An improved system and associated method is disclosed for positive feeding of multiple strands of yarn from spools using a single motor drive within a hose reinforcement knitting machine of the type having a central knitter head with reciprocating needles that stitch a reinforcement web pattern around flexible hose moving through the central axis of the machine. The positive yarn feeding system comprises a feeder head assembly attached to rotating framework of the knitting machine coaxially with the knitter head. The feeder head assembly includes a circular support plate having an axial opening therethrough and a plurality of positive feeder units, one for each of the yarn strands intended for knitting. The feeder units are arranged in a radial pattern about the periphery of the support plate and interconnected for concurrent rotation by a coupling belt extended about upper wheels on the units. The feeder head assembly further includes a central gear mounted in a stationary position atop the support plate, a planetary gear rotatably mounted upon the support plate in position to engage the central gear, an adjustable control gear secured atop the planetary gear, and a drive belt engaged about the control gear and a proximate one of the feeder units to provide the rotational drive for all. As the single motor drive rotates the framework of the knitter machine and its mounted spools, the feeder head assembly rotates in unison and by means of the combined arrangement of interconnected gears assembled thereto, synchronizes the drawing of the yarn strands through the feeder units and into the central knitter head.
