  • Patent number: 6971326
    Abstract: The invention concerns a tufting machine having at least one needlebar, loopers, hooks to pick up yarn delivered through the needles of the needlebar, knives to cut yarn loops and driving means, with the needle action and/or the looper action and/or the hook action, and/or the knife action being a non-simple harmonic motion. In said machine the needles, the hooks, the knives and the loopers have separate drive systems. So the motion of the needles, the hooks, the knives and the loopers can be such that first of all the pickup of the yarn or the cutting of the yarn loop can be improved. When the drive system is computer controlled more accurate machine set up can be achieved. Moreover different set ups can be achieved automatically for different products. Patterning effects are also possible.
