Abstract
A central stitch length controlling apparatus for simultaneously varying the length of stitch loops being knit and optionally the positioning of the yarn guides (31) in a multi-feed circular knitting machine. The apparatus includes a vertically adjustable inner knitting cam block support ring (6, 47) which supports the knitting cams (7) and optionally the yarn guides (31) thereon. A plurality of sprocket wheels (18, 38) is disposed around the inner knitting cam block support ring (6, 47) and a fixed outer ring (16, 43). Rotation of the sprocket wheels (18, 38) selectively raises and lowers the inner knitting cam block support ring (6, 47). A sprocket chain (19, 46) drivingly interconnects the sprocket wheels (18, 38) to each other and may be manually rotated for simultaneously imparting like rotational movement to each of the sprocket wheels (18, 38) to thereby selectively raise or lower the inner knitting cam block support ring (6, 47) and the knitting cams (7) supported thereby.
