ABSTRACT:
A method is provided for making a hermaphrodite hook and loop fastener including the steps of molding a hook ribbon having mounting projections and shoulders on opposite sides of the hook ribbon, providing a separate flexible substrate, feeding a plurality of hook ribbons to a bonding station, orienting the hook ribbons with their hooks upstanding from the substrate and their mounting projections facing the substrate at the bonding station, pushing the shoulders of the hook ribbon toward the substrate thereby thrusting the mounting projections onto the substrate, and ultrasonically bonding the mounting projections to the substrate.
