ABSTRACT:
In manufacturing a continuous surface fastener tape on an injection molding machine, a male engaging portion is injection molded on one surface of a continuous substrate sheet of thermoplastic resin at one longitudinal margin, and an adhesive agent is applied to the other surface of the substrate sheet at the other longitudinal margin to form an adhesive layer. The surface fastener tape is stored in superposed form, such as in roll or in stack, and can be out into individual surface fastener pieces for use as it is demanded. In production, molten resin is continuously injected to the die wheel from an injection nozzle to mold the continuous surface fastener tape, and the adhesive layer is formed on the surface fastener tape using an adhesive-agent applicator.
