ABSTRACT:
In a circular knitting machine of the type in which the needles are selectively moved into and out of operative relationship with needle cam tracks, flexure of the lower portion of the needle shanks properly locates the lower end portions of the needle shanks in close proximity to selection devices. Such flexure is effected by a plurality of individually radially displaceable rollers. The rollers are disposed in rolling engagement with the outer surface of a flexible band which, in turn, is positioned around the needle cylinder in closely encircling relationship to the needle members at a point below and on the opposite side of a fulcrum located adjacent to and near the upper end of the needle members. As the needle cylinder rotates, the rollers are engaged by cams and displaced toward the needle shanks. The rollers thus engage and inwardly displace portions of the band and thus the needle members therebehind, effecting movement of the needles into close proximity to the selection devices.
