Abstract

PURPOSE: In the production of inorganic hardboards which are composed of calcium-aliminate-trisulfate hydrate and a reinforcing material, boards are pressed stepwise with a plurality of paired rolls whose intervals lessen in order, thus preventing the occurrence of unevenness on the surface of the base.
