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.

Circular knitting machine with jacquard pattern control mechanism for

A cam mechanism and method in a circular knitting machine having at least two types of knitting needles each having a master butt and at least two selector butts and including a stitch cam for engaging the master butts and retracting the needles from the knitting and tucking positions to the stitch-forming level, and knitting, tucking and welt-guarding cams movable between extended operative positions and retracted inoperative positions, and a selection device for individually selecting and moving the knitting, tucking and welt-guarding cams between the operative and inoperative positions.

Cam mechanism for circular knitting machine and cam timing setting method

Each feed of the multiple feed circular knitting machine is provided with selector cams to position needles in one of four positions, knit, tuck, welt and early withdrawal positions. Two types of knitting needles are provided and each type of needle includes a master butt with a knite selector butt and a tuck selector butt. The selector cams are mounted on rotatable selector cam cylinders which are positioned to overlap each other to permit the selector cams to be arranged at the closest possible lateral distance from each other and to thereby permit an increased number of feeds to be positioned around the machine. The early withdrawal position of the selector cams is provided so that the dial needles do not interfere with the formation of stitch loops by the cylinder needles, when knitting on only the cylinder needles, such as when forming blister knit stitch constructions.
