A method for the manufacture of roof tiles involves the introduction of tile material into a hopper 1 for subsequent depositing on a series of moving pallets 8, for forming a basic strip 11, which is cut into individual tiles 12. One or more pigments colouring the mass is added to the material before it is introduced into the hopper 1, for example in a screw conveyor 2, which runs to the hopper, and one or more secondary colour pigments are added to the material in the hopper 1 in order to obtain tiles with striped surfaces. <IMAGE> |
