Filed: 2007-05-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a roof tile manufacturing method which can extremely inhibit the frequency of a defective product caused by deformation, even in case a tile material is deformed by drying.  <P>SOLUTION: First, a tile material is molded by pressing a clay material, and then an additional build-up of the wall thickness is performed in accordance with the shrinkage level of a molding region, considering the level of the overall shrinkage of the molded tile material 55 occurring as a result of its undergoing a drying process. That is, the molding region whose shrinkage factor is high, is molded by projecting (building up) the wall thickness relatively larger than the molding region with a normal shrinkage factor so as to allow approximation of the former molding region to a targeted external shape after shrinkage. The molding region with a low shrinkage factor is molded in the way it does not project relatively significantly. Under this constitution, it is possible to approximate the tile material 55 to the external shape, of the molding region, whose shrinkage by drying is an essential objective criterion, in case the tile blank 55 shrinks by drying.  <P>COPYRIGHT: (C)2009,JPO&INPIT
