Abstract:
A method for shaping a cellular polymer material by cutting a portion from a surface of the material, comprising:establishing a predetermined gap between a compression roller and a cooperating support surface; feeding a slab of the cellular polymer material through the gap between the compression roller and the cooperating support surface and compressing the slab while a surface of the slab is adjacent to the moving continuous patterned platform so that the at least one recess is substantially filled by a portion of the cellular polymer material when the slab is compressed as it is passed through the gap between the compression roller and support surface; and transversely cutting from the slab with a blade as the slab emerges from the gap between the compression roller and support surface at least a fraction of the portion of the cellular material received within the recess of the patterned platform.
