Method and apparatus for manufacturing surface fastener

Image Number 4 for United States Patent #5512234.

Molten resin is extruded in a predetermined width from an extrusion nozzle. The molten resin is forced to a die wheel, which is situated facing the extrusion nozzle with a predetermined gap therewith, has inside a cooling unit and is adapted to be rotated in one direction. On the surface of the die wheel, a flat-plate-like substrate member and engaging members are integrally molded of the molten resin. Simultaneously, as a continuous filament is supplied, loop members are successively formed. Then the loop members are pressed against the substrate member in upright posture and are successively fused therewith.
