Abstract:
Utilizing the principle of shogging pile yarns above and across warpwise extending pile formers or wires in the weaving of pile fabrics this invention is directed to a method and apparatus in which a plurality of weftwise rows of vertically movable and weftwise movable pile yarn guides are employed and wherein the rows of pile yarn guides and the respective pile yarns are shogged weftwise varying amounts independently of each other under control of a pattern mechanism.
Abstract:
This invention is directed to a variety of fabrics in which sets of warpwise extending pile yarns, preferably of different visual characteristics, extend weftwise over one or more groups of ground warp yarns to form warpwise rows of pile in the form of straight or oblique lines of pile, with the pile being in the form of loops or cut pile tufts of the same or different sizes and arranged in any desired pattern. Also, by floating at least one set of pile yarns, certain areas of the fabrics may be of lesser pile density, with such floating enhancing the variety of color effects obtainable.
Abstract:
The apparatus includes cooperating tufting needles, pile formers and latch needles for forming pile tufts on a backing fabric while positioning small locking threads through lower bight portions on the tufts being formed to secure them to the backing fabric. To permit the use of less pile yarn for obtaining any given height of pile on the upper face of the backing fabric, the tufting yarns are under relatively high tension so that they are drawn upwardly relative to the backing fabric and so that portions of the locking threads passing through the lower bight portions are displaced upwardly into the backing fabric. Also, novel means are provided for guiding the locking threads into the hooks of the latch needles each time they enter through the tuft lower bight portions so that the latch needles will draw corresponding stitches of lockin thread through the respective lower bight portions.
