Abstract
An apparatus for shaping a slab of compressible or cellular polymer material ( ), such as polyurethane foam, shapes such slab by cutting portions of the material from one surface. A moving patterned platform ( ), preferably an endless belt or a series of interconnected panels, is interposed between a compression roller ( ) and a cooperating surface ( ) and defines at least one recess ( ) or at least one projection ( ) or a combination of recesses and projections. When the slab is compressed between the compression roller and the platform, which is supported by the cooperating surface, a portion of the material fills the recess or recesses in the moving platform. At least a portion of the compressed material within the recess(es) is then cut from the surface of the slab by a blade ( ) just as the slab emerges from between the compression roller and the platform, leaving a profile-cut surface with cut-out portion(s) corresponding in pattern and shape to the recess(es) provided in the moving patterned platform. Alternatively, a portion of the material is forced away form the blade ( ) by the projection or projections ( ) so that a portion of compressed material is not cut by the blade ( ).
