Abstract
Abstract The present invention comprises an adhesive sheet including a supporting sheet made of thermoplastic resinous material, a plurality of artificial filament yarns arranged substantially parallel to the longitudinal direction of the supporting sheet with at least about one-half of the cross-section of the yarn being buried in and thus strongly adhered to one side of the supporting sheet and an adhesive layer provided on the filament containing side of the supporting sheet.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
114 words
A flexible pressure sensitive adhesive sheet including a supporting sheet made of a thermoplastic resinous material, a plurality of artificial filament yarns arranged substantially parallel to the longitudinal direction of said supporting sheet with a predetermined space provided therebetween, said filament yarns being buried in one side of said supporting sheet up to at least about one-half of their cross-sections, thereby strongly adhering the filament yarns to said sheet, and a pressure sensitive adhesive layer provided on said filament yarn containing side of the sheet, whereby the artificial filament yarns are embedded in both the supporting sheet and the adhesive layer, thereby providing a high tensile strength in the longitudinal direction of the tape.
Claim 2
Dependent Claim
114 words
A flexible pressure sensitive adhesive sheet including a supporting sheet made of a thermoplastic resinous material, a plurality of artificial filament yarns arranged substantially parallel to the longitudinal direction of said supporting sheet with a predetermined space provided therebetween, said filament yarns being buried in one side of said supporting sheet up to at least about one-half of their cross-sections, thereby strongly adhering the filament yarns to said sheet, and a pressure sensitive adhesive layer provided on said filament yarn containing side of the sheet, whereby the artificial filament yarns are embedded in both the supporting sheet and the adhesive layer, thereby providing a high tensile strength in the longitudinal direction of the tape.
Claim 3
Dependent Claim
17 words
The pressure sensitive adhesive sheet according to claim 1, wherein the artificial filament yarn is a monofilament.
Claim 4
Dependent Claim
25 words
The pressure sensitive adhesive sheet according to claim 1, wherein the artificial filament yarn is a single filament yarn twisted with a plurality of monofilaments.
Claim 5
Dependent Claim
27 words
The pressure sensitive adhesive sheet according to claim 1, wherein said artificial filament yarn is a combined filament yarn twisted with a plurality of single filament yarns.
Claim 6
Dependent Claim
