ABSTRACT:
For the production of screw fasteners with plastic patches thereon, the fasteners are preheated to a high temperature. Each heated fastener pauses at a processing station where a predetermined increment of a plastic strip is severed and dropped onto the hot fastener and as the plastic melts a pressure shoe forms the plastic to the curved cross-sectional configuration of the fastener. The fasteners are then quenched. For high production a number of the fasteners are processed simultaneously on each of the repeated cycles of operation. The apparatus is readily adjustable to handle fasteners of different sizes.
