摘要

A method and apparatus for winding and twisting yarn onto a spool directly from an extrusion line or other production source by means of an inline twister. The inline twister comprises the following elements: a rotatable spindle, a bottom flange securely fastened to the spindle having a catch on the outer periphery, a removable interlocking top flange positioned on the spindle, means for positioning the spool concentrically about the spindle, a twister ring concentrically positioned about the spindle having a slit, and a rotatable traveler positioned on the twister ring having a hook inwardly directed toward the spindle.;The method of winding and twisting the yarn onto a spool comprises guiding the yarn adjacent to the spool. This yarn is then positioned adjacent to the slit in the twister ring and is allowed to pass therein. The spindle on which the spool is contained is then rotated so that the catch-equipped bottom flange contacts the yarn and holds it tight. As the yarn is rotated by the bottom flange it contacts the hook equipped rotatable traveler positioned on the twister ring and this combination of rotating flange and traveler provides the means for inserting twist into the yarn as well as wrapping the yarn about the spool. As the yarn is wound about the spool the twister ring is reciprocated so that the point of collection varies about the spool.
