Abstract
Disclosed is a novel extrusion die mask for use in the extrusion of honeycomb structures. The mask includes a stationary portion with an orifice extending longitudinally therethrough. A movable recess means is provided which forms a recess communicating between the outlet face of an extrusion die and the central orifice which receives and compacts extruded batch material from the die to form the skin of the extruded honeycomb structure. An adjustment means is provided for controlling the depth of the recess whereby the amount of material directed to the skin of the structure may be varied as batch viscosity varies and as product requirements indicate.
