Abstract
Self actuating yarn feeding apparatus to feed yarn to a circular knitting machine when the machine makes a demand for the yarn and to cease feeding the yarn when the machine ceases demand for the yarn. The yarn is in variable circumferentially extending drive contact with the periphery of a frictionally surfaced rotating yarn feed wheel to feed the yarn to the machine. The arrangement being such that when there is a lack of demand for the yarn the degree of contact between wheel and yarn is not sufficient to feed the yarn and when there is demand for the yarn the degree of contact between wheel and yarn is sufficient to feed the yarn to the machine. The yarn extending through a yarn eyelet movable back and forth along a circular pathway in response to demand and lack of demand for the yarn by the machine to vary the degree of contact between wheel and yarn.
