  • Patent number: 4958507
    Abstract: Process for making a sock of the type with two layers. A first course knitted by the needles, and corresponding to the end of the tip of a first layer, is transferred onto the central transfer plate of the machine where it is maintained in standby. Knitting of the first layer is continued, from the tip to the mock-rib edges. Then knitting is continued from the mock-rib edges of the second layer up to the tip, the knitted tubular structure being constantly suspended, by one (circular) end, from the central transfer plate and, by the other circular end, from the needle cylinder in the course of work, thus shaping the two concentric layers engaged in one another. The initial course in standby on the plate is transferred to the needles of the cylinder to effect join of the two layers to form one sole terminal layer.

  • Patent number: 4244197
    Abstract: Method and apparatus for knitting fleece fabrics on a knitting machine having two sets of needles disposed for movement in planes disposed at angles to each other to form a fabric construction; and wherein one set of needles is employed exclusively to knit a jersey ground construction from relatively lightweight yarns, while selected of the other set of needles are employed with selected needles of said one set to inlay a much heavier yarn along selected courses to pass alternately over and be tucked under groups of one or more consecutive wales of the knit ground construction without forming stitches therein. The heavy inlay yarns are drawn by the selected needles of the other set to appear primarily on one face of the fabric, and these selected needles which hold the inlay yarn are retracted to less than full welt position to dispose the inlaid yarn below the plane of knitting movement of certain of the needles of said one set.
