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.
