Abstract
In a method of manufacturing objects, extrudable ceramic forming material is extruded through multiple dies arrayed around an extrusion axis, the dies mounted to permit controlled movement of the dies during the course of extrusion to vary the position of several extrudate streams exiting the dies. Extruded objects are defined by spokes corresponding to the extrudate streams with the streams having a varying spacing from a central axis.
Claims19
A method of manufacturing objects comprising extruding extrudable material through a plurality of dies, the dies arrayed around an extrusion axis, the dies mounted to permit controlled movement of the dies during the course of extruding the extrudable material to vary the position of extrudate streams exiting the dies relative to the axis.
A method as claimed in 6, wherein the relative movement is in a direction parallel to the axis of extrusion.
