PURPOSE:To reduce inspecting time and labor, by providing a sheet of intermediate paper, whose surface has affinity with the back surface of a plate shaped body, between the plate shaped bodies, preventing the remaining of the intermediate paper on the surface of the plate shaped body to be inspected at the next time, and avoiding the extra operation for deviating the intermediate paper. CONSTITUTION:Plate shaped materials 1 are stacked and a laminated body 2 is formed. A sheet of a plate shaped material 1A is lifted or deviated at the upper part of the laminated body 2. The quality of a surface 1B' of a plate shaped material 1B, which appears at this time, is inspected by the naked eyes. In this case, an intermediate paper 3, whose surface has affinity with the back surface of the plate shaped material, is provided between the plate shaped materials at the stage of forming the laminated body 2 in advance. The affinity is utilized only during the time the plate shaped material is moved. For example, a smooth surface, which is obtained by coating ordinary paper with a synthetic resin, is used. The paper is not specified. For example, high quality paper or pulp paper can be used. As a synthetic resin, low density polyethylene is used. |
