Abstract
A knitting machine has at least one needle bed equipped with longitudinally displaceable needles controlled by a needle cam curve, and between the needles are protruding sinkers controlled by a sinker cam curve. The sinkers are movably supported in at least the longitudinal direction of the needles and being controlled such that at a given feed, after the locking in of the yarn, they are moved counter to the lowering movement of the associated needles and after casting off of the loop are moved counter to the needle raising movement. The needle and sinker cam curves have adjoining steadily curved arc portions that in the case of the needle cam curve are sinusoidal and merge steplessly with one another. To reduce noise and wear, especially at very high knitting speeds, the sinker cam curve is substantially sinusoidal, at least in the loop forming zone.
