ABSTRACT:
A device is disclosed for damping the vibrations of a package on spinning, twisting or winding machines. Damping elements act on the swivel-mounted package holders, which damping elements are arranged on the machine frame and which are effective on the swivel direction of the package holders. The package holders are supported with tube sections on a swivel axle which is secured to the machine, and support the packages, which are pressed onto a driving roller and are rotatably supported thereon. In the swivel direction in which the packages are lifted from the drive roller, the damping is greater than in the swivel direction in which the packages are pressed onto the drive roller. The cylindrical outer contour of each individual tube section is surrounded, at a predetermined angle of contact, by a close fitting brake belt which is actuated by friction. One end of the brake belt is secured in a non-movable way on a stationary mounting, while the other end is secured to a loading spring. This loading spring tightens the brake belt in the swivel direction in which the package is lifted from the drive roller. As the rigidly supported end of the brake belt does not give, the damping effect comes into force immediately in the swivel direction which leads away from the drive roller. The counter-movement is, in contrast, hardly braked at all, as this slackens the brake belt.
