Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
111 words
A continuous process for making a patterned composite fabric from a laminated fabric having a scrim fabric on one side and a decorative fabric on the other side thereof separated therefrom by a layer of flexible foam material comprising the steps of : continuously supplying the laminated fabric into a heated oven to tackify the flexible foam material, continuously passing the laminated fabric between the nip of a cooled pattern roll and a back-up roll to simultaneously depress the decorative fabric into and emboss the flexible foam material and cool the laminate to provide a permanent pattern in the surface of the decorative fabric and continuously taking up the patterned fabric.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
11 words
The process of claim 1 wherein the backup roll is cooled.
Claim 4
Dependent Claim
20 words
The process of claim 2 wherein the temperature of the cooled rolls is maintained in the range of 68°-70° F.
Claim 5
Dependent Claim
50 words

Claim 7
Dependent Claim
19 words
The process of claim 5 wherein the heated oven ismaintained at a temperature in the range of 340°-360° F.
Claim 8
Dependent Claim
21 words
The process of claim 6 wherein the cooled pattern roll is maintained at a temperature in the range of 68°-70° F.
Claim 9
Dependent Claim
21 words
The process of claim 4 wherein the cooled pattern roll is maintained at a temperature in the range of 68°-70° F.
Claim 10
Dependent Claim
11 words
The process of claim 8 wherein the backup roll is cooled.
Claim 11
Dependent Claim
21 words
The process of claim 9 wherein the temperature of the cooled backup roll is maintained in the range of 68°-70° F.
Claim 12
Dependent Claim
57 words
A patterned, laminated fabric for use as a wall panel fabric comprising: a scrim fabric, a flexible foam material laminated on one side to said scrim fabric and a decorative fabric laminated to the other side of the flexible foam material, said decorative fabric and said flexible foam material having identical patterns formed in the surface thereof.
Claim 13
Dependent Claim
57 words
A patterned, laminated fabric for use as a wall panel fabric comprising: a scrim fabric, a flexible foam material laminated on one side to said scrim fabric and a decorative fabric laminated to the other side of the flexible foam material, said decorative fabric and said flexible foam material having identical patterns formed in the surface thereof.
Claim 14
Dependent Claim
15 words
The fabric of claim 11 wherein said scrim fabric and said decorative fabric are woven.
Claim 15
Dependent Claim
20 words
The fabric of claim 12 wherein said scrim fabric and said decorative fabrics are composed of substantially all polyester yarn.
Claim 16
Dependent Claim
12 words
