Abstract
An apparatus capable of feeding a roll of yarn wound around a bobbin to a knitting machine without having to apply tension to the yarn is provided. In the yarn feeding apparatus, the bobbin mounting frame for mounting the bobbin into operation position is rotatably supported by one end of a linkage bar. The other end of the linkage bar is pivotably coupled to a fixed horizontal bar. A driving shaft is positioned beneath the bobbin mounting frame such that the circumference of the yarn roll comes into contact with the driving shaft. The bobbin is thus driven to rotate when the driving shaft rotates. With this arrangement, the feeding of the yarn to the knitting machine would be smooth and stable in speed. The drawback of having to replace a new roll of yarn before the old one is completely used up is eliminated.
