ABSTRACT:
A method and device for releasing defectively inserted weft threads in weaving machines by reversing the machine to expose the defectively inserted thread in the open shed, initially releasing the weft thread from the ends of the fell by moving the weft thread away from the fell at its ends, positioning releasing elements between the released portion of the weft thread and the fabric fell, releasing an additional portion of the weft thread from the fell by moving the releasing elements away from the fabric fell toward the machine reed, positioning an additional releasing element between the seft thread and the fabric fell, releasing an additional portion of weft thread from the fell by moving the additional releasing element away from the fell and toward the reed, and containing the positioning of the releasing elements across the shed of the weaving machine until the weft thread is released over the entire length of the shed.
