摘要： An open-end spinning device comprises a spinning rotor (21) rotating in a rotor housing with a spinning insert (24) supported rotatably with respect to the spinning rotor (21) coaxially to the rotor axis (33). The spinning insert (24) can be caused to rotate as a function of the rotary motion of the spinning rotor (21) via a contactless entrainment of the spinning insert (24) by means of permanent magnets (32) attached to the spinning insert (24). In this manner a simple and reliable entrainment and an automatic adjusting of the rotational speed of the spinning insert (24) in the spinning rotor (21) are achieved.

摘要： A spinning rotor (1) with a spinning cup (2) has an interior surface coated with a nickel dispersion layer (6) of an essentially even layer thickness having a concentration of hard material grains (7) embedded therein which is clearly less at the surface of the fiber slide face (9) than in the rotor groove. The coating is produced by bathing the spinning cup in a nickel dispersion bath during the final stage of which the concentration of the hard material grains in the bath is reduced at least in the bathing area, while the spinning cup is moved in this bath and rotated around its longitudinal axis while maintaining the spinning cup in a spatial orientation relative to the bath wherein an imaginary plane passing through the rotor groove is at least approximately perpendicular to the surface of the nickel dispersion bath.

摘要： The fiber sliding surface and the fiber collecting groove of an open-end spinning rotor are provided with hard particles embedded therein. After a certain length of operation time of the spinning rotor, the particles in the fiber collecting groove have a larger particle size than the particles in the fiber sliding surface. Thus it is ensured that the fiber collecting groove has a better "grip effect" relative to the fibers to be spun than the smoother fiber sliding surface.

摘要： An open-end spinning device comprises a spinning rotor rotating in a vacuum-loaded rotor housing which can be closed by a conduit plate having a receptacle receiving a replaceable conduit-plate adapter and a locking device, e.g., a bar spring, for spring-biasing the conduit-plate adapter into the receptacle. A blocking device comprising a hood-like cover is associated with the locking device for movement into an operating position only when the locking device is positioned in a locking position in which it reliably fixes the conduit-plate adapter.

摘要： A rotor type open-end spinning machine of a structure in which fibers moving slidingly on an inner wall surface of an outer rotor (2) are prevented from falling at a location where a fiber bundle is being stripped off from a fiber collecting/bundling section (7) while being twisted concurrently. An inner rotor (5) is disposed within the outer rotor (2) and positively driven independently of the latter. A delivery passage (20) is formed in the inner rotor (5) for guiding a fiber bundle (F) bundled in a fiber collecting/bundling groove (7) to a yarn withdrawing passage (14). An annular negative-pressure chamber (6) is formed radially outward of the fiber collecting/bundling groove (7) of the outer rotor (2) with air discharge holes (9) being provided for communicating the negative-pressure chamber (6) to the exterior of the outer rotor (2). A plurality of air vent through-holes (8) are formed each at a location close to the delivery passage (20) with a predetermined distance therebetween in a circumferential direction for communicating an inner space defined in the outer rotor (2) to the negative-pressure chamber (6). A shield member (21) is formed on the inner rotor (5) for intercepting the air vent through-holes (8) from the negative-pressure chamber (6) except for those located in a predetermined region opposite the delivery passage (20).

摘要： In the case of a device for open-end rotor spinning with a spinning rotor, the spinning rotor is provided with a fiber collecting groove and a fiber sliding surface. The fiber sliding surface is provided with structured areas which are set in the opposite sense of rotation to the spinning rotor, viewed in the direction towards the fiber collecting groove. The mouth of a fiber feed duct is disposed facing the structured areas with a component in the sense of rotation of the spinning rotor. Due to the way they are arranged, the structured areas, which cross the path of the fibers, exert a propelling force on the fibers in the direction of the fiber collecting groove. The sliding of the fibers into the fiber collecting groove does not take place exclusively by means of the centrifugal forces anymore, so that in design the traditional angle of taper of the fiber sliding surface is not necessary.
摘要翻译：在使用旋转转子进行开放转子旋转的装置的情况下，纺丝转子设置有纤维集合槽和纤维滑动面。纤维滑动面设置有结构化区域，其在朝向纤维收集槽的方向上被设置成与纺纱转子相反的旋转方向。纤维供给管道的口部设置成与纺纱转子的旋转方向相对的结构化区域。由于它们被布置的方式，穿过纤维的路径的结构化区域沿纤维收集槽的方向在纤维上施加推进力。纤维进入纤维收集槽的滑动不仅仅通过离心力进行，所以在设计中，纤维滑动面的传统的锥形角度是不必要的。

摘要： An open-end spinning machine has spinning stations and a magnetic and gas bearing with a stator at each of the spinning stations. A shaftless spinning rotor being electrically drivable with a single motor includes a series of spinning cups with different properties at each of the spinning stations for receiving fibers to be spun, and an electric rotor at each of the spinning stations forming an axial field motor with the magnetic and gas bearing and the stator. The spinning cups and the electric rotor have axially opposing end surfaces, and the end surfaces of the electric rotor and of one of the spinning cups at a time are coupled together to form a functionally appropriately releasable connection as a structural unit at each of the spinning stations.

摘要： The chiplessly formed open end spinning rotor (1) has, in the region of its collecting groove (11), a surface which has not been contacted by shaping tools. To produce it, a pot (3) is first made by stretching and stamping of flat material. This is then secured in its radial position independently of shaping tools. The peripheral wall of the pot (3), in the region between the later collecting groove (11) and the open edge of the pot (3), is upset inward by any optional kind of plastic deformation and the region later to be the collecting groove (11) by unsupported plastic deformation ["against air"].
