  • Extrusion dies for thin wall substrates
    Patent number: 4468365
    Abstract: Method and apparatus is set forth for extruding honeycomb structures having cohesive cellular walls from an extrusion die. Deflector means are provided within flow passageways of the die, wherein the deflector means has a secondary feed system such that the batch flow from the main feed system is broken up into a multi-channel stream system which improves the flow of the batch material into the discharge slots, thus improving product quality and knitting or cohesiveness of the material prior to discharge from the die.
