摘要： An open-end spinning device has a spinning rotor with a rotor pot defining a fiber collection groove therein. A rotor shaft is provided having a diameter between 5.5 mm and 9 mm. Pairs of rotatable supporting rings supported on axles define a nip therebetween. The rotor shaft is rotatably supported in the nip. The supporting rings have a diameter between 62 mm and 82 mm. A thrust imparting device imparts an axial thrust to the rotor shaft in the direction opposite the rotor pot. A non-contacting axial bearing is disposed opposite the free end of the rotor shaft for absorbing the axial thrust without contacting the rotor shaft. The axial thrust imparting device generates an axial thrust between 1N and 7N on the rotor shaft. A driving device contacts the rotor shaft for rotatably driving the rotor and has a contact pressure with the rotor shaft from between 8N and 39N.

摘要： 1282820 Track systems BORGS FABRIKS AB 29 May 1970 [6 June 1969] 26106/70 Heading B7L In a track system in which the direction of movement of the carriage 8 may be reversed, two parallel tracks formed by secondary rails 1 and 2 and a primary rail 3 are connected by an outer arcuate rail 17 and a pivoted rail portion 5, the centre of the arc of 17 coinciding with the pivot axis 4 of the rail portion 5, the arrangement being such that the wheels 6, 7 on one side of the carriage 8 may be supported by the pivoted rail portion 5 while the carriage is driven, by chain drive 13, around the arcuate rail 17. A catch device 14, which may be controlled for example by an electromagnet, locks the rail 5 to rail 3 until the wheels 6, 7 are in position on the rail 5. Guide rails 9, 10, 16 are provided for guide rollers, Fig. 2 (not shown), of known construction on the wheels of the carriage. Fig. 3 (not shown) shows an embodiment in which the direction of movement of the carriage may be rotated through angles less than 180 degrees.

摘要： A movable cleaning device is provided for cleaning the individual rotors on spinning assemblies of an open-end spinning machine. In order to accommodate cleaning of the rotors, with the rotor shafts being out of driving contact with their operational drives, the cleaning device is equipped with braking and/or driving means for controlling the rotational speed of the spinning rotor during cleaning operations. In this manner, cleaning elements such as rotary brushes, can be held in one position, while the relative rotational movement of the spinning rotor and the brush effects cleaning of the rotor. In certain preferred embodiments, the cleaning brush itself serves to impart rotational movement to the spinning rotor, with the drive for the brush being controllable so as to assure differential velocity of the brush and spinning rotor rotation. In other preferred embodiments, separate drive mechanisms and/or brake mechanisms are carried by the cleaning device for selective engagement directly with the spinning rotor.

摘要： 1430662 Open end spinning, spindle drives J M NOGUERA 19 Sept 1974 [21 Sept 1973] 44502/73 Heading D1D In an open spinning apparatus the opening roller 30 is mounted on a shaft 4 carrying drive rollers 3 for the rotor shaft 2. The drive rollers 3 may be mounted on two shafts or on a single shaft (Fig. 4 not shown). The drive rollers 3 may be mounted on an armature shaft of an electric motor. The drive roller shaft 3 which carries the opening roller 30 may be driven via the rotor shaft 2 from another drive roller shaft. The rotor shaft may be held against the drive rollers by springs or magnets.

摘要： High speed spindle for yarn winding directly onto the spindle is of one-piece construction. Its base portion is driven by a friction roller, which together with two supporting and stabilising rollers are placed in triangular formation around the spindle. Each of these rollers is in the form of a central shaft with end discs of a material of high frictional properties in contact with the spindle. The diameter of the spindle is smaller than that of the drive roller and drive is by an endless belt. Speeds of 60 to 100,000 r.m.p. are possible. The entire spindle may be removed to permit the fully wound spindle to be replaced by a bare spindle.
