Method and apparatus for removing broken filaments

Abstract

A method and apparatus are provided for removing broken filaments from a continuous filament tow (60) traveling at a tow velocity between a source and a collector. The tow (60) is contacted with a rotatable, cylindrical roller (13), having an axis of rotation and an outer surface, located in the path of travel by the tow from the source to the collector. The axis of rotation is oriented generally perpendicular to the direction of travel of the tow (60). The roller (13) rotates in a direction counter to the direction of travel of the tow (60) to lift broken fibers from the tow. The lifted broken fibers are entrained in an airflow created by a tubular vacuum header (12) to remove the broken fibers from the tow.
