Abstract
The utility model provides a compound needle of a flat knitting machine. The compound needle can be reliably used for guiding a needle latch to sink into a slider groove during loop pushback. During loop pushback, a slider with a needle latch which is formed by two blades is pushed back relative to a needle body. During loop pushback shown as an accompanying drawing (b), a rear part (16c) is uplifted by a cam (12e), and a swing component (16) swings by taking a clamping part between a lower swing joint (16a) and an upper swing joint (15c) of a basal body (15) as a fulcrum. The blades (14) are lowered down, the needle latch (14a) sinks into the slider groove (12c), a loop can be successfully pushed back along a needle bar (12b). Since the cam (12e) is arranged at the rear of the slider groove (12c), the influence of processing for forming the slider groove (12c) is avoided and the width of the formed slider groove can be equal to the width of the needle body (12). Moreover, the swing component (16) which is driven by the cam (12e) is enabled to be thicker than the blades (14) and therefore the compound needle can be reliably used for uplifting to enable the needle latch (14a) to sink into the slider groove (12c).
