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;interposing in the gap between the compression roller and the support surface a moving continuous patterned flexible belt defining at least one recess;continuously 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 flexible belt 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 the support surface; andtransversely 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 flexible belt.
