Abstract: A spinning device comprising a spinning box housing; a spinning rotor having a spinning cup on a rotor shaft; a cover element; a traveling belt acting tangentially on the rotor shaft; a rotor brake; a pivotable expander roller moveable within a maximum pivot angle via a pressure lever system connected to the brake gear of the rotor brake between an operative position when the spinning box is closed in an inoperative position wherein the expander roller is automatically lifted off the tangential belt and the rotor brake is applied to the rotor shaft when the spinning box is opened; a brake and locking lever having a locking recess in contact with an arresting roller arranged on the cover element; and an arrangement in the pressure lever system for absorbing shock-like forces acting on the expander roller and for preventing the forces from being transmitted to the brake and locking lever.

Abstract: A conduit plate adapter for use with an open-end spinning device, comprising a base body having a central passage bore extending therethrough and a yarn withdrawal nozzle mouth fixedly secured directly in the central passage bore. The conduit plate adapter of the present invention is removably inserted into a conduit plate.

Abstract: A filter device (4) for a cheese-producing textile machine (1) having a plurality of pneumatic devices, e.g., open-end spinning devices (2), service units (3), etc. The filter device (4) has negative pressure filter chambers (6, 6′), each divided via a closure mechanism (9, 9′) into a main filter chamber (7, 7′) and a reserve filter chamber (8, 8′), and an intermediate chamber (14), to which a negative pressure source (5) is connected. Closable suction openings (12, 12′) and (13, 13′) in the main and reserve filter chambers, respectively, are connected with the intermediate chamber. The suction openings (12, 12′) and (13, 13′) are equipped with respective closure elements (15, 16) and (15′, 16′) which are functionally coupled such that, upon closure of one suction opening (12 or 12′), the other suction opening (13 or 13′) is automatically opened.

Abstract: A filter chamber (8) for the vacuum system of a textile machine (1) comprises connection conduits (14, 15) between a vacuum source (7) and a suction conduit (9) running the length of the machine. A filter 10 is arranged inside the filter chamber (8) at an interval from the wall (13) of the filter chamber to divide the filter chamber (8) into a dirty-air area (18) and a clean-air area (17). The filter element (10) comprises at least two filter elements, a relief element (11) and a collector element (12). The relief element (11) is disposed in the filter chamber (8) at a spacing from the wall (13) of the filter chamber such that a primary component of the flow (16) of suction air from the conduit (14) to the conduit (15) for the vacuum source (7) moves parallel to or at an acute angle (I) to the relief element (11).
