The cams are the one which commands the various needles movement. Needle butt moves between the grooves of cams. The shape of the needle cam grooves depends on the required knitting pattern. The cams are placed outside the needle-bed; each feed system is provided with its own cam group. In Double-bed, two cam frames, one around the cylinder and the other above the dial. All the cams are fixed to a bearing structure called “cam frame”. On single-bed machines, the cam frame is stationary, while the needle-bed revolves.
