  • Patent number: 5133196
    Abstract: In a circular knitting machine of the type in which the needles are selectively moved into and out of operative relationship with needle cam tracks, flexure of the lower portion of the needle shanks properly locates the lower end portions of the needle shanks in close proximity to selection devices. Such flexure is effected by a plurality of individually radially displaceable rollers. The rollers are disposed in rolling engagement with the outer surface of a flexible band which, in turn, is positioned around the needle cylinder in closely encircling relationship to the needle members at a point below and on the opposite side of a fulcrum located adjacent to and near the upper end of the needle members. As the needle cylinder rotates, the rollers are engaged by cams and displaced toward the needle shanks. The rollers thus engage and inwardly displace portions of the band and thus the needle members therebehind, effecting movement of the needles into close proximity to the selection devices.

  • Patent number: 4674301
    Abstract: A process for operating and controlling compound needles that have reciprocal travel of the needle and slider restricted by abutment surfaces where the needle is lifted high enough to engage yarn but less than the travel of the needle and slider and the descent of the needle. Before the needle descends, the needle is lifted selectively to bring the upper end of the slider above the plane of knock-over of the sinkers through the action of abutment between the needle and slider. Needle descent takes place along at least two successive slopes in a track with different descent inclinations, the second slope being the steeper. Slider recall by the needle begins before the needle is brought down again by the second slope. Improved stitch-forming cams to permit compound needles to operate in accordance with the foregoing process are disclosed also.

  • Patent number: 4314461
    Abstract: A knitting machine includes latchless needles, and selector elements located in positions corresponding therewith. Each selector element comprises a hook-like extension directed towards the needle point and arranged to penetrate into a longitudinal slot in the needle. The selector elements are subjected to sliding movements approximately perpendicular to the needles, together with lifting and lowering movements so that they penetrate into the needle slot, and are lifted in order to take-up the stitch engaged by the needle and to remove it therefrom. Alternatively the selector element can abandon the stitch by lowering its hook-like extension below the plane of formation of the fabric.

  • Patent number: 4122690
    Abstract: Method and means for transferring knit loops from single-hook needles on one cylinder to single-hook needles on the other cylinder of a double cylinder circular knitting machine. In the method and needles are displaced at an inclination outwardly of their cylinders to allow axial sliding of the opposing needles behind the inclined needles and into the loops held on the inclined needles; the inclined needles are then withdrawn to shed the hooks, which are then received on the hooks of the other needles. The means includes radial pins slidably carried in the cylinders for engagement and operation by stationary radial cams located within the cylinders, the pins extending through the cylinders and into engagement with the stems of the needles for radially displacing the needles outwardly to the inclined positions required by the described method.
