Zusammenfassung:A molding apparatus for a patterned shaped article includes a retainer having a plurality of retaining portions for retaining particles, a supply tank means for charging particles into the retainer, a remover for removing the particles from some of the retaining portions of the retainer, and another supply tank for charging particles of a different kind into the retaining portions from which the particles were removed. The apparatus produces a patterned shaped article by conducting at least one cycle of operation in which particles are charged into the retainer, the charged particles are removed from some of the retaining portions of the retainer and particles of a different kind are charged into the retaining portions from which the particles were removed, and releasing the particles retained by the retainer to form a course of prescribed thickness on a base surface.
