PROBLEM TO BE SOLVED: To reduce the usage amount of a resin sheet and improve the surface property of a laminated molded article by a method wherein the tip part of a parison and the tip part of a resin sheet are pinched just after the ejection of the parison so as to hang down the resin sheet by a predetermined length in synchronism with the parison and pinch the parison and the resin sheet between the mold in order to blow the air in the parison. SOLUTION: Both the lower end parts of a parison P and of a resin sheet S are brought to nearly the same position by pivoting feed rolls 20a and 20b so as to feed the tip part of the resin sheet S along a guide plate 18 simultaneously with the ejection of the parison P. Next, by bringing a pinching device 16 near to the parison and the resin sheet so as to simultaneously pinch both the lower parts of the parison P and of the resin sheet S and then the pinching device 16 is released. In succession, a molten resin is pressingly fed from an ejecting device in a die head 19. Next, after the resin sheet S hangs together synchronously with the parison P clown to a predetermined position. As the parison P and the resin sheet S are interposed between both the molds 7, the molds are closed and pinch them. After that, pressure air is blown through blow pins in the parison P. |
