ABSTRACT:
A method and apparatus for initiating feed of yarn on a machine for taking yarn from a supply, processing it and rewinding it. A short length of processed yarn is led back through a series of guide wires to a vacuum receiver for holding the free end of the yarn. The wire guides are actuated to form a large loop so that the processed yarn will be fed over the input roller and the output roller, so as to pick up yarn from the supply. The lower roller of the feed roller assembly is elongated to aid in the looping and lateral in-feeding of the processed yarn loop. The previously processed yarn, after it is fed around the input and output rollers and has picked up the additional yarn to be processed is pulled from the vacuum retaining system and incorporated in the processed yarn.
