Abstract
Abstract A method of making fabric-lined elastomeric articles of wear is disclosed which includes forming an elastomeric article on a form or mold, applying a pressure-sensitive adhesive to the article while on the form, drying the adhesive, applying a lubricant over the adhesive, positioning a preformed liner over the lubricated adhesive, removing the lubricant, and removing the lined article from the form and turning it inside-out.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
109 words
A method of making a lined elastomeric article comprising the steps of applying a coating of adhesive in liquid state to an elastomeric article on a form, drying the adhesive on the article, thereafter applying a preformed lining over the article and the adhesive coating to adhesively connect the lining to the article including the steps of employing a lubricant between the adhesive coating and the inner surface of the lining to facilitate applying the lining over the adhesive coating and article, and thereafter drying the lining and the article on the form, and removing the article with the lining from the form to provide the lined elastomeric article.
Claim 2
Independent Claim
109 words
A method of making a lined elastomeric article comprising the steps of applying a coating of adhesive in liquid state to an elastomeric article on a form, drying the adhesive on the article, thereafter applying a preformed lining over the article and the adhesive coating to adhesively connect the lining to the article including the steps of employing a lubricant between the adhesive coating and the inner surface of the lining to facilitate applying the lining over the adhesive coating and article, and thereafter drying the lining and the article on the form, and removing the article with the lining from the form to provide the lined elastomeric article.
Claim 3
Dependent Claim
13 words
The method of claim 1 wherein said adhesive is a pressure sensitive adhesive.
Claim 4
Dependent Claim
37 words
The method of claim 1 wherein said step of drying the lining and the article on the form includes positioning the form with the article and lining thereon in an oven to dry the article and lining.
Claim 5
Dependent Claim
19 words
The method of claim 1 further including the step of removing the lubricant after the lining has been applied.
Claim 6
Dependent Claim
35 words
The method of claim 4 wherein the step of removing the lubricant includes the step of washing the form with the lining thereon with a liquid before drying the lining and article on the form.
Claim 7
Dependent Claim
17 words
The method of claim 5 wherein the lubricant is an aqueous solution of a soap or detergent.
Claim 8
Dependent Claim
42 words
The method of claim 1 wherein the step of removing the article from the form includes inverting it so that the interior side of the article when on the form is the exterior side of the article when removed from the form.
Claim 9
Dependent Claim
21 words
The method of claim 1 wherein the lining is a fabric member having a shape similar to that of the article.
Claim 10
Dependent Claim
11 words
The method of claim 8 wherein the article is a glove.
Claim 11
Dependent Claim
58 words
The method of claim 1 wherein the step of providing the elastomeric article on the form comprises the steps of dipping the form into a container of elastomeric material, and removing the form from the container with a layer of elastomeric material thereon, and at least partially curing the layer on the form before said coating applying step.
Claim 12
Dependent Claim
60 words
The method of claim 10 wherein said layer of elastomeric material on the form is only partially cured when said steps of applying the coating of adhesive and of applying the lining are performed, and further including the step of further curing said layer after said steps of applying the coating of adhesive and of applying the lining are performed.
Claim 13
Dependent Claim
64 words
The method of claim 4 wherein said adhesive is a liquid resin type pressure sensitive adhesive when the article is coated therewith and when dry has an outer surface which is tacky for an indefinite length of time, said surface when said lubricant is applied thereto loses its tackiness but regains its tackiness when said lubricant is removed and the adhesive surface is dry.
Claim 14
Dependent Claim
13 words
The method of claim 5 wherein the elastomeric material is a latex material.
Claim 15
Dependent Claim
13 words
The method of claim 13 wherein said latex material is a butadiene acrylonitrile.
Claim 16
Dependent Claim
13 words
The method of claim 13 wherein said lining is a singlepiece cloth member.
Claim 17
Dependent Claim
17 words
The method of claim 15 wherein the article is a glove, and said lining is a glove.
Claim 18
Dependent Claim
22 words
The method of claim 3 wherein the lubricant includes water and a slicking material and is removed from the forms by water.
Claim 19
Dependent Claim
34 words
The method of claim 17 wherein the lubricant is removed by spraying water against the liner in a direction to urge the liner against the form prior to positioning the form in said oven.
Claim 20
Independent Claim
179 words
A method of making a fabric-lined glove comprising the steps of forming a latex glove body on a glove form including the step applying a latex coagulant to the surface of a glove form, drying the coagulant on the form, dipping the coagulant coated form into a container of latex to provide a layer of latex thereon, partially drying the latex layer, leaching the coagulant from the form, at least partially curing the layer of latex, thereafter applying a coating of a liquid pressure sensitive adhesive to the outer surface of the latex, drying the adhesive coating, applying a lubricant to the outer surface of the adhesive coating, slipping a fabric liner onto the form into snug contact relation with the lubricated adhesive coating, rinsing the lubricant from the form, drying the liner, removing the latex layer with the liner adhesively connected thereto from the form to provide a latex glove, and turning the latex glove inside out so that the latex layer is on the exterior side and the liner on the interior side of the latex glove.
Claim 21
Independent Claim
179 words
A method of making a fabric-lined glove comprising the steps of forming a latex glove body on a glove form including the step applying a latex coagulant to the surface of a glove form, drying the coagulant on the form, dipping the coagulant coated form into a container of latex to provide a layer of latex thereon, partially drying the latex layer, leaching the coagulant from the form, at least partially curing the layer of latex, thereafter applying a coating of a liquid pressure sensitive adhesive to the outer surface of the latex, drying the adhesive coating, applying a lubricant to the outer surface of the adhesive coating, slipping a fabric liner onto the form into snug contact relation with the lubricated adhesive coating, rinsing the lubricant from the form, drying the liner, removing the latex layer with the liner adhesively connected thereto from the form to provide a latex glove, and turning the latex glove inside out so that the latex layer is on the exterior side and the liner on the interior side of the latex glove.
Claim 22
Dependent Claim
16 words
The method of claim 19 wherein said lubricant is an aqueous solution including sodium alkyl sulfate.
Claim 23
Dependent Claim
41 words
The method of claim 19 further including the step of placing the form with the latex layer and liner, after said lubricant rinsing step, into an oven to effect said drying of the liner and to further cure the latex layer.
Claim 24
