ABSTRACT:
A tufting machine has a plurality of needles, each needle having a pair of eyes and cooperating with a pair of loop pile loopers seizing loops of yarn from a respective eye. The needle has an elongated yarn receiving groove extending along the surface of the needle facing the direction in which backing material is being fed. Each eye opens into the groove for receiving yarn guided along the groove. The point of the needle is offset relative to the longitudinal axis of the needle so that the needle does not enter loops previously shed by the loopers when relatively high pile height fabric is produced. The loopers of each pair of loopers have bills which point in the direction the backing material is being fed, the bills converging in the direction in which they point. The loopers of each looper pair are laterally spaced apart and each looper of the pair enters a clearance above a respective eye for seizing loops of yarn presented through the eye. The needle and the looper pair cooperate to form a series of loop pile loops in a row which form a non-aligned array resulting in a non-linear appearance of the loops.
