摘要:
A method is provided for producing a tablet, especially a detergent tablet, which includes at least one first and one second layer. The method comprises the following steps: (a) introducing a first metered quantity of a first particulate composition into a molding cavity of a tablet press; (b) compacting the first metered quantity with a first mold pressure by means of a molding punch that has at least one convexity on its pressing surface, to produce a first compacted layer that has one or more respective indentations in its upper surface that corresponds to a convexity/convexities on the molding punch; (c) introducing a second metered quantity of a second particulate composition into the molding cavity of the tablet press on top of the first compacted layer; and (d) compacting the second metered quantity with a second mold pressure by means of a molding punch, to produce a second compacted layer with one or more respective indentations in its upper surface.
