MOLDING METHOD OF MOLDED SURFACE FASTNER MOLDED SURFACE FASTNER MANUFACTURED BY THE METHOD AND MOLDING APPARATUS THEREOF

摘要

The molten resin material is continuously extruded from the first extrusion hole 102 extending in the width direction of the first extrusion nozzle 101, so that the second extrusion hole 109 is positioned at a position corresponding to the first extrusion nozzle 102. It passes through the second extrusion nozzle 103 is disposed in front of the first extrusion nozzle (101). The second extrusion hole 109 is a single extrusion hole having a plurality of longitudinal rectangular openings 109b with equal pitches in the width direction, and the first extrusion hole 102 corresponds to a base corresponding to the connecting portion 109c. It is a single extrusion hole having a member molding opening 102c and a connecting element molding opening 102a disposed to correspond to the rectangular opening 109b. The first extrusion nozzle 101 and the second extrusion nozzle 103 are relatively oscillated, and the surface fasteners are formed on the surface of the sheet-shaped base member 11 so as to intersect the extrusion holes 102 and 109 positioned facing each other. The connecting elements 12 each having a connecting head portion protruding back and forth in the forming direction from one end of the stem portion standing up to each other are continuously formed during molding. At this time, each connecting element 12 has a shape similar to the parallelogram of the plane.
