ABSTRACT:
A conveyor belt carries a plurality of cut pieces of fabric in succession to an edge trimmer which successively cuts a trim edge on each cut piece along a predetermined straight line. A band of trim of double thickness is placed in tension and sewed to the cut pieces to overlap the trim edges thereof. The trim edges are closely spaced together to reduce trim waste. A forwardmost cut piece is separated from the next following cut piece so as to increase blade clearance between them. The resulting blade clearance is large enough to permit the forwardmost cut piece to be severed from the next following cut piece by a blade which cuts that intermediate band section which joins the two. The served cut piece is then picked up and dropped to fall flat on top of a stack.
