Abstract

An improved yarn feeder for knitting machines includes a frame, a feeding reel, a brake, a press block, a pulley, a holder, a transmission spindle and a yarn guide. The feeding reel includes a driven wheel which has a top flange with a center opening and a plurality of equally spaced rods extending downward from bottom surface of the top flange, and a driving wheel which has spoke like ribs each has a slot opening at a free end thereof for engaging with an elongated bar at a lower portion which has a “8” shaped crosssection. The driving wheel may engage with the driven wheel through the center opening with the top end of the elongated bar engaged with a cavity formed in the bottom side of the top flange between a pair of adjacent rods. The feeding reel and the yarn feeder may be made with greater precision at a lower cost than conventional yarn feeder.
