ABSTRACT:
An apparatus for controlling the tension on yarn withdrawn from a mass of compacted yarn within a confined space has a yarn guide element with a tubular wall portion defining a confined space for guiding and for accumulating a compacted mass of yarn, an inlet opening for entry of the compacted yarn mass into one end of the confined space and an outlet opening for allowing withdrawal of the yarn as a yarn bundle from the confined space. The outlet opening is an elongated slot that is provided in the wall portion of the yarn guide element and that applies tension to the yarn bundle withdrawn from the confined space. The slot has a preselected configuration so that the slot will vary the tension applied to the yarn bundle as the yarn mass moves from one end of the confined space to the other end.
