  • Patent number: 5477707
    Abstract: A sinker having a sinker body and a butt for engaging a sinker cam. Upper and lower nibs protrude from the sinker body. A first throat is defined between the upper and lower nibs for receiving a yarn. First, second and third knitting platforms are defined by the sinker body beneath the lower nib. A second throat is defined by the lower nib and the second and third knitting platforms for controlling a yarn loop. The second platform may be closer to the first throat than the first platform, and the third platform may be closer to the first throat than the second platform. This progressive displacement of the second and third knitting platforms provides for quick rolling over of a needle latch due to the resultant elevated position of the yarn loop on the needle shaft at desired prints in the knitting operation. This advantage reduces dropped stitches, enables use of a shorter needle latch length while maintaining a desired stitch length at the tie-in, and facilitates higher machine operating speeds.

However, the lifting cam, which is retracted to clear the short butt needles as they pass by, further elevates the long butt needles to the uppermost level where they grasp both the terry yarn and the body yarn as they are lowered by the center cam.

  • Patent number: 4010626
    Abstract: Knitted underwear, such as panties, panty hose, leotard and the like formed with a terry patch simultaneously knitted with the fabric at the crotch or other areas. The garment is made on a circular seamless hosiery knitting machine. The resulting tube is tailored for the leg openings, then sewn to form the garment. Shaping of the terry patch is effected by using the usual needle selecting device, normally employed for heel patch reinforcement and modified with suitable cams. The machine is modified to use new dial elements, a new throat plate and a new manner of feeding the loop forming yarn and the base yarn above and below the plane of the dial elements respectively. The machine is operated in a new way and can also produce knitted fabric with eyelet pattern.

  • Patent number: 3986371
    Abstract: A method for forming loops on a circular knitting machine having a plurality of needles and sinkers alternately arranged in cooperation with each other. The sinkers are supported on a rotatable ring located exterior of said cylinder, and have a yarn engaging edge extending perpendicular to the needles and a heel at its opposite end. The steps comprising feeding a yarn to the needles, while sequentially moving the needles downwardly within the cylinder to draw the yarn. Simultaneously engaging the sinkers at their heel ends and advancing each of the sinkers toward an associated pair of needles along a straight line direction at an acute angle to the needles synchronously as the needles move downwardly. Thereby the yarn engaging edge is moved vertically upwardly while the edge is maintained perpendicular to said needles. The edge thus engages the yarn and cooperates with the associate needles to form loops from the yarn simultaneously on the associated needles and sinker.

    Abstract: A method and means for improving quality of terry fabric by controlling the position of terry loops as they are cleared on the needles. A special sinker actuating cam assembly is arranged to withdraw and then readvance the sinkers, after the terry loops have been drawn, to transfer these loops into their respective sinker throats prior to raising of the needles to clear height whereby clearance and subsequent avoidance of the terry loops by the needle latches are assured. Additional sinker cams for selectively changing the timing of sinker motion for bare needle makeup and, alternately, for knitting terry fabric, and for withdrawing the sinkers at the point of transfer are also disclosed.
