Abstract
A honeycomb extrusion apparatus includes first and second vanes with respective first and second face portions. First and second axial widths of a circumferential feed area are respectively defined between the first and second face portions and the outer feed surface of the die body. In further examples, methods include the steps of selectively adjusting the first axial width and the second axial width of the circumferential feed area by respectively adjusting the first and second vane relative to the mask. In further examples, a honeycomb extrusion apparatus includes a plurality of mask segments that each includes an inner peripheral surface portion. Each of the plurality of mask segments are independently adjustable along a respective radial axis.
