ABSTRACT:
A tufting needle construction in which the mounting shank is offset from the axis of the blade and the yarn guide groove which extends to the eye and point portion of the needle. The yarn guide groove extends from a yarn entry mouth spaced from the shank so that yarn entering the groove from the mouth lies entirely within the groove and does not feed into the groove at an angle. Accordingly, when the needle pierces a backing material during the tufting process, the yarn is not crushed between the blade and the backing material. In one embodiment the shank is perpendicular to the blade. In another embodiment the shank has a first portion perpendicular to the blade and another portion parallel to the blade.
