ABSTRACT:
Self actuated positive yarn feeding apparatus for use with circular knitting machines for the positive feeding of yarns to the machines in response to and for the time that a demand for yarn is created by the knitting action of the needles of the machines, and wherein feeding of the yarn is discontinued in response to a lack of demand for yarn by the machines. Wheels having adjacent horizontally extending circumferential zones of high and of low friction surfaces are provided wherein only the high friction surfaces feed the yarn. A movable pair of yarn guiding eyelets is positioned between a fixed pair of yarn guiding eyelets and the wheel with the yarn threaded, in turn, through a fixed eyelet, then through a movable eyelet, then around the wheel, then through the other movable eyelet, and finally through the other fixed eyelet. The movable eyelets acts to shift the yarn between the high and the low friction surfaces in response to demand for yarn by the machines. The apparatus can be used on machines having yarn changer boxes, needle selecting means, or other devices needing non-uniform yarn feeding, as well as on machines needing uniform yarn feeding.
