In the case of a supporting roller bearing for a horizontally arranged spinning rotor, it is provided that braking means are arranged below a tangential belt moving between two pairs of supporting roller. The braking means contain two brake shoes that can be applied essentially horizontally to the shaft from the direction of two sides, said brake shoes being arranged on tong arms. The applying of the brake shoes takes place in such a way that the brake shoe that during the application moves in moving direction of the tangential belt comes to rest against the shaft before the other brake shoe. In addition, it is provided that a tension roller loading the tangential belt in normal operation, during the braking, will not be moved off the tangential belt before both brake shoes are applied to the shaft.

Brake for an open-end spinning rotor

A bearing and driving assembly is disclosed for an open and spinning rotor unit of a spinning unit of the type having a rotor mounted on a rotor shaft, a twin disk bearing arrangement for rotatably supporting the rotor shaft and a tangential belt drivingly engaging the rotor shaft. A tension roller is loaded against the tangential belt. To minimize failures of such a system caused by a resonant system vibrations and to facilitate high spinning speeds with minimal manufacturing expenses, the supporting disk pairs are axially spaced a distance slightly larger than the axial width of the tension roller. Brake members are disposed below the tangential belt so as to be applied with substantially horizontal movement radially against the rotor shaft.
