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. The sinker butt may have spaced apart lateral cam engaging portions that are connected by a bridge so as to define an opening of substantially triangular shape having a vertex pointed toward the sinker body, so that the butt may withstand damage without causing further damage to the knitting machine due to breakage of a sinker butt.
