[Class 120(iii)] [Also in Group XXIV] In apparatus for producing yarn having variations in denier along its length, a positive infinitely variable transmission 105 drives a cyclically varying speed gear 11 (see Group XXIV) which, in turn, drives. a pump 120 at cyclically varying speed. The outlet from the pump is connected by a conduit 124 to a spinneret 126 through which the composition is pumped for the formation of filaments. The feed wheel 133 is driven at a constant speed from the shaft 106 and draws the yarn from the coagulating bath.131.
