Abstract
The invention relates to a tension control and compensation mechanism of a sample loom. The tension control and compensation mechanism is characterized by comprising a let-off support, let-off tension disks and a tension compensation mechanism, wherein a plurality of let-off tension disks for clamping warp yarn at certain pressure are uniformly distributed on the let-off support along the horizontal direction, and the tension compensation mechanism is installed above the let-off support. When the warp yarn tension is higher, a strip-shaped elastic sheet is bent to reduce the warp yarn tension so that the warp yarn tension keeps consistent, so that cracked ends caused by ultra-high tension are avoided. When the warp yarn tension decreases, a strip-shaped tension compensating sheet resets and unbends to return to the original position, and the warp yarn is tensioned so as to avoid the unclear shed. The structure is utilized for being matched with an original warp yarn system of the sample loom to realize the independent and stable let-off control on two or more types of warp yarn, so that the sample loom can be used for test weaving of seersucker, spandex fabric and patterned fabric, the test weaving range of the sample loom is expanded, and the equipment investment cost is reduced.
