  • Surface fastener molding apparatus and its operational method, and a method for producing a surface fastener
    Patent number: 10723046
    Abstract: A surface fastener molding apparatus includes a supporting structure and a second supporting structure for axially supporting a mold roll in a rotatable manner at a first end side and a second end side of the mold roll which is opposite to the first end side. The mold roll includes a circumferential surface in which a plurality of mold cavities for molding engaging elements of the surface fastener is provided. A first linear driving means and second linear driving means are provided which are for, respectively, advancing or retracting the first supporting structure and the second supporting structure. The degree of closeness between the extruding nozzle and the mold roll is regulatable across the first end side and the second end side of the mold roll, based on at least one activation of the first driving means and the second driving means.
