ABSTRACT:
A method and apparatus for automatically unravelling a fringe area in a fabric is provided. The apparatus uses a reciprocating, hooked needle and a reciprocating blade to pull weft threads from the plane of a fabric and cut them off. The needle and hook are advanced in the direction of the warp threads, unravelling the weft threads until a fringe area of a certain width has been formed. The apparatus is then displaced along the edge of the fabric and the unravelling cycle is repeated. The apparatus continues to be moved along the edge of the fabric until the fringe area extends the length of the edge.
