  • Patent number: 4644763
    Abstract: In a knitting machine, electromagnetically controlled selector stations cooperate with sliding devices to enable them to assume two different positions. The sliding devices act in pairs on each needle of the knitting machine, and fixed vertical cams act on so-called two-arm levers to release them after selection, with the two-arm levers being retained or not by the sliding devices. Provision is made so that the two-arm levers can be oriented in four different positions. Each pair of sliding devices is composed of a first lower selector and a juxtaposed second lower selector, each of which can be moved into two different positions so as to produce the different four positions of the two-arm levers, in this way the needles may be controlled individually into tucking, out-of-action, standard knitting, and lengthened stitch knitting positions.

  • Patent number: 4612786
    Abstract: A latch-type needle for transferring stitches has a needle shank and lateral clip that define a space, and the shank and clip are each provided with an oppositely arranged protrusion that extend into the defined space. In a stitch transfer operation between a so-called reporting and a so-called receiving needle a closed latch of the receiving needle is lifted and opened by interaction between the latch spoon of the receiving needle and the inner protrusions of the needle shank and clip of the reporting needle, whereby smooth opening of the latch during stitch transfer is accomplished.
