ABSTRACT:
The invention relates to apparatus for producing ceramic tiles with ornamental shapes from clay emerging from an extrusion press. Shaped punching tools are disposed on either side of the clay column from which the tiles are to be formed, and are moved on a carriage in the direction of the moving column at a speed corresponding to the speed of the moving column. Supports hold the clay while it is being punched. A drive system such as a fluid actuated drive system moves the punching tools, and the drive system is selectively actuated in response to movement of the carriage. Cutting wires sever each column section acted upon by the punching tools from the rest of the column.
