ABSTRACT:
Apparatus and a method for extruding a honeycomb, providing reductions in curvature or bowing of the extruded honeycomb structure, employs a bow deflector positioned upstream of the extrusion die, the bow deflector comprising adjoining, independently rotatable, first and second aperture plates of tapering thickness, the degree of bow reduction depending on the relative rotational position of the aperture plates and the resulting magnitude of the pressure/flow velocity gradient imparted by the plates on the flow stream entering the die.
