| description | A device and method for correcting extrudate bowing in any direction to true "zero" magnitude. The bow deflector device includes a base having an aperture sufficiently large for a feed stream of plastic batch material to pass therethrough, and a plurality of adjustable plates movably mounted to the base, each adjustable plate being capable of independent movement, wherein by passing through the bow deflector device a unique flow velocity is superimposed on the feed stream of plastic batch material, as determined by the diameter of the aperture, and the position of the adjustable plates. The bow deflector device optionally includes a cover for the adjustable plates, securely mounted to the base. In an apparatus for extruding a honeycomb structure, the bow deflector device is positioned upstream a honeycomb die, such that a feed stream of plastic batch material passes through the bow deflector device prior to entering the die. |
