Abstract
The present invention relates to a brake disk arrangement for a yarn tensioning device wherein at least one of a pair of opposed facing brake disks can be acted upon by a variable pressing force in the direction of the other brake disk. According to the present invention, rotary motion is transmitted from one brake disk to the other in a simple manner, without affecting the brake force, by connecting to one of the brake disks a concentric magnet that is secured against relative rotation with respect to this brake disk, and by connecting to the other brake disk a concentrically arranged body of hysteresis material which is secured against relative rotation with that brake disk. At least the brake disk that can be acted upon the variable pressing force comprises a nonmagnetic material and is changeable in position axially relative to the magnet or the hysteresis material associated with the disk. In alternate embodiments, both brake disks may be provided with a magnet.
