Abstract
Abstract A cushioned panel is provided together with a process of molding it. A non-woven fabric having an outer layer composed of polypropylene or other thermoplastic fibers is heated to the melting point of the fibers. It is inserted into a mold having a decorative surface fabric and a piece of foam cushioning therein. The mold is designed so that the edges of the male and female mold halves compress the molten non-woven substrate and the surface fabric forcing the molten surface of the substrate into the interstices of the surface fabric. A mechanical bond is formed upon cooling.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
150 words
A decorative laminate panel, which comprises; a first, non-woven fabric of thermoplastic fibers having at least one surface formed by the melting under pressure and re-solidification by by cooling of said fibers on the surface of said first fabric; a second fabric having an edge portion bonded to an edge portion of said surface of said first fabric through said melting and re-solidification of the fibers, said surface of said first fabric at least partially penetrating within said second fabric, creating a mechanical bond therewith, said second fabric including an outer decorative surface, said decorative surface defining first, second and third sides of said panel, and asurface of said second fabric defining a fourth side of said panel opposite to said first side, said second and third sides joining said first and fourth sides, respectively; and a layer of foam positioned between and contacting with said first and second fabrics.
Claim 2
Dependent Claim
150 words
A decorative laminate panel, which comprises; a first, non-woven fabric of thermoplastic fibers having at least one surface formed by the melting under pressure and re-solidification by by cooling of said fibers on the surface of said first fabric; a second fabric having an edge portion bonded to an edge portion of said surface of said first fabric through said melting and re-solidification of the fibers, said surface of said first fabric at least partially penetrating within said second fabric, creating a mechanical bond therewith, said second fabric including an outer decorative surface, said decorative surface defining first, second and third sides of said panel, and asurface of said second fabric defining a fourth side of said panel opposite to said first side, said second and third sides joining said first and fourth sides, respectively; and a layer of foam positioned between and contacting with said first and second fabrics.
Claim 3
Dependent Claim
94 words
A panel as described in claim 1 having in cross section a body portion and two symmetrical projecting portions forming a generally U-shaped configuration, said foam piece being positioned between said fabrics for the length of said body portion, said fabrics being bonded to each other near the outermost portions of said projecting portions, said first fabric having a progressively decreasing thickness in the direction of the outermost portions of said projecting portions, said foam piece having opposing edge portions extending partially within said projecting portions between said fabrics, said edge portions being compressed.
