ABSTRACT:
A device for damping vibrations of the holder of the cross-wound bobbin being driven frictionwise by the yarn guiding drum is provided with a spring (5) and a slidable pin (6) both placed within the hollow of the shaft (4) about which the holder (2) rotates. On the shaft (4) a stopper ring (7) is fixed immovably, abutting on the machine frame (8), and in the longer arm of the holder (2) a friction insert (9) is fitted. The spring (5) acting over the pin (6) on the lever (3) clamps the bobbin (1) in the holder arms (2), and shifts the holder to the left, pressing the holder arm with the friction insert (9) fitted therein down to the machine frame (8), and the friction force generated thereby damps the vibrations of the bobbin holder.
