PROBLEM TO BE SOLVED: To obtain a good-looking laminating blow-molded article by quickly cutting off burrs and an excess nonwoven fabric. SOLUTION: A pair of blow molding molds 1 and 2, a slide mold 3 comprising a plurality of slide cores 3a arranged on the opening part side of the blow molding mold 1, a nonwoven fabric arrangement means 5 for arranging a nonwoven fabric F on the front of the slide mold 3, and a parison molding means for extruding a parison P between the nonwoven fabric F and the blow molding mold 2 are provided. The slide mold 3 constitutes a mold splitting surface between it and the blow molding mold 2. When the slide cores 3a of the slide mold 3 advance to constitute a molding cavity with the blow molding mold 1, a ring-shaped undercut part 8 is formed in the cavity. Since a parting line hides on the back side (the nonwoven fabric is stuck on the surface side), appearance is not affected by burrs left here. |
