Abstract

PURPOSE:To prevent the void formation due to the air involvement in a heat insulation board by a method wherein a urethane resin is poured to a substrate material to spread said resin throughout the substrate material so as to make a central part thereof thick and, thereafter, said resin is foamed and molded by a double conveyor. CONSTITUTION:A substrate material 1 having a thin shallow bottom made of a polyvinyl chloride resin is placed on a lower conveyor 7 and a urethane resin 2 is poured into the substrate material 1 from a pouring machine 10 while strirred therein by a motor and, thereafter, foamed and molded between an upper conveyor 6 and the lower conveyor 7. The urethane resin 2 poured into the substrate material is spread under pressure through a backing sheet 13 prior to foaming and spread under pressure over a total surface of a bottom surface 1a of the substrate material 1 as well as a central part of the urethane resin 2 is made thick. Subsequently, the urethane resin 2 initiating the foaming is conditioned by a shaping roller 12 and an upper surface of the resin 12 is made flat by the upper and the lower conveyors 6, 7.
