Abstract: The present invention relates to bedding product having heat-dissipation and support properties provided by structural protrusions on the surface of the bedding product. The bedding product may comprise a first layer of foam, that includes a base support having an upper surface and a lower surface and a plurality of open and closed protrusions located on the upper surface of the base support. Each open protrusion comprises a cavity formed therein, wherein the cavity has a depth of at least 0.

Abstract: A thermal and acoustic barrier for automotive floor pan carpeting is made by cutting synthetic foam sheet in a continuous process to create a foam surface complementary to the three dimensional shape of the floor pan surface. The cut foam sheet is bonded to the underside of the carpeting and installed with the complementary foam surface facing the floor pan.

Abstract: Synthetic foam compressed between a pattern roller and a smooth compression roller is driven against a cutting edge closely adjacent and tangent to the pattern surface but spaced from the compression roller to reproduce a three dimensional pattern roller surface on the foam sheet. Three dimensional patterns of arbitrary geometries including sharp edged, flat surfaced geometric solids can be reproduced on a foam surface.

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.
