摘要：A multiply effect yarn is wound up from a plurality of strands on a yarn-windingbody that is rotated at a variable predetermined speed. Each of the strands is fed via arespective strand-feed element to the yarn- winding body. The feed rate of each of thesestrand-feed elements can be individually varied, and is established as a function of therotation rate of the yarn-winding body to maintain a predetermined proportionalitybetween the various speeds. The drive for each strand- feed element comprises aseparate pair of variable-speed motors set to operate at different speeds and operatedby forward and backward counters so that either the one motor or the other motor ofeach drive is connected to the respective feed element which can also be connected to abrake, if desired. The various speed rates can rapidly be adjusted, in accordance with theoverall drive rate for the yarn-winding body, even during production of the multiplyeffect yarn.
