Brake for an open-end spinning rotor

摘要

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.
