<p>PURPOSE: To form an article in a simple and relatively inexpensive manner in an apparatus for forming the article with multi-cellular densities and/or multi-cellular geometries. CONSTITUTION: An extrusion die 12 having discharge slots 36 with a cellular density and geometry is surrounded with an extrusion die 14 having discharge slots 38 with different cellular density and/or geometry. An annular batch reservoir 50 is formed on matting surfaces 52, 54 adjacent one another.</p> |
