A vibration friction feed wheel mechanism for feeding thread to a thread processing machine having intermittent thread requirement. The feed wheel mechanism including a high friction contact surface, a thread guide level for lifting thread off of the feed wheel and a vibration generating arrangement for applying a vibrational movement to the thread. The vibration of the thread ensures that the thread lifts-off from the contact surface of the friction feed wheel by reducing the coefficient of friction between the thread and the high friction contact surface of the friction wheel.

A spool rack ( ) composed of carrying and connecting struts includes a connecting system for the struts connecting element ( ) which are inserted in each case into one of the struts. The connecting element has a pressure transmitting portion ( ) against which there is supported a screw bolt ( ) which is screwed into the threaded socket ( ) of the other strut to be connected. To enable mounting in correct position, the connecting element ( ) is releasably fixable in the corresponding strut.

A feeder device for feeding elastomer yarns in knitting machines has a housing split into two parts, on which bearing and drive rollers are rotatably supported, spaced apart from and parallel to one another. The housing encloses an internal chamber that accommodates gears for driving at least one of the bearing and drive rollers. The gears transmit force from a drive wheel, which is secured to a shaft protruding from the housing, to at least one bearing and drive roller. The bearing and drive rollers are supported via ball bearings, which are retained by corresponding bearing seats provided in the housing. The bearing seats are recessed in the respective integrally formed housing parts, which are preferably made by injection molding. The dividing line at which the housing parts border on one another extends through all the bearing seats, so that the ball bearings are retained between the housing parts. Securing the housing parts to one another fixes the ball bearings as well, simultaneously.
