Abstract: A loop forming and cutting apparatus for a tufting machine which comprises a looper having a forwardly directed bill, a slot disposed transversely through a substantial portion of the length of the bill, and a blade pivotally mounted to the looper, with the cutting edge portion thereof extending into the slot. Thus the lower edge of the bill and the cutting edge of the blade form a forwardly facing, scissors-like bight which acts to sever the yarn loops as they move rearwardly along the bill. Means are provided for terminating operation of the tufting machine when any one of the blades becomes dull.

Abstract: A tufting machine wherein the needle bar is reciprocated by a number of like, mounting assemblies which are positioned along the length of the machine, with each assembly comprising a number of linkage arms which are pivotally interconnected to thereby minimize friction and power consumption. Also, the reciprocation of the needle bar, which is guided by the assemblies, results in a pause at the bottom of the needle movement to facilitate pick-up of the yarn loops by the loopers, and the needles have a component of movement in the direction of movement of the backing fabric at the bottom of their stroke, whereby the needles function to deposit the yarn loops on fixedly mounted loopers. The machine further includes a yarn tension control arrangement which is readily adjustable during operation of the machine.
