PROCESS FOR PRODUCING CORRUGATED PLATE AND CORRUGATED PLATE

摘要

Provided is a process for corrugated-plate production in which the shape of the corrugation to be formed on a surface can be controlled. Also provided is a corrugated plate obtained by the process. The process for producing a corrugated plate (1a) comprises: a step in which unhardened clay (5) having irregularities embossed therein on the upper side is superposed on the upper side of a rubber sheet (4) in a stretched state; a step in which the rubber sheet (4) is allowed to shrink to thereby form corrugation (2) on at least the surface of the clay (5); and a step in which the clay (5) is fired to harden the clay (5).
