1. A machine for forming J-tuft cut pile comprising:
- a. means supporting a base fabric,b. means for stitching a yarn continuously through said base fabric to form substantially uniformly spaced loops therein,c. a hook having a free end to enter each loop, and a closed end,d. means for relatively moving each loop upon said hook toward its closed end,e. means cooperating with said hook to cut each loop on said hook, to form a leading strand of predetermined pile height and a trailing strand,f. backdrawing means cooperative with said stitching means for positively backdrawing said trailing strand, only after said loop is cut, a limited distance less than said pile height, to form said trailing strand within and projecting from the same side of said base fabric as said leading strand to a height substantially less than said pile height,g. a resilient clamping member, andh. mounting means fixing said clamping member relative to said hook and biasing said clamping member toward engagement with said hook, to permit movement of said loop upon said hook and to yieldingly hold said trailing strand on said hook, in order to control the uniform length of each trailing strand.

Abstract
The method and apparatus for stitching yarn continuously through a base fabric to initially form loops therein, cutting each loop to form a leading strand and a trailing strand, and selectively back-drawing the trailing strand after it is cut, to form J-tuft pile.

- 8. In a tufting apparatus for producing cut pile fabric having reciprocable needle means including a needle, and looper means including a looper having a bill, and a knife, said needle cooperating with one side of said looper to form a loop on said looper, said knife cooperating with the other side of said looper to cut a loop on said looper, a clamping member, mounting means fixing said clamping member relative to said looper and on the same side of said looper as said needle, said clamping member being resilient and having a retaining portion thereof disposed in close juxtaposition with a yarn-carrying portion of said looper bill for clamping one leg of a cut loop between the retaining portion of said clamping member and said looper bill.
