Wound filters of readily varied length are formed by applying yarn to a core on a winding machine utilizing a linkage system that changes the traverse length of the winding apparatus and concurrently changes the rate of change of direction in a ratio different than the ratio of change of traverse length in order to maintain adequately uniform tension during such winding. Such operation also provides for winding yarns of different dynamic characteristics. Apparatus for applying the filters so formed to a variety of support assemblies therefor act on the apparatus formed by such process and apparatus.
