Abstract
The present yarn feeding device includes a rotating yarn feed wheel with at least one frictional yarn engaging and driving surface of predetermined width around the peripheral surface thereof, and yarn guides are provided for directing two runs of the yarn into engagement therewith. Movable yarn guides are provided for varying the degree of circumferential engagement of the individual runs of the yarn with the frictional yarn driving surface so that the degree of engagement is sufficient to cause the yarn to be fed when the knitting machine makes a demand for yarn and so that the degree of engagement is insufficient to cause the yarn to be fed when the knitting machine ceases to make a demand for yarn. A pair of manually movable yarn guide members is supported in spaced relationship from the outer circumference of the frictional yarn driving surface. The manually movable yarn guide members are manually adjustable in radial directions to vary the degree of circumferential contact between the individual runs of the yarn and the frictional yarn driving surface to permit yarns of different frictional characteristics to be fed by the yarn feeding device.
