Conventionally, composite plates and their manufacturing methods similar to the present invention have been disclosed, for example, in Japanese Patent Publication No. 15693/1983 (Corrugated board with porous synthetic resin filled in the recesses), as a method of filling the recesses of a textured sheet with foamed resin. Paper manufacturing method and apparatus) involves applying a foamable synthetic resin dissolved in a solvent or mixed with glue to a flat piece of paper or the entire surface of the paper, and pressing it onto each corrugated crest of corrugated paper to fit into the recesses of the corrugated paper. Cover the lid and heat it under pressure to prevent the synthetic resin in the crest of the wave from foaming, but to foam only the synthetic resin in the recessed area.
A method for filling the entire recess with this is disclosed.

であつた。Example In FIG. 1, a sheet 2 (high-density polyethylene, density 0.958, MI 1.0, thickness 5 mm), which has just been molded into irregularities and is still in a softened state, is conveyed by a belt conveyor 4 at a constant speed of 5 m/min. An appropriate amount of commercially available expandable polystyrene beads 1 was filled into the concave portions of the uneven sheet 2 from a hopper 5, and the thickness was leveled with a knife 6 to a constant thickness, followed by a heating belt conveyor with a length of 7.5 m and heated to a temperature of 115°C. The expandable polystyrene beads were foamed by pressing and heating at step 8. At this time, liners 3 and 3' made of high-density polyethylene (same material as the sheet 2 above) are introduced in a molten state onto both sides of the sheet 2 while heating with heating heaters (15 x 1.5KW heaters) and fused together. After that, it was cooled by a cooling belt 9 to obtain a composite plate with independent air chambers as shown in FIG. The adhesion between the core, liner, and filler of this composite plate was very strong.
