upper brake surface (28) and a lower brake surface (30). The thread brake is pneumatically detachable for inserting a thread (3,4). An upper piston (27) receives the upper brake surface, and is guided with a play (S) inside a housing of the thread brake.
