ABSTRACT:
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.
