摘要

The needle bar of a knitting machine, comprises grooves for housing the knitting elements, which are arranged adjacent to one another along the longitudinal direction of extension of the needle bar. Each groove (3) has a groove base (16), two groove sides (18, 19) and a groove opening (17). The groove has a larger width in the region of the groove opening than in the region of the groove base. The side of the groove is arranged at a right angle to the frontal side of the needle bar. Both the sides of the groove have surfaces that are inclined or curved towards one another. The needle bar of a knitting machine, comprises grooves for housing the knitting elements, which are arranged adjacent to one another along the longitudinal direction of extension of the needle bar. Each groove (3) has a groove base (16), two groove sides (18, 19) and a groove opening (17). The groove has a larger width in the region of the groove opening than in the region of the groove base. The side of the groove is arranged at a right angle to the frontal side of the needle bar. Both the sides of the groove have surfaces that are inclined or curved towards one another. The transition from the region of larger width to the region of the smaller width takes place along a surface, which extends along a part of the depth of the groove and which is inclined or curved towards the sides of the groove along the direction from the groove opening to the groove base, with respect to the other sides of the groove. The surface extends into the base of the groove. The inclined surface has two sub segments with different angles of inclination. Both the sides of the groove have surface segments, which run parallel to one another, in the region of their largest width. In the groove, a knitting element (5) is inserted, which has a fastening segment, which is arranged in the groove and which has a front side, rear side and two lateral sides. The fastening segment has a larger width in the region of the front side than in the region of the rear side. The lateral sides in sub segments have the same alignment as that of the surfaces of the groove sides. The knitting element protrudes out of the groove by a pre-specified projection. Pre-specified safety spacing is arranged between the groove base and the rear side of the knitting element.
