More Information
Summary:A device for separating fibrous material, for use with textile machines, and particularly open end spinning machines, includes a housing which defines a chamber. During operation of the device, and for the purpose of doffing separated fibers, an underpressure is maintained in said chamber. A carding roller is located within the chamber and is mounted for rotation by a bearing arrangement, which is itself at least partially located in the chamber. The bearing arrangement has at least one portion from which lubricant may leak and then, under the influence of the prevailing underpressure, be sucked into contact with the fibrous material being separated. To prevent such possibility, a pressure-compensation arrangement is provided which is adapted to prevent the lubricant from coming under the influence of the underpressure.
