ABSTRACT:
A knitting needle for a chainstitch knitting machine is disclosed wherein protuberances are introduced into the shank of the needle in order to prevent the needle from changing its position within a groove of the needle bar so that the needle hooks maintain an even distance between each other to avoid flaws in the knitted material such as striping. The protuberances are impressed into the material of the shank of the needle by pressing tools. In one embodiment, three protuberances are pressed into the shank to thereby create a three point abutment on one side of the shank against one wall of the groove, while the other side of the shank abuts against the other wall of the groove. In another embodiment, wave-like through bends are created which create linear bends normal to the longitudinal extent of the needle shank. this will assure a linear abutment of the protuberance against one wall of the groove rather than a point contact. In another embodiment, a longitudinal bend or elevation has been introduced in a longitudinal extent of the needle shank assuring a longitudinal contact with one wall of the groove. All embodiments assure that all needles cannot elastically deform in the middle of their respective shank or cannot move to an oblique position within a groove.
