ABSTRACT:
A plurality of yarn feeding assemblies are mounted about a circular multifeed knitting machine. Each assembly comprises a U-shaped hanger bracket and a shaft is rotatably mounted in the arms of the bracket. On each shaft one or more yarn feeding units are mounted for rotation therewith about the shaft axis. Each unit is comprised of a pair of toothed wheels, one of the wheels being fixed to the shaft and the other one being axially movable along said shaft in order to vary the spacing the wheels. Means are provided for selectively varying the spacing between the front faces of the wheels. Each wheel is constituted by a plurality of radially extending circumferentially spaced apart ribs, the front faces of the ribs of one wheel facing the front faces of the ribs of the other wheel. The ribs of each wheel are receivable within the spaces between the ribs of the other wheel. The front faces of the ribs of the fixed wheel are substantially perpendicular to the axis of the shaft and the front faces of the ribs of the movable wheel are rearwardly and outwardly inclined relative to the axis. The edges of the front faces cooperate to produce outwardly opening bites. A yarn guide holder is mounted on the bracket for directing yarn from a yarn source into the bites of the yarn unit, around at least a portion of the unit, and then toward a knitting station. A feed unit is provided for each knitting station. The shafts are rotated synchronously with the knitting machine and the rate of feeding for each feed unit may be varied by varying the axial spacing between the wheels thereof.
