Looper apparatus for equalizing the legs of cut pile tufts

---

Abstract

---

A looper apparatus for a multiple needle tufting machine in which the bill of each cut pile hook is shaped to have a rear straight cutting portion and a free end portion transversely offset from the cutting portion to seize a loop from a corresponding needle and guide the loop along a path offset from the normal longitudinal row of stitching in order to extend the side of the loop on the cutting side of the hook so that, when the loop is cut, the legs of the cut pile tuft will be substantially equal.
