Abstract
A conventional tufting machine is provided with a looper control cam which enables it to sew chain stitched tufts. The cam reciprocates loopers which face in a direction opposite to the direction of movement of the backing material, the looper being reciprocated once for each reciprocation of the needle. Each looper catches and holds the bight of the loop being sewn during the period of maximum penetration by the needle and then moves the bight of that loop beyond the needle so that the needle sews the next loop through the held loop, the looper releasing the held loop and catching the inserted loop, thereafter.
