ABSTRACT:
A yarn tensioning device which is arranged to impart a high unwinding tension to a feed yarn in a yarn draw-out phase of operation and to impart a low unwinding tension with a large yarn draw-back capacity. The yarn tensioning device is is particularly suitable for use on a textile machine which is arranged to produce at three-dimensional fabric by interweaving a large number of yarns 24 fed from yarn carriers 20 which are driven by a carrier drive mechanism to shift the respective positions along predetermined loci of movements within a common carrier shifting plane. Mounted on each carrier 20 is a high tensioning mechanism which acts with a small yarn draw-back capacity and a high yarn tensioning capacity for a feed yarn 24 being unwound from a bobbin 23, in combination with a low tensioning mechanism 22 which acts on the feed yarn with a large yarn draw-back capacity and a low tensioning capacity. As a result, a high yarn tensioning force is applied to the feed yarn by the high tensioning mechanism 21 in a yarn draw-out phase of operation, and a low yarn tensioning force is applied to the feed yarn by the low tensioning mechanism 22 in a yarn draw-back phase of operation past a limit point of yarn draw-back by the high tensioning mechanism 21.
