发明名称 APPARATUS
摘要 A waste spool for use with a ring twister comprising a frustoconical body member having a pair of tabs extending outwardly from its top surface. The particular structural relationship of the tabs with the tapered surface of the body member, coupled with a specified taper of the body member, provide a starting location for the waste windings that will enable their easy removal as a circular yarn wrap over the end of the waste spool.
