Abstract
Abstract A preformed flock lined rubber-like glove has its cuff folded back to expose the flocked lining and is mounted in a rotating support. A spray nozzle deposits a band of the hot-melt adhesive on the flocked lining of the exposed and rotating cuff. The hot-melt adhesive is a combination of a hot-melt adhesive resin and a uniform dispersion of small particles which create heat in the presence of a high frequency magnetic field. The hot-melt adhesive is allowed to solidify to a solid mass. The glove is telescoped downwardly onto a polyethylene sleeve supported on a rigid form and the cuff is unfolded to place the adhesive into engagement with the sleeve. A high frequency unit includes a high frequency coil having a pair of conducting bars at least one of which is movable. The glove and sleeve subassembly is clamped between the conducting bars and the coil is energized from a high frequency source. The fine particles are activated to heat the hot-melt band simultaneously with application of pressure. The hot-melt adhesive forms a hermetic adhesive bond between the flocked glove and the polyethylene sleeve.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
184 words
The method of joining a flocked glove of a rubber-like shell and a flocked lining to a tubular plastic number, said glove having a cuff portion having an inner surface including said flocked lining, comprising mixing a hot-melt adhesive including a hot-melt adhesive resin and sub-micron particles, said particles generating heat in the presence of an RF magnetic field, folding said cuff portion backwardly to expose the inner surface, supporting said glove with the cuff portion folded backwardly to expose the lining, applying a band of said hot-melt adhesive mixture in molten form to create a layer of adhesive on said exposed flocked lining of said cuff portion, solidifying said layer on said glove, placing the cuff portion onto a flat member with the layer abutting the flat member to form a sub-assembly, mounting of said sub-assembly in a high frequency induction unit, applying pressure across said members and energizing of said induction unit to create a high frequency magnetic field across said cuff portion and thereby remelting of said hot-melt adhesive and connecting the glove to said tubular member with an airtight connection.
Claim 2
Independent Claim
