ABSTRACT:
A jacquard pattern control mechanism for a circular knitting machine in which knitting instrumentalities are selected in accordance with a jacquard pattern and are moved between three positions, namely, welt, tuck and knit positions, by a selector jack, a rocker base, a rocker bar pivotally mounted on the rocker base and control cams for controlling the knitting instrumentality, selector jack, rocker base and rocker bar and electromagnetic selection mechanisms that attract selected portions of the rocker bar to determine to which position the knitting instrumentality will be moved, and wherein the selection mechanisms are more compact and have shorter strokes to permit selection of all types of knitting instrumentalities and all three positions without reducing the number of yarn feeds.
