Abstract
Abstract A laminated article of manufacture, especially suitable as a decorative surface covering, and a method of making the same are disclosed herein. This method contemplates laminating together a layer of paper back supported aluminum foil, a layer of transparent and heat shrinkable material and a top layer of at least partially transparent material which displays a given design. The layers are consolidated into a unitary structure under pressure and heat for a given period of time so as to cause irreversible shrinkage of the heat shrinkable material and the production of randomly located creases in the layer of metallic foil. The ultimately produced article sets forth a unique design and aesthetically pleasing appearance.

Claim 1
Independent Claim
142 words
A METHOD OF MAKING A DECORATIVE LAMINATED ARTICLE OF MANUFACTURE, COMPRISING: A. POSITIONING A PLURALITY OF LAYERS OF MATERIAL IN STACKED RELATIONSHIP TO ONE ANOTHER WITH ADHESIVE MATERIAL BETWEEN ADJACENT LAYERS, SAID LAYERS INCLUDING I. AN ARTICLE SUPPORT LAYER, II. A LAYER OF LIGHT-OPAQUE, CREASABLE MATERIAL POSITIONED OVER SAID ARTICLE SUPPORT LAYER, SAID MATERIAL INCLUDING A LIGHT-REFLECTIVE SURFACE FACING AWAY FROM SAID SUPPORT LAYER, III. A LAYER OF AT LEAST PARTIALLY TRANSPARENT AND HEATSHRINKABLE PLASTIC MATERIAL DISPOSED ON THE REFLECTIVE SURFACE OF SAID LIGHT-OPAQUE LAYER, AND IV. A LAYER OF AT LEAST PARTIALLY TRANSPARENT PLASTIC MATERIAL DISPOSED ON SAID HEAT-SHRINKABLE LAYER, AND B. COMPRESSING AND SUBSTANTIALLY SIMULTANEOUSLY HEATING SAID POSITIONED LAYERS SO AS TO CAUSE I. SAID LAYERS TO BOND TOGETHER, II. SAID HEAT-SHRINKABLE MATERIAL TO SHRINK, AND III. THE PRODUCTION OF A PLURALITY OF RANDOMLY LOCATED CREASES IN SAID OPAQUE LAYER.

Claim 3
Dependent Claim
43 words
A method according to claim 1 wherein the adhesive material between said layers of creasable material and heat-shrinkable material is a heat-shrinkable plastic adhesive, said shrinkable adhesive shrinking along with said heat shrinkable material due to said compressing and heating of said layers.
Claim 4
Dependent Claim
35 words
A method according to claim 1 wherein said compressing and heating step includes applying between approximately 800 psi and 1400 psi pressure to said positioned layers at a temperature of between approximately 260*F and 300*F.
Claim 5
Dependent Claim
25 words
A method according to claim 3 wherein said pressure is applied to said layers at said temperature for between approximately 16 minutes and 22 minutes.
Claim 6
Dependent Claim
18 words
A method according to claim 1 wherein said layer of transparent plastic material displays a visible predetermined design.
Claim 7
Dependent Claim
25 words
A method according to claim 5 wherein said last-mentioned layer is comprised of a birefringent material, whereby it is adapted to scatter light impinging thereon.
Claim 8
Dependent Claim
19 words
A method according to claim 1 wherein said layer of opaque material is a malleable and ductile metallic foil.
Claim 9
Independent Claim
170 words
A method of making a laminated article of manufacture, comprising: a. positioning a plurality of layers of material in stacked relationship to one another with adhesive material between adjacent layers, said layers including i. a lowermost article support layer, ii. a layer of metallic foil bonded on one side of a support backing, said foil and backing being disposed on top of said article support layer with the backing located therebetween, iii. a layer of at least partially transparent and heat shrinkable plastic material disposed on said layer of foil, and iv. a layer of at least partially transparent plastic material disposed on said heat shrinkable layer; and b. compressing said positioned layers with a pressure of between approximately 800 psi and 1,400 psi at a temperature of between approximately 260*F and 300*F for between approximately 16 to 22 minutes, thereby causing i. said layers to bond together, ii. said heat shrinkable material to shrink, and iii. the production of a plurality of randomly located creases in said metallic foil.
Claim 10
Independent Claim
170 words
A method of making a laminated article of manufacture, comprising: a. positioning a plurality of layers of material in stacked relationship to one another with adhesive material between adjacent layers, said layers including i. a lowermost article support layer, ii. a layer of metallic foil bonded on one side of a support backing, said foil and backing being disposed on top of said article support layer with the backing located therebetween, iii. a layer of at least partially transparent and heat shrinkable plastic material disposed on said layer of foil, and iv. a layer of at least partially transparent plastic material disposed on said heat shrinkable layer; and b. compressing said positioned layers with a pressure of between approximately 800 psi and 1,400 psi at a temperature of between approximately 260*F and 300*F for between approximately 16 to 22 minutes, thereby causing i. said layers to bond together, ii. said heat shrinkable material to shrink, and iii. the production of a plurality of randomly located creases in said metallic foil.
