  • Patent number: 4007611
    Abstract: A knitted yarn and a method for knitting the yarn. The yarn comprises two strands formed into successive stitches alternately disposed about two needle axes. Alternate strands form the successive stitches along each axis. Each stitch on one axis is drawn through a preceding stitch on that axis. As a result, each stitch on each strand passes through an adjacent stitch formed of the other strand.Each stitch in a strand is formed at a single or one of two reciprocating latch needles which pull the newly formed stitches in each strand through preceding stitches in the other strand and cast off the preceding stitches. Then the needles extend to accept the next stitches formed in the strands. The yarn knitting apparatus feeds strands at a controlled rate to service bars which reciprocate and oscillate over the needles to form the stitches at the needles alternately each time the needles reciprocate.
