Abstract:
An apparatus for shaping a slab of cellular polymer material by cutting and removing portions of the material from an outer surface of the slab, comprising:a compression roller and a drive roller, said compression roller rotatable on an axis and having its outer surface spaced apart from the drive roller to define a predetermined gap therebetween so that the compression roller exerts a compressive force against the slab of cellular polymer material as said slab is passed through said gap between the compression roller and the drive roller; a continuous patterned platform driven by the drive roller, said patterned platform having an outer surface and being interposed in the gap between the compression roller and the drive roller and moveable with relation thereto, said outer surface of said patterned platform defining at least one recess to receive a portion of the cellular polymer material when a region of the slab is passed through said gap and compressed between the compression roller and the drive roller, wherein the at least one recess has a predetermined depth, and a blade for cutting the cellular polymer material as the slab emerges from the gap between the compression roller and the drive roller; said blade positioned adjacent to the gap and to the outer surface of the patterned platform to cut a portion of the cellular material received within the recess of the patterned platform.
