Abstract
The present invention is an improved yarn feeding device which continuously forms yarn coils from a yarn package on its conical shaped winding body and then feeds the yarn to knitting machines with low and constant tension. A taper angle of the winding body is optionally adjustable according to the stretchability of the treated yarn for pushing the yarn coils smoothly toward a knitting machine.
