ABSTRACT:
An extrusion die is used for producing ceramic honeycomb materials. It is particularly useful in producing such extrudates in sheet form by configuring the die in the form of a cylinder and providing a cutting device proximate to the exterior of the cylinder so that when relative rotation is imparted between the cutter and the cylinder, a honeycomb sheet is removed. A cover can be provided over the exterior surface of the cylindrically-shaped die to permit formation of honeycomb extrudates in pellet form.
