Abstract

PURPOSE: To obtain a product which prevents the generated gas from stagnating, excellent in flatness and strength by a method wherein fine holes are arranged by the belt of an upper conveyor with main-shaped projections implanted on the whole surface of the rear surface paper while an expandable synthetic resin is foamed.
CONSTITUTION: The upper surface of a face plate 12 which is carried on a lower conveyor 1 is filled with expandable synthetic resin 2, the rear surface paper 3 is supplied onto the expandable synthetic resin 2 so that the upper surface of the paper is coated, the rear surface paper 3 is pressed on the expandable synthetic resin 2 on the face plate 12 between the upper conveyor 4 arranged facing the lower conveyor 1 and the lower conveyor 1 and a plurality of fine holes 7 are provided on the rear surface paper 3 by a plurality of nail-shaped projections 6 implanted over the whole surface of the belt 5 of the upper conveyor 4. The gas produced in an expanding time is exhausted through the fine holes 7 and is not reserved between the rear surface paper 3 and the expandable synthetic resin 2.
