Abstract
Lengths of yarn are bound together in the center to provide relatively short yarn bundles for use in forming yarn balls of the type usually referred to as 'poms.' A forming wheel is supported for rotation and includes equally spaced forming stations about the periphery for receiving yarns and arranging them into a generally parallel, composite arrangement. The wheel is indexed in a step-by-step manner a distance equal to the distance between successive forming stations and the composite arrangement of yarns is gripped and confined at each of the spaced forming stations. Binder elements are sequentially applied around the bundle of yarns as the successive forming stations move into alignment with a binder applying head. The bound yarns are then cut between successive forming stations to provide lengths of yarn bound together in the center and held in each forming station. The cut and bound together bundles of yarn are then successively stripped from the forming wheel and removed from the machine.
