ABSTRACT:
A continuous rotary method for surface shaping of resilient material such as synthetic foam. Three dimensional surface geometries of well defined and arbitrary shapes are obtained by pressing foam against a die roller to compress some foam portions to a reduced thickness against raised portions of the die and extrude other foam portions into depressions of the die, and cutting away the extruded portions. The compressed portions return to an uncompressed state after passage against the die roller and form raised areas on the foam surface around depressions corresponding to the cut away portions of foam.
