<p>A weft knitting machine capable of altering wale density in any wale over each course. The machine includes needle selecting actuators (10), (11) for selecting the position of a knitting needle (40) brought upwardly to a knitting or tacking position, selecting jack pressers (6), (7), (8), (9) for lowering, to a lower position, a butt (36) of a selecting jack (30) for operating a jack (37) corresponding to the needle (40) which has been selectively raised to the knitting or tacking position by the actuators (10), (11), and knitting cams (2), (3) for actuating a high butt knitting cam (56) in a butting contact with a high butt above a double close lap and for actuating a low butt knitting cam (57) in a butting contact with a low butt below a double close lap. The machine conveniently alters the density of the knitted fabric by varying the lowering position of the needle (40) via the knitting cams (2), (3). </p> |
