PROBLEM TO BE SOLVED: To integrally form a plane fastener having flexibility and less occurring crack on the substrate backed with a backing material made of knitted fabric, cloth, non-woven fabric, paper, synthetic resin sheet or the like. SOLUTION: A sheet shaped molten resin 4' discharged from an extruding nozzle 1 is introduced to the periphery of a die wheel 2 having a number of cavities 5 for fitting pieces on the periphery and a cooling means built therein and the molten resin 4' is filled in the cavity 5 for fitting piece and the die wheel 2 is driven revolutionary to the extruding direction of the molten resin 4' to form a number of fitting pieces 4b integrated with the surface of a plane substrate 4a. Separately, a backing member 3 is supplied through a guiding path 1b for the backing member, the backing member 3 is partly pressed on the back side of the plane substrate (4a) using a pressing roll (5) with the revolution of the die wheel 2 to form integrately with the substrate 4a and cooled on the periphery of the die wheel 2 and a formed plane faster integrated with the backing member 3 is forcedly released from the die wheel 2. |
