Abstract
A substantially lightweight tufting needle bar and needle bar assembly of improved construction comprising preferably a hollow needle bar including a needle bar insert pin plate or base type portion having vertical bores for receiving needles. Horizontal bores intersect with the vertical bores to permit the insertion of roll pins which secure and lock the needles in place. The needles are horizontally grooved to enable precise securement by the roll pins. In the hollow needle bar embodiment, the outer channel of the needle bar is kept thin to provide an extremely light weight construction.
