Abstract: An apparatus for damping vibrations in high-voltage devices has a support arrangement for the high-voltage device. The support arrangement includes support elements interconnected by connection elements. Intermediate elements, in particular coated washers, are arranged between the connection elements and the support elements and/or between different support elements. There is also described a method for damping vibrations, in which connection elements spatially fix support elements of the support arrangement of a high-voltage device in a mechanically stable manner. When mechanical vibrations occur on the high-voltage device, the connection elements dampen the mechanical vibration in a defined manner via a predetermined sliding friction with the support elements and via a spatially predetermined play in relation to the support elements.

Abstract: An opening roller housing (1) for an opening roller (2) of an open-end spinning machine (3) has a feed opening (4) for feeding a fiber material (5) into the opening roller housing (1), a delivery opening (6) for drawing opened individual fibers (7) out of the opening roller housing (1), a trash removal opening (8) for extracting trash (9) out of the fiber material (5), and an inner circumferential wall (10), which surrounds the opening roller (2) during operation and has a fiber-guiding area (11), which extends from the feed opening (4), over the trash removal opening (8), and up to the delivery opening (6). The opening roller housing (1) includes a hollow cylindrical ring (12).

Abstract: A thread draw-off nozzle for an open-end spinning device includes a nozzle insert configured to deflect a yarn produced by the open-end spinning device. A nozzle frame fixes the thread draw-off nozzle in the open-end spinning device. The nozzle frame includes a cylindrical shank, which has a centering diameter and a length that is shorter than half the centering diameter.

The shank (6) of the nozzle frame (4) is provided with a centering diameter (ZD) and the cylindrical shank (6) of the nozzle frame (4) is shorter than half the centering diameter (ZD).

Abstract: A support for a combing means for an opening roller comprises an opening roller combing means, which is designed as a saw-toothed helix having multiple thread grooves. The number of threads amounts to approximately between one twentieth and one thirthieth (expressed in millimeters) of the outer diameter of the opening means. In addition, the angle of inclination (expressed in degrees) of the helix amounts to between 0.5 and 0.7 times the number of threads. The angle of inclination of the helix should not exceed 2.5°.
