Abstract
A knitting needle for use in knitting machines. The needle includes a shaft and a butt extending from the shaft for being received within a cam track of a knitting machine. The butt has a pair of substantially parallel side faces aligned with the needle shaft and upper and lower edges extending between the side faces. A medial face extends along a medial portion of each upper and lower edge of the needle butt between the side faces. A pair of angled faces extends between each medial face and side face to interconnect the medial face and side faces. The angled faces have an inclination angle approximately equal to the maximum inclination angle of the cam of the knitting machine in which the knitting needle is used. Each medial face may be arcuate in shape and the angled faces may be tangent to each associated arcuate face. Alternatively, the medial faces may be substantially planar and substantially perpendicular to the side faces of the butt.
