Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
113 words
A method of making an elastomer coated fabric container comprising coating a fabric with a curable elastomer, curing the curable elastomer coating on the fabric, cutting a panel from said elastomer coated fabric either before or after the curing step, assembling said panels of cured elastomer coated fabric into a container by placing each edge of the panel in overlapping relationship with another edge, positioning a preformed strip or film of an adhesive composed of an elastomer and a thermosetting resin between the edges in overlapping relationship and pressing said edges under pressure for at least two minutes at a temperature and pressure sufficient to cause a bond to form between each panel.
Claim 2
Independent Claim
113 words
A method of making an elastomer coated fabric container comprising coating a fabric with a curable elastomer, curing the curable elastomer coating on the fabric, cutting a panel from said elastomer coated fabric either before or after the curing step, assembling said panels of cured elastomer coated fabric into a container by placing each edge of the panel in overlapping relationship with another edge, positioning a preformed strip or film of an adhesive composed of an elastomer and a thermosetting resin between the edges in overlapping relationship and pressing said edges under pressure for at least two minutes at a temperature and pressure sufficient to cause a bond to form between each panel.
Claim 3
Dependent Claim
20 words
The method of claim 1 wherein the adhesive is a blend of a butadiene acrylonitrile rubber and a phenolic resin.
Claim 4
Dependent Claim
20 words
The method of claim 2 wherein the adhesive contains 5 to 80 percent resin and 95 to 20 percent rubber.
Claim 5
Dependent Claim
27 words
The method of claim 1 wherein the adhesive film is applied while supported on a releasable substrate and the substrate is removed to expose the adhesive film.
