Abstract

A yarn traversing mechanism having oppositely traversing yarn engaging elements and transfer means that disengage yarn from one element and transfer it into engagement by an oppositely traversing element at a plurality of different yarn reversing locations at each end of the yarn traverse. The different reversing locations are determined by an unequal spacing of yarn engaging elements and by either selectively raising a yarn guide member or displacing yarn engaging elements differently at different traversals of the yarn.
