Abstract
Abstract An improved slip and/or skid resistant surface is provided for work gloves, work shoes, floor coverings in work areas and the like. The surface of the invention provides a porous gripping surface particularly useful in greasy and oily environments where it is necessary for a workman to be able to grip mechanical devices or loose objects having a coating of oil or grease. The surface of the invention is a foam surface laminated to a substrate. The foam, prior to lamination, may be foamed with varying amounts of air depending upon the degree of abrasion resistance required. The foaming may be by mechanical or chemical means.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
139 words
A method for producing a laminate useful in providing a slip resistant oil grip surface for gloves, characterized by the steps of (a) selecting in a first selecting step a glove liner comprised of a web which is a member selected from the group consisting of a fibrous non-woven web, a woven web, and a knitted web; (b) selecting in a second selecting step a material to be applied as a foamed layer to at least one surface of said glove liner from said first selecting step; (c) foaming said member from said second selecting step to an air content within the range of between about 10 and 65 percent; (d) applying said member from said foaming step to the said at least one surface of said glove liner; and (e) curing said foamed member from said applying step.
Claim 2
Independent Claim
139 words
A method for producing a laminate useful in providing a slip resistant oil grip surface for gloves, characterized by the steps of (a) selecting in a first selecting step a glove liner comprised of a web which is a member selected from the group consisting of a fibrous non-woven web, a woven web, and a knitted web; (b) selecting in a second selecting step a material to be applied as a foamed layer to at least one surface of said glove liner from said first selecting step; (c) foaming said member from said second selecting step to an air content within the range of between about 10 and 65 percent; (d) applying said member from said foaming step to the said at least one surface of said glove liner; and (e) curing said foamed member from said applying step.
Claim 3
Dependent Claim
30 words

Claim 6
Independent Claim
131 words
A method for producing a laminate useful in providing a slip resistant oil grip surface for boots, characterized by the steps of (a) selecting in a first selecting step a boot comprised of a web which is a member selected from the group consisting of a fibrous non-woven web, a woven web, and a knitted web; (b) selecting in a second selecting step a material to be applied as a foamed layer to the sole of said boot from said first selecting step; (c) foaming said member from said second selecting step to an air content within the range of between about 10 and 65 percent; (d) applying said member from said foaming step to the said sole of said boot; and (e) curing said foamed member from said applying step.
Claim 7
Independent Claim
131 words
A method for producing a laminate useful in providing a slip resistant oil grip surface for boots, characterized by the steps of (a) selecting in a first selecting step a boot comprised of a web which is a member selected from the group consisting of a fibrous non-woven web, a woven web, and a knitted web; (b) selecting in a second selecting step a material to be applied as a foamed layer to the sole of said boot from said first selecting step; (c) foaming said member from said second selecting step to an air content within the range of between about 10 and 65 percent; (d) applying said member from said foaming step to the said sole of said boot; and (e) curing said foamed member from said applying step.
Claim 8
Independent Claim
187 words
A method for producing a laminate useful in providing a slip resistant oil grip surface, for wearing apparel, floor coverings and the like, characterized by the steps of (a) selecting in a first selecting step a substrate comprised of a web which is a member selected from the group consisting of a fibrous non-woven web, a woven web, and a knitted web; (b) selecting in a second selecting step a material to be applied as a foamed layer to one surface of said substrate from said first selecting step; (c) selecting in a third selecting step a material to be applied as a moisture barrier coating to one surface of said substrate from said first selecting step; (d) coating said one surface of said substrate with said moisture barrier material from said third selecting step; (e) foaming said member selected from said second selecting step to an air content within the range of between about 10 and 65 percent; (f) applying said member from said foaming step to said moisture barrier coated surface from said coating step; and (g) curing said foamed member from said applying step.
Claim 9
Independent Claim
187 words
A method for producing a laminate useful in providing a slip resistant oil grip surface, for wearing apparel, floor coverings and the like, characterized by the steps of (a) selecting in a first selecting step a substrate comprised of a web which is a member selected from the group consisting of a fibrous non-woven web, a woven web, and a knitted web; (b) selecting in a second selecting step a material to be applied as a foamed layer to one surface of said substrate from said first selecting step; (c) selecting in a third selecting step a material to be applied as a moisture barrier coating to one surface of said substrate from said first selecting step; (d) coating said one surface of said substrate with said moisture barrier material from said third selecting step; (e) foaming said member selected from said second selecting step to an air content within the range of between about 10 and 65 percent; (f) applying said member from said foaming step to said moisture barrier coated surface from said coating step; and (g) curing said foamed member from said applying step.
