ABSTRACT:
An apparatus for manufacturing tiles by extrusion of clay or a similar material comprising a die adapted with a number of spaced apart pivotable rigid blades which are arranged such as to equalize the output speeds of several superposed layers of extruded material. Means are also provided substantially in the planes of the blades downstream of the outer ends thereof for projecting a pulverized powder product at right angles to the direction of extrusion into interstices between the layers. Impermeable coatings are added to the outer surfaces of the superposed layers and the assembly is then cut into piles of tiles which can then be delivered into an oven for baking, the heat ensuring removal of the impermeable coating and the separation powder product.
