According to the present invention, a roll mold comprises a first forming assembly formed by being inserted into and attached to a first shaft by alternating a plurality of first forming rolls and a plurality of second forming rolls. Moreover, the roll mold has tooth having different forms or gear tooth wherein the first forming roll and the second forming roll are in contact with each other are crossed and engaged with each other. The present invention has the advantage of easily manufacturing an anisotropic corrugated panel which is easily bent, having excellent smoothness, and having low orientation of bending strength at low costs by combining a typical gear shape in various forms. |
