PURPOSE:To enable continuous molding of a composite board or sandwich board in an arbitrary shape within a predetermined period of time, by a method wherein a process up to a time when blowing pressure becomes maximum is formed by a caterpillar type mechanism and a sphere wherein conveyance and cure are performed after that is formed by a roller mold. CONSTITUTION:A cure oven 4 is constituted with a caterpillar type mechanism 5, a roller mold 24, heaters 33-35 and a cover 24, as for the inside of the caterpillar type mechanism 5, foaming material 2 is placed between a base material 3 and backing material, the base material 3 and the backing material are bonded each other through reaction and foaming of the foaming material 2 and molded, and a composite belt is fed to the roller mold by making blowing pressure into a state wherein the same begins to lower gradually from the maximum pressure. The roller mold 24 is arranged directly after an outlet of the catapillar type mechanism 5 like an extended straight line of a mold 18, a board S obtained by sandwiching the foaming material 2 is conveyed, a foaming system of the foaming material 2 is cured and sent out through the outlet. The heaters 33-35 heat the caterpillar type mechanism 5 and roller mold 24, accelerete reaction and foaming of the foaming material 2, perform necessary cure and homogenize reaction series and the foaming system of the foaming material 2.
