ABSTRACT:
A process for manufacturing stratified pieces, such as roof tiles and wall tiles, by sucessive and independent extrusion of mortars or concretes. In the process mortar is deposited on a limited part of the molds. The mortar is extruded and compacted, and some mortar is dislodged from cross strips in each zone of contact between two consecutive molds. Thereafter, complete sheets of mortar are shaped on the first layers, filling both the emptied cross strips and the limited sides, and lastly the thicknesses of the pieces are cut in their entirety in a vertical transversal plane at each zone of contact of the molds to form multiple layer tiles having homogeneous facing surfaces.
