Abstract
Abstract A fastening member and a method for applying a fastening member to a substrate is described. The method comprises coating the surface of a substrate with an adhesive, activating the adhesive on a fastening tape member and then bringing the adhesive coated surfaces into face-to-face relationship with sufficient pressure to firmly affix the tape member to the substrate.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
134 words
A method for securing a fastening member to a substrate, said member having projecting from one surface thereof a multiplicity of hooking elements and having coated on the opposite surface thereof an adhesive film, comprising the steps of: a. applying a synthetic resin-based adhesive film on a surface portion of the substrate; b. heating the adhesive and applying sufficient pressure to coat the surface portion of the substrate with the adhesive; c. placing a release backing over the adhesive on the fastening member; d. heating the adhesive on the fastening member; e. removing the release backing from the fastening member; and f. bringing the adhesive coated surface of the fastening member into face-to-face contact with the adhesive coated surface of the substrate with sufficient pressure to firmly affix the fastening member to the substrate.
Claim 2
Independent Claim
134 words
A method for securing a fastening member to a substrate, said member having projecting from one surface thereof a multiplicity of hooking elements and having coated on the opposite surface thereof an adhesive film, comprising the steps of: a. applying a synthetic resin-based adhesive film on a surface portion of the substrate; b. heating the adhesive and applying sufficient pressure to coat the surface portion of the substrate with the adhesive; c. placing a release backing over the adhesive on the fastening member; d. heating the adhesive on the fastening member; e. removing the release backing from the fastening member; and f. bringing the adhesive coated surface of the fastening member into face-to-face contact with the adhesive coated surface of the substrate with sufficient pressure to firmly affix the fastening member to the substrate.
Claim 3
Dependent Claim
31 words
The method according to claim 1 wherein the film of thermoplastic adhesive applied to the substrate is initially coated on a release backing which is removed after heating the thermoplastic adhesive.
Claim 4
Dependent Claim
20 words
The method according to claim 2 wherein the adhesive coating on the substrate is heated to at least 300* F.
Claim 5
Dependent Claim
22 words
The method according to claim 3 wherein the adhesive film coating on the fastener member is heated to at least 300* F.
Claim 6
Dependent Claim
12 words
A method according to claim 1 wherein the substrate is a fabric.
Claim 7
Dependent Claim
12 words
A method according to claim 1 wherein the release backing is paper.
Claim 8
Independent Claim
167 words
A method for securing a fastening member to a fabric substrate said member having projecting from one surface thereof a multiplicity of hooking elements and having coated on the opposite thereof an adhesive film, comprising the steps of: a. contacting the fabric substrate with a film of a thermoplastic adhesive coated on a release backing; b. heating the adhesive to a temperature of about 300* F to about 350* F and applying a sufficient pressure to coat the substrate with the adhesive; c. removing the release backing from the adhesive coated substrate; d. placing the release backing over the adhesive on the fastening member; e. heating the adhesive on the fastening member to a temperature of above 300* F to about 350* F; f. removing the release backing from the fastening member; and g. bringing the adhesive coated surface of the substrate and the adhesive coated surface of the fastening member into face-to-face relationship with sufficient pressure to firmly affix the fastening member to the fabric substrate.
