  • Patent number: 4070873
    Abstract: Method for knitting a sock, wherein for casting on the yarn the feeder is brought behind the knitting point, while the clamping means retaining the yarn end is before the knitting point as viewed in the direction of rotation of the needle cylinder, and after engagement of the knitting yarn by the first needles, the clamping means is moved to a yarn feeding position for knitting. After the first needle, one or a plurality of needles is brought into a position in which the yarn is not engaged at the knitting point, so that the yarn initially present between the feeder and the first needle is included in the fabric by the needles initially not engaging the yarn during the knitting of the subsequent courses.

  • Patent number: 3974525
    Abstract: In knitting socks in a string of such socks on a circular knitting machine, a double fabric is knitted in order to close the toe, further courses then being knitted with a heat-shrinking yarn, followed by knitting courses with a washable yarn, after which a start is made with knitting the welt of the next sock to be knitted. Thus by immersion of a string of such socks in a hot bath the washable yarn disappears to separate the socks and the shrinkable yarn shrinks to provide a run-free cast off.
