ABSTRACT:
Two blades (14, 14) of a slider of a compound needle move back into blade grooves (8, 8) of a needle body (4) on the left and right side of a partition wall (9). An opening (18) is provided at the front ends of the blades (14, 14), and curved portions (19, 19) are provided on the backside of the front ends of the blades. Further, a thick section is provided at the front end of the partition wall (9), and a thin section is provided on the backside of the thick section.When the blades move forward from the blade grooves, the blades are centered at the thick section so that even if a lateral force is applied from a knitted loop to the blades, deformation of the blades is prevented by the contact of the two blades at the curved portions. In the blade grooves, the curved portions contact the thin section of the partition wall such that the force applied between the blades and the blade grooves does not increase.
