Abstract
To insure gentle latch operation, and particularly gentle opening of the latch, the last-knitted loop (36) is constrained to move in the same direction as the needles (2) by controlling movement of sinkers (7) in the same direction as the needles, at a speed slower than needle speed during the raising phase of the needles (FIGS. 5, 6), so that initial movement of the latch occurs slowly and not abruptly to permit faster knitting speeds by reducing stresses on the latch. Conversely, during closing movement of the latch (FIGS. 9, 10), initially, the loop and the needle are lowered simultaneously, the lowering speed of the loop, controlled by the sinker (7) being slower than the lowering speed of the needle. Cast-off can be improved by rapidly controlling the loop by suitable sinker movement (FIGS. 11, 12). The projection distance of the needle can be decreased to at most that of the latch motion distance by constraining the loop, held on a sinker as well as on the shaft of the needle, to a position below the rest position of the sinkers by suitable construction of the sinker cam (15, 15a, 15b; FIG. 2).
