A curl bow machine manufactures curl bows in accordance with a curl bow manufacturing process. Ribbon is controllably unwound from spools and prepared for stretching by a curling rod. The curling rod applies controlled tension onto the ribbon, thereby curling it. Several strands of ribbon may be curled simultaneously, with the ensuing curled ribbon stream passed on to a wire stitcher. In a specific embodiment, a wire stitcher takes hang tags from a hang tag delivery and cutting system so that individual hang tags may be attached as by staples to the curled ribbon stream. The wire stitcher forms and attaches such staples to the ribbon and hang tag. In other instances, a backing material or wire tie is used in lieu of a hang tag. In a preferred embodiment, a venturi suction and discharge system then delivers the curled ribbon stream with its attached hang tags to a cutter so that individual curl bows may be separated from the ribbon stream. The individual curl bows are then discharged from the venturi system and may be gathered in a box or similar container for packaging and delivery to the customer. A second nip roller may also be used in place of the venturi suction and discharge system.
