Abstract
In an apparatus for continuous draw-off of yarn from a package at a measured rate and under regulated tension, the yarn can either be passed to a waste receptacle for a predetermined length of time or can be metered to a scale for subsequent determination of yarn weight per unit length (denier). Diversion of the running yarn from one path to the other is achieved without affecting yarn draw-off rates and tensions.
