Abstract
Abstract A carpet seaming tape comprising a tape base with yarns thereon and having a layer of adhesive thereover with a plurality of spaced apart rows of adhesive formed thereon and extending longitudinally along the tape. The yarns have a heat sealant emulsion rolled onto their backs. The layer and rows of adhesive are melted upon the application of heat, and the heat sealant maintains the adhesive above the tape base so as to be available for securement to the carpet. The backs of two adjacent portions of carpet are then pressed against the tape and are bonded thereto providing a seamless appearance.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
A thermoadhesive carpet seaming tape including a thin and flexible tape, and a layer of solidified adhesive, said layer having embossed thereon rows of solidified adhesive spaced apart from each other such that when heat is applied to said solidified adhesive, said rows and said layer will melt into a continuous layer, thereby placing the tape in condition to be bonded to the backs of pieces of carpet which are seCured thereto, said thin and flexible tape including a plurality of filaments extending transversely on said tape, said layer of solidified adhesive embedding said filaments.
Claim 2
Dependent Claim
95 words
A thermoadhesive carpet seaming tape including a thin and flexible tape, and a layer of solidified adhesive, said layer having embossed thereon rows of solidified adhesive spaced apart from each other such that when heat is applied to said solidified adhesive, said rows and said layer will melt into a continuous layer, thereby placing the tape in condition to be bonded to the backs of pieces of carpet which are seCured thereto, said thin and flexible tape including a plurality of filaments extending transversely on said tape, said layer of solidified adhesive embedding said filaments.
Claim 3
Dependent Claim
20 words
A thermoadhesive carpet seaming tape according to claim 1, further including a plurality of yarns extending longitudinally along said tape.
Claim 4
Dependent Claim
28 words
A thermoadhesive carpet seaming tape according to claim 2, wherein two of said plurality of yarns are of a distinctive color to indicate the center of said tape.
Claim 5
Dependent Claim
38 words
A thermoadhesive carpet seaming tape according to claim 1, wherein the adhesive layer between two sets of rows is of a bright color whereby proper heating of said adhesive causes said bright color to spread out and fade.
Claim 6
Dependent Claim
20 words
A thermoadhesive carpet seaming tape according to claim 1, further including an emulsion applied to the back of said yarns.
Claim 7
Dependent Claim
120 words
A thermoadhesive carpet seaming tape having means to visually indicate its readiness to make an effective bond with the backs of the abutting pieces of carpet, said carpet seaming tape comprising a relatively flexible, elongated member having high tensile strength and having solidified flexible thermoplastic adhesive material adhered to one side of it along its length, said thermoplastic adhesive having at least one relatively elongated, narrow line of a fugitive coloring dye therein, said thermoplastic adhesive being adapted to melt upon the application of heat and said fugitive dye being of a type that the color disappears upon melting of the thermoplastic adhesive to indicate to an operator the speed at which to apply the tool for melting the adhesive.
Claim 8
Dependent Claim
120 words
A thermoadhesive carpet seaming tape having means to visually indicate its readiness to make an effective bond with the backs of the abutting pieces of carpet, said carpet seaming tape comprising a relatively flexible, elongated member having high tensile strength and having solidified flexible thermoplastic adhesive material adhered to one side of it along its length, said thermoplastic adhesive having at least one relatively elongated, narrow line of a fugitive coloring dye therein, said thermoplastic adhesive being adapted to melt upon the application of heat and said fugitive dye being of a type that the color disappears upon melting of the thermoplastic adhesive to indicate to an operator the speed at which to apply the tool for melting the adhesive.
Claim 9
Dependent Claim
26 words
A tape as in claim 6, wherein said thermoplastic adhesive is in the form of a relatively thin continuous layer having elongated, parallel ribs formed thereon.
Claim 10
Dependent Claim
157 words
A thermoadhesive carpet seaming tape including a thin and flexible tape, and a layer of solidified adhesive adhered to one side of said thin and flexible tape, said layer having embossed thereon rows of solidified adhesive spaced apart from each other such that when heat is applied to said solidified adhesive, said rows and said layer will melt into a continuous layer, thereby placing the tape in condition to be bonded to the backs of pieces of carpet which are secured thereto, a plurality of yarns extending longitudinally along said tape, said layer of solidified adhesive being mounted on top of said yarns, said adhesive layer adhering to said transverse and longitudinal yarns and to said tape, an emulsion applied to the back of said yarns, said emulsion being a polyvinyl acetate utilized as a heat sealant such that when said solidified adhesive melts, said emulsion prevents said adhesive from embedding into said thin and flexible tape.
Claim 11
Dependent Claim
157 words
A thermoadhesive carpet seaming tape including a thin and flexible tape, and a layer of solidified adhesive adhered to one side of said thin and flexible tape, said layer having embossed thereon rows of solidified adhesive spaced apart from each other such that when heat is applied to said solidified adhesive, said rows and said layer will melt into a continuous layer, thereby placing the tape in condition to be bonded to the backs of pieces of carpet which are secured thereto, a plurality of yarns extending longitudinally along said tape, said layer of solidified adhesive being mounted on top of said yarns, said adhesive layer adhering to said transverse and longitudinal yarns and to said tape, an emulsion applied to the back of said yarns, said emulsion being a polyvinyl acetate utilized as a heat sealant such that when said solidified adhesive melts, said emulsion prevents said adhesive from embedding into said thin and flexible tape.
