ABSTRACT:
A knitting machine has at least one needle bed (1), which is equipped with needles (4) that are controlled by needle cam parts, (16), following along a needle control curve, and are guided longitudinally. Between the needles, sinkers (22) that are short in comparison with their length are supported on the needle bed, or on a sinker carrier (21) connected to it, such that they can be displaced in the longitudinal direction of the needles and essentially transversely to it, about a transverse axis. The longitudinal and transverse movements of the sinkers are controlled, in each case following along a sinker control curve, such that during at least part of the withdrawal movement of the needles, which is devoted to loop formation, they execute a projection movement contrary to this withdrawal movement. To enable changing the loop length easily, a needle cam carrier (14) carrying the needle cam parts (16) and a sinker cam carrier (12) carrying the sinker cam parts (30, 36, 37) are adjustable relative to one another, transversely to the needle longitudinal direction. The needle cam control track, and the sinker cam control track associated with the sinker longitudinal movement, have portions that are essentially aligned in the same direction.
