Abstract

Apparatus and method for making moulded products that includes a containment body for a predefined quantity of loose material such as powdery, fibrous or granular material. The body has at least one expelling opening for expelling the loose material. The molded products also include a forming chamber having a bottom wall and an access opening configured to be in communication with the expelling opening to allow the passage of the material from the containment body above the bottom wall; and a compacting unit operatively engaged in the forming chamber to compact the loose material and to define a dose in a single body.
