A linear course of thread is required for a high speed friction false-twisting unit. For this purpose, the region of travel of the thread through the center of a three spindle disk set triangle should be freely accessible. One of the disk sets is adapted to be swung out on a lever from the other two disk sets. A toothed belt drive is used both in the case of a tangential belt drive and in units driven by an electric motor. A further advantage is that this arrangement can be used in units which have the possibility of a change of the center-to-center distance. The belts from driving rollers which drive the disk set spindles are held outside the center of the disk triangle through which the thread passes.

A textile machine has a support carrying a number of yarn dispensing spindles. The machine includes an automatic winding device movable selectively to each of the spindles for rewinding yarn on each spindle. The winding device includes a yarn supply and elements which guide the yarn to the spindle to be rewound. In one embodiment, the winding device includes an articulated arm which removes the spindle from the support, brings it to the winding device for yarn to be rewound upon the spindle and returns the spindle to the support. In a second embodiment, an empty spindle is removed from the support by one arm and a second arm delivers a full spindle to the support. In a third embodiment, the automatic winding device moves to a spindle. Then a motor associated with the respective spindle operates at a different rewind speed and yarn is supplied to the spindle spinning at rewind speed to wind the yarn upon the spindle. Upon completion of rewinding, the spindle motor operates the spindle again at the yarn dispensing speed.

The jacket enclosing a motor driven textile spindle of the type wherein the spindle is driven by a separate motor which is mounted on a common base with the spindle is modified to include air inlet and air exit openings. The motor is located in proximity to the spindle and is coupled to it by a toothed belt or the like. As the spindle is rotated by the motor air is drawn in through the inlet opening of the spindle and exits through the exit openings in the form of a strong stream of air which blows on and cools the motor. In this manner the spindle doubles as a fan for the motor and the necessity of providing a separate fan for the motor is avoided, resulting in savings in space and energy for driving a fan.

The disclosure concerns an anti-friction bearing between a rotating shaft and an external bushing. The bearing includes two axially spaced apart rows of bearing balls. A feed bushing is disposed in the space between the shaft and the external bushing and between the two rows of bearings. The feed bushing is open at the axial ends for dispensing lubricant to the rows of bearings at the axial ends of the feed bushing. The feed bushing holds lubricant, such as grease, in itself for being dispensed at the axial ends of the feed bushing. A porous elastic material may be disposed in the feed bushing for being impregnated with the lubricant. The feed bushing, and also the porous material if used, are elastic and resilient to permit deflection of the shaft with respect to the external bushing. Various shape and configuration feed bushings are disclosed. A lubricant recharging hole passes through the external bushing and communicates to the feed bushing.
