POLYMERIC SHELL ADHERENTLY SUPPORTED BY A LINER AND A METHOD OF MANUFACTURE
First Claim
1. An article comprising:
- a) a first cured, liquid-impervious polymeric shell substantially free from defects;
b) a cut-resistant liner;
c) a first non-tacky, thermoplastic adhesive layer placed between the first shell and the first cut-resistant liner;
d) a second adhesive layer; and
e) a second shell,wherein the first adhesive layer creates a bond between the first shell and the cut-resistant liner and the second adhesive layer creates a bond between the second shell and the cut-resistant liner and the first adhesive layer and second adhesive layer are melted and solidified to create a non-tacky bond between the first shell, the second shell and the cut-resistant liner,whereby the cut-resistant liner supports and limits stretchability of the first shell and the second shell, thereby preventing adhesive delamination between the first adhesive layer, the second adhesive layer and either of the first shell, the second shell and the cut-resistant liner, or both.

Abstract
An article comprising at least one cured, liquid-impervious polymeric shell substantially free from defects, at least one liner, and a non-tacky, thermoplastic adhesive layer between the shell and the liner, wherein the adhesive layer is melted and solidified to create a non-tacky bond between the shell and the liner, which can be moisture-absorbing or cut-resistant, whereby the liner supports and limits stretch ability of the shell, thereby preventing adhesive delamination between the adhesive layer and either of the shell and/or the liner; a method for the manufacture of an article comprising a supported, polymeric shell, such as a glove, a gauntlet, an apron, or a boot, comprising providing a cured, liquid-impervious, polymeric shell, providing a knitted/woven liner, incorporating a non-tacky, thermoplastic adhesive layer between the shell and the liner, such as by hot-melt spraying, dry-powder spraying or fiber-coating, creating intimate contact between the shell, the adhesive layer, and the liner, subjecting the shell, the adhesive layer, and the liner to infrared radiation to melt the adhesive layer and create a bond between the shell and the liner, and cooling the shell; as well as other methods.

3. An article comprising:
at least one cured, liquid-impervious polymeric shell substantially free from defects bonded to at least one liner by a thermoplastic adhesive layer disposed between the at least one shell and the least one liner and partially penetrated into the at least one liner, the adhesive layer having a greater stretch ability than the at least one liner and the at least one shell having a stretch ability that is greater than or equal to the stretch ability of the adhesive layer. - View Dependent Claims (4, 5, 6, 7, 8, 9)
