Abstract (en)
[origin: WO8500135A1] A process for manufacturing roof tiles includes introducing tile forming material into a hopper (1) for subsequent discharge onto a succession of moving pallets (8) to form a base ribbon (11) which is cut into individual tiles (12). One or more body colouring pigments are added to the material prior to its introduction into the hopper (1), for example in a screw conveyer (2) leading to te hopper, and a secondary colouring pigment or pigments is added to the material in the hopper (1) to provide the tiles with streaked surfaces.
