Abstract

Abstract of the Disclosure A process for severing and heat fusing along the lines of severence, two plastic sheets having flocced surfaces in contact with one another and articles produced thereby. A nylon floccing is applied to one side of foam polyurethane sheets and the surfaces of the sheets with the floccing thereon are placed in contact with the nylon floccing sandwiched therebetween. Heat and pressure is applied by means of a heated dye to areas in which severing and fusion is to take place. The resulting article has a seam therein which comprises a fusion of the plastic material and the floccing material. By means of such process a glove component may be formed with floccing on the inside without the necessity of turning the glove inside out and without the necessity of stitching the seams.
Such glove component is then coated with a waterproof abrasion resistant coating.

Description

FIELD OF INVENTION
This relates to a method of thermally fusing plastic shee-ts coated with a floccing material, while the surfaces bearing the floccing material are in con~act with one another, and to the products thereof.
BACKGROUND OF INVENTION
In the manufacture of plastic articles such as disposable work gloves, it is desirable to ~in;m; ze the number of manual steps involved in the production thereof.

It is also desirable that such gloves have an internal surface which obviates the necessity of the wearer's skin contacting the plastic material directly. This permits the gloves to be slipped on and off more easily and avoids the wet clammy feeling of skin in contact with plastic. The presence of such surface also avoids the occurance of tackiness in the plastic which may occur after a period of wear and adds insulation to the glove.
Heretofore various proposals have been made for manufacturing plastic gloves with liners. Such proposals have included the step of sewing of liners or have formed liners on the outside thereof and hence necessitated the step of turning the glove inside out, to provide an internal liner.
None of the prior art proposals have disclosed a method which would provide in a simple step the cutting and seaming of a glove with a liner on the inside.

.~

f~ q~

It has been found that if it is attempted to form a seal between plastic sheets having conventional floccing material such as rayon or cotton on the surfaces in contact, satisfactory sealing does not take place. The process according to the present invention can be carried out when the materials used result in a proper fusion between the floccing material and the plastic material. It has been found that floccing material consisting of *Nylon and plastic sheet-ing material consisting of polyurethane provide a satisfactory re-lationship between the floccing material and the plastic to produce proper fusion and hence to form a satisfactory seal.
Summary of Invention In accordance with the present invention there is provided a method of thermally sealing together two pieces of plastic sheet material having a ~loccing on one surface thereof, comprising, apply-ing a floccing having a composition which will thermally fuse with said plastic material to one surface of each of said pieces of plas-tic sheet material, placing said surfaces with the floccing thereon in contact with one another, applying heat and pressure to said con-tacting pieces in the areas in which thermal sealing is to take place.
In accordance with another aspect of the present invention there is provided in a method of producing a composite article of cellular plastic sheet material, comprising, applying a nylon floc-cing to a surface of two sheets composed of cellular plastic material which is capable of thermally fusing with said nylon floccing, plac-ing said surfaces of said sheets with the floccing thereon, in con-tact with one another, applying heat and pressure to said contacting sheets in a line, to thereby sever and thermally seal together, said sheets along said line.
In accordance with another aspect of the present invention there is provided in a method of producing a glove having an internal flocced surface, comprising, applying flocclng to a surface of each of two sheets o-E plastic material, said floccing comprising a mater-ial which will thermally fuse with said plastic material, placing said surfaces of said sheets with the -Eloccing thereon in contact with one another, applying heat and pressure in a line corresponding to a contour of at least a portion of the outline of a glove element to thereby thermally sever and seal said sheets together, along said line to form said glove element.
In accordance with another aspect of th~ present invention there is provided a composite article comprising a plurality of pieces of plastic material thermally fused together along seams therein and having a surface covered with floccing material, said seam comprising a fusion of said plastic material and said floccing material.

Figure l(d~ illustrates the assembly of Figure l(c) following a cutting and fusing step.
DETAILED ~ESCRIPTION
While this invention will be described in relation to the manufacture of plastic gloves it will be appreciated that the basic process is suitable for other applieations in which it is desirable to obtain the eutting and/or joining of flocced plastic sheets with the flocced surfaces in contact.
As shown in Figures l(a) and l(b) a cellular plastic sheet 10 is first coated on surface 11 with a Nylon floccing 12.
The plastic sheet 10 is preferably eomposed of cellular polyurethane. The sheet is usually 1/8" and 3/16" in thiekness.
Following the 10ccing step the sheet 10 is placed in contact with a similar sheet 13 which has similarly been coated with Nylon 10ccing 14. As shown in Figure l(c) the sheets 10 and 13 are assembled by placing them in contact with one another with the flocced surfaces 12 and 14 sandwiched between the plastic sheets 10 and 13.
As illustrated in Figure 2 the two sheets are assembled with edges 18 of each, coineiding. The sheets as thus assembled are in eondition for the cutting and sealing step. For this purpose a heated die in the form o an outline of the body of -the glove 17 is applied under pressure against the assembled sheets 10 and 13. The die thus cuts the glove from the assembled sheets and at the same time produces ~ 4 --~L~ 3~

along the line of the cut, a seam 15 consisting of a fusion of the plastic sheet material and the floccing material. The glove 17 is cut from the assembled sheets 10 and 13 in a position so that a cuff opening lg is formed by the edges 18 of the assembled sheets. Since the sheets have not been cut by the heated die along edges 18, there will be no seam in this area.
Thus the glove component 17 illustrated in Figure 3 which is produced by the above described stamping process, will comprise a cellular plastic outer layer with a flocced inner surface. The pieces which form the glove component are attached by a continuous seam 15 (except in the area of cuff opening 19) which comprises a fusion of the plastic and floccing ma-terial. Consequently the glove component thus produced is ready for the next step in the process namely the application of an outer coating, without the need of reversing it. The outer coating will serve to waterproof the glove and to provide an outer surface resistant to abrasion.
In order to coat the glove component 17, it is placed on a forrn 18 and then dipped into a liquid bath consisting of the coating material. Alternatively the coating material may be applied to the form 18 by spraying. The coating material may comprise polyvinyl chloride, neoprene or rubber.
As shown in Figure ~ the glove consists of a cellular plastic sheet material with a flocced surface on the inside. The pieces of the plastic sheet which make up the glove are joined by a continuous seal consisting of a fusion of the plastic material and the floccing material.

L~3 The seam does not have edges projecting inwardly of the glove to produce discomfort to the wearer. The outside of the glove comprises a flexible waterproof coating to provide resistance to abrasion, waterproofing and additional insulation.
As an alternative to forming the cuff of the glove component by having the cuff coincide with edges of the sheets, the glove component may be cut from the sheet elsewhere than adjacent to the edge of the sheet and the cuff opening obtained by cutting the glove component at the cuff area.
