Abstract
Apparatus and a method for extruding a honeycomb, providing correction in bowing of the extruded honeycomb structure, employs a deflector device having a base plate including an aperture aligned in a direction parallel to the extrusion axis through which the plastic material is conveyed to the die, the aperture having a varying diameter; and, a slide plate movably mounted to the base plate, the deflector device positioned upstream of the extrusion die, the degree of bow reduction depending on the diameter or width of the aperture imparting a pressure drop gradient on the flow stream entering the die.
