First and second molten resins (4a, 4b) are continuously injected toward the respective circumferential surfaces of a die wheel (2) and an associated roller (7) in rotation in opposite directions. The die wheel (2) has in its circumferential surface a multiplicity of engaging-element-forming cavities (5), and the associated roller (7) is disposed in parallel confronting relationship with the die wheel (2) with a gap equal to the thickness of a substrate sheet (40a) of a molded surface fastener member (40). During that time, a porous core sheet (8) is introduced toward a meeting point of the first and second molten resins (4a, 4b) and is sandwiched between a first substrate sheet part (4a''), which is molded on the circumferential surface of the die wheel (2), and a second substrate sheet part (3), which is molded on the circumferential surface of the associated roller (7), to form a unitary laminate substrate sheet (40a). The resulting molded surface fastener member (40) is free from expansion and local thin portions in either substrate sheet part (4a'', 3) and is therefore prevented from being torn. <IMAGE> |
