Abstract

A yarn traversing apparatus for reciprocating a running yarn to form a wound yarn package, and wherein the yarn is reciprocated by sequential contact with oppositely rotating rotator blades. The blades can each be driven at a variable rotational speed, so that irrespective of the position of the yarn radially along the length of the rotator blades, the traversing speed of the yarn can be controlled so as to follow a predetermined traversing speed profile, which may be constant or variable.
