摘要： A belt tightening device is provided for open-end spinning machines which is capable of ensuring good belt thrust, eliminating vibrations, and reducing the noise level of the machine. Each bearing box of a belt tightening roll is attached to the end of a pair of flat legs extending in spaced apart relationship to each other along the endless driving belt. The legs are connected to the bearing box either by spring elements, or are formed themselves by leaf springs.

摘要： Resilient high-speed rotor support, especially applicable to rotor shafts open-end spinning machines. The support is made up of a double-row rolling bearing, a rotor shaft, and a central sleeve for the bearing, as well as resilient damping elements disposed at the ends of the central sleeve and fixed within the housing of the spinning mechanism. At the stepped ends of the central sleeve there are fixed resilient damping elements by means of their radially inner annular parts, the external circumference of the damping elements, reduced by the height of the limiting gap between them and the housing, extends to the circumference of marginal orifices within the housing. The bore at the rotor end of the central sleeve is formed with a tolerance to provide a running fit with the rotor hub. The support of the invention is applicable especially in spinning machines operating with rotor speeds exceeding 60,000 RPM.

摘要： A combing roller for use in a singling-out device of an open-end spinning machine includes a cylindrical body having a plurality of teeth formed on its outer circumference. Each of the teeth is formed by the intersection of at least one spiral circumferential groove with a number of recesses. The recesses are disposed on the circumference of the cylindrical body at an angle of up to 45 degrees relative to the direction of a force generating line which is parallel to a rotational axis of the cylindrical body.

摘要： High-speed spindle holder suspension in textile machines, particularly open-end spinning machines. The suspension includes a sleeve and a pin; between the contact surfaces of the sleeve and the pin there is mounted a resilient damping element made of low density polyethylene. Preferably the low density polyethylene has a molecular weight of about 106 and a hardness of 60 to 80 on the Shore durometer scale.
