Abstract
Abstract An adhesive bonding method and apparatus includes a pair of opposed web members having confronting surfaces provided with cooperatively engaging hook and loop portions. The hook portion of one confronting surface is saturated with an epoxy resin or the like, and the loop portion of the other confronting surface is saturated with a catalyst for the resin. The web members are urged together to engage the hook and loop portions and to intermix the catalyst and the resin.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
117 words
A method for permanently bonding two objects, comprising the steps of securing a hook fabric portion to one of said objects, securing a loop fabric portion to the other of said objects, said hook and loop portions being adapted for mutual engagement and retention upon impingement, applying a resin compound to one of said portions, applying a resin catalyst to the other of said portions, bringing said objects together to impinge said hook and loop portions and intermix said resin and catalyst, said hook and loop portions mutually engaging to retain said objects together while said resin and catalyst react, thereafter curing said resin and catalyst to form a hardened, fiber reinforced resin bond between said portions.
Claim 2
Independent Claim
117 words
A method for permanently bonding two objects, comprising the steps of securing a hook fabric portion to one of said objects, securing a loop fabric portion to the other of said objects, said hook and loop portions being adapted for mutual engagement and retention upon impingement, applying a resin compound to one of said portions, applying a resin catalyst to the other of said portions, bringing said objects together to impinge said hook and loop portions and intermix said resin and catalyst, said hook and loop portions mutually engaging to retain said objects together while said resin and catalyst react, thereafter curing said resin and catalyst to form a hardened, fiber reinforced resin bond between said portions.
Claim 3
Independent Claim
86 words
A method for permanently bonding two objects, comprising the steps of securing a hook fabric portion to one of said objects, securing a pile fabric portion to the other of said objects, said hook and pile portions being adapted for mutual engagement and retention upon impingement, applying an adhesive compound to said hook and pile portions, bringing together said objects to engage said hook and pile portions to retain said objects together, thereafter curing said adhesive to form a fiber reinforced adhesive bond between said portions.
Claim 4
Independent Claim
86 words
A method for permanently bonding two objects, comprising the steps of securing a hook fabric portion to one of said objects, securing a pile fabric portion to the other of said objects, said hook and pile portions being adapted for mutual engagement and retention upon impingement, applying an adhesive compound to said hook and pile portions, bringing together said objects to engage said hook and pile portions to retain said objects together, thereafter curing said adhesive to form a fiber reinforced adhesive bond between said portions.
Claim 5
Dependent Claim
76 words
A construction for joining permanently two objects, comprising a first member joined to a first object and including a hook fabric portion extending outwardly therefrom, a second member joined to a second object and including a loop fabric portion extending outwardly therefrom, said hook fabric portion engaging said loop fabric portion, and an adhesive compound layer in which said hook and loop fabric portions are embedded, said adhesive compound joining permanently said first and second members.
Claim 6
Dependent Claim
76 words
A construction for joining permanently two objects, comprising a first member joined to a first object and including a hook fabric portion extending outwardly therefrom, a second member joined to a second object and including a loop fabric portion extending outwardly therefrom, said hook fabric portion engaging said loop fabric portion, and an adhesive compound layer in which said hook and loop fabric portions are embedded, said adhesive compound joining permanently said first and second members.
Claim 7
Dependent Claim
17 words
The construction of claim 3, wherein said adhesive compound comprises a cured or catalyzed adhesive resin compound.
