摘要:
The invention relates to a method of producing a tablet, especially a detergent tablet, which consists of at least one first and one second layer. The inventive 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 said first metered quantity with a first mold pressure by means of a molding plug that has at least one convexity on its pressing surface, to produce a first compacted layer that has one or more respective indentation(s) in its upper surface that correspond(s) to the convexity/convexities on the molding plug; 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 said second metered quantity with a second mold pressure by means of a molding plug, to produce a second compacted layer with one or more respective indentation(s) in its upper surface. The invention also relates to the products obtained by said method.
