Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
199 words
A carpeting strip having integral joining means comprising, a wear layer having a bottom surface and opposed side edges, an adhesive coating disposed against said bottom surface along at least one of said side edges, said coating having an outer portion and an inner portion, a release tape disposed against said outer portion and having an edge disposed in alignment with said side edge, said release tape defining a free part of said wear layer disposed thereagainst, and a compressible backing material bonded against said bottom surface and against said inner portion of said adhesive coating while having a portion of said backing material isolated from said wear layer by said tape, said carpeting strip being particularly adapted to have said one side edge thereof disposed in abutting relation against a substantially identical carpeting strip having a substantially identical side edge by removing said tape from said carpeting strip and a similar tape from against an outer portion of an adhesive coating of said identical carpeting strip and bonding said outer portions of said adhesive coatings against support means bridging said isolated portion of backing material and a similar isolated portion of backing material of said identical carpeting strip.
Claim 2
Dependent Claim
199 words

Claim 10
Independent Claim
208 words
A method of making a carpeting strip having integral joining means, said method comprising the steps of, providing a wear layer having a bottom surface and opposed side edges, applying an adhesive coating against said bottom surface along at least one of said side edges, said coating having an outer portion and an inner portion, disposing a release tape against said outer portion with an edge thereof in alignment with said side edges, said release tape defining a free part of said wear layer disposed thereagainst, and bonding a compressible backing material against said bottom surface and against said inner portion of said adhesive coating while having a portion of said backing material isolated from said wear layer by said tape, said carpeting strip being particularly adapted to have said one side edge thereof disposed in abutting relation against a substantially identical carpeting strip having a substantially identical side edge by removing said tape from said carpeting strip and a similar tape from against an outer portion of an adhesive coating of said identical carpeting strip and bonding said outer portions of said adhesive coatings against support means bridging said isolated portion of backing material and a similar isolated portion of backing material of said identical carpeting strip.
Claim 11
Independent Claim
208 words
A method of making a carpeting strip having integral joining means, said method comprising the steps of, providing a wear layer having a bottom surface and opposed side edges, applying an adhesive coating against said bottom surface along at least one of said side edges, said coating having an outer portion and an inner portion, disposing a release tape against said outer portion with an edge thereof in alignment with said side edges, said release tape defining a free part of said wear layer disposed thereagainst, and bonding a compressible backing material against said bottom surface and against said inner portion of said adhesive coating while having a portion of said backing material isolated from said wear layer by said tape, said carpeting strip being particularly adapted to have said one side edge thereof disposed in abutting relation against a substantially identical carpeting strip having a substantially identical side edge by removing said tape from said carpeting strip and a similar tape from against an outer portion of an adhesive coating of said identical carpeting strip and bonding said outer portions of said adhesive coatings against support means bridging said isolated portion of backing material and a similar isolated portion of backing material of said identical carpeting strip.
