4 . The method of assembling a protective glove as recited in claim 3 , wherein an application temperature of the coating adhesive is in a range of about 100 °C-170 °C.
5 . The method of assembling a protective glove as recited in claim 1 , further comprising the step of pressing inwardly on the first glove against the second glove together for bondingly connecting the first glove to the second glove with the cured coating adhesive.
6 . The method of assembling a protective glove as recited in claim 5 wherein the pressing step comprises applying a pressure inwardly onto the first glove.
7 . The method of assembling a protective glove as recited in claim 1 , wherein the second glove is formed of a protective material.
8 . The method of assembling a protective glove as recited in claim 7 , wherein the protective material is selected from a group consisting of a chemical resistant material, a cut resistant material, a material for thermal protection, a liquid impermeable material, a liquid resistant material, an abrasion resistant material, a puncture resistant material, and a tear resistant material.
9 . The method of assembling a protective glove as recited in claim 7 , wherein the protective material is selected to feature one or more of a group consisting of resistance to chemicals, resistance to cutting, resistance to cold temperatures, resistance to hot temperatures, resistance to liquids, resistance to abrasion, resistance to puncture, resistance to tearing, impermeable to liquids, moisture absorbent, and moisture wicking.
10 . The method of assembling a protective glove as recited in claim 1 , wherein the first glove comprises a protective material selected from a group consisting of a chemical resistant material, a cut resistant material, a material for thermal protection, a liquid impermeable material, a liquid resistant material, an abrasion resistant material, a puncture resistant material, and a tear resistant material.
11 . The method of assembling a protective glove as recited in claim 1 , wherein the protective layer provides a chemical resistant function.
12 . The method of assembling a protective glove as recited in claim 1 , wherein the protective layer provides an abrasion resistant function.
13 . The method of assembling a protective glove as recited in claim 1 , wherein the second glove comprises a cut resistant textile material.
14 . The method of assembling a protective glove as recited in claim 1 , wherein the second glove comprises a thermal resistant textile material.
15 . The method of assembling a protective glove as recited in claim 1 , further comprising the step of heating the glove to about 70 °C to 150 °C for 30 to 180 seconds during the curing of the adhesive coating.
16 . The method of assembling a protective glove as recited in claim 15 , wherein the glove is heated in an oven preheated to about 70 °C to 150 °C.
17 . The method of assembling a protective glove as recited in claim 1 , further comprising the steps of (i) overlying the first glove with a pressure glove, and (ii) pressing the first glove against the second glove during curing.
18 . The method of assembling a protective glove as recited in claim 17 , wherein the pressure glove applies a pressure with a modulus of 5 to 15 megapascals at 100% elongation.
19 . An apparatus for assembly of a glove, comprising:
a first form for receiving a first glove and having five spaced-apart digital carriers with each of the digital carriers receiving a respective digital portion of the first glove;
a second form for receiving a second glove;
a frame to which the first form attaches, said first form movable from a first position with the digital carriers remote from but aligned with respective digital portions of the second form to a second position with the digital portions of the first glove rollingly received on a respective digital portion of the second glove from a respective digital tip to a crotch portion of the second glove,
whereby pulling a cuff portion of the first glove longitudinally past the respective crotch portions of the second glove brings a palm portion and the cuff portion of the first glove into contacting alignment with the second glove; and
an applicator for applying a coating of a tacky adhesive with an open time on an outward surface of the second glove,
whereby the adhesive coating bonds the first glove and the second glove together upon cure of the adhesive coating.
20 . The apparatus for assembly of a glove as recited in claim 19 , further comprising a device for pressing the first glove inwardly against the second glove together after assembly.
21 . The apparatus for assembly of a glove as recited in claim 19 , further comprising a roller attached proximate a distal end of a respective digital carrier for rolling the digital portion of the first glove into contact with the respective digital portion of the second glove.
22 . The apparatus for assembly of a glove as recited in claim 19 , wherein each of the digital carriers comprises an open-end tube sized to receive a respective digital portion of the second form, whereby the tube moving relative to the digital portion rolls the digital portion of the first glove into contact with the digital portion of the second glove.
23 . The apparatus for assembly of a glove as recited in claim 19 , wherein each of the digital carriers comprises:
an elongated rod;
a support at a distal end of the elongated rod;
at least a pair of fingers U-shaped in cross-section disposed in opposing spaced-apart relation to define a channel therebetween to receive a respective digital portion of the second form therein, the pair of fingers pivotally attached at a first end to the support, whereby the fingers move apart while receiving a respective digital portion of the second form inwardly in the channel by the moving of the first form relative to the second form to roll the digital portion of the first glove on the first form into contact with the digital portion of the second glove on the second form.
24 . The apparatus for assembly of a glove as recited in claim 23 , wherein the fingers are pivotally biased towards each other by a spring.
