Document Type and Number:
Japanese Patent JP3219292
Kind Code:
B2
Abstract:
Novel method and apparatus for forming a substrate or honeycomb article with multi-cellular densities and/or multi-cellular geometries by positioning a pair of extrusion dies adjacent one another, such that one surrounds the other, and such that discharge slots of one die produce different cellular densities and/or geometries from that of the other. Further, an annular batch reservoir is formed between the mating surfaces of such dies so as to facilitate the flow of batch material from one die to the other, and an integral inner skin is formed between the differing cellular structures.
