    摘要: An open-end spinning frame (1) having a spinning rotor (3), whose rotor shaft (4) is supported, free of axial thrust, in the bearing wedge of a support disk bearing arrangement (5) and is fixed in place by means of a magnetic axial bearing (18). The axial bearing (18) has a stationary magnetic bearing component (27) fixed on the bearing housing (26), and a rotating magnetic bearing component (44) arranged at the end of the rotor shaft and having at least two annular shoulders (46) defined by recesses (47) in the rotor shaft (4). The sharpness of the annular shoulders (46) is reduced in the area between their outer circumference (58) and the adjoining radial faces (50) of each annular shoulder, e.g., via curved or beveled surfaces in such area, and the base surfaces (49) of the recesses (47) are each connected via rounded sections (51) with the radial faces (50) of the adjoining annular shoulders (46).

    摘要: A spinning rotor for use at high speeds in open-end spinning machines has a rotor cup having an annular wall portion defining a rotor opening, a bottom wall portion merging with the annular wall portion, and a mounting hub extending exteriorly from the bottom wall portion. A rotor shaft is affixed to the mounting hub coaxially with the rotor cup. The merger of the bottom and annular wall portions of the rotor cup defines a maximum exterior diameter of the rotor and an interior rotor groove. The annular wall portion, the bottom wall portion and the mounting hub are of different cross-sectional thicknesses with the cross-sectional thickness of the bottom wall portion increasing from the rotor groove to the mounting hub. The wall thickness is less than 1.2 mm in the area of the maximum exterior diameter of the rotor cup (2) and the rotor cup has an aerodynamic exterior contour free of edges for deterring turbulent boundary layer air flow thereabout and an interior contour for promoting fiber spinning into a yarn.

    摘要: An apparatus and method for determining characteristics of staple fiber yarn by measuring the change in the yarn diameter after twisting or untwisting of the yarn. The yarn thickness of a length of yarn is measured during a first measuring process and subsequently, by a second measuring process after the twist is released. The two series of values of yarn thickness or diameter can then be compared with one another to determine certain characteristics of the sampled yarn.
