WILLIAM O. JELLEM, OF\ IPASSAIC, NEW JERSEY, ASSIGNOR TO BRIGHTON A CORPORATION OF NEW JERSEY.

BAG, WOVEN FABRIC, .AND METHOD OF MAKING THEM.

Application led J'uly 24, 1923. Serial No. 653,539.

To all whom z't may concer/n Be it known that I, WILLIAM O. EI'iLEME, a citizen of the United States,.resid1n0r at Passaic, iii the county of Passaic and Sotate of New Jersey, have made certain new and useful Improvements in B ags, Woven Fabrics, and Methods of Making Tliem,.of which the following is a specification.

The invention relates to a fabric and more especially to a woven` fabric bag and to the method of making saine. u

Objects and advantages of'the invention will be set forth in part hereinafter and in part will be obvious herefroni, or may be learned by practice with tlie 1nvent1on, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel articles, constructions, arrangements, steps, methods, combinations and improvements herein shown and described.

The accompanying drawings herein referred to and constituting a part hereof, 1llustrate one embodiment of the invention, and together with the description, serve to 'explain the principles of the invention.

Of the drawings n Fig. 1 is a plan ofv a fabricl embodying the invention; t

Fig. 2 is a section taken on the line 2 2 of Fig. 1;

Fig. 3 is a section taken on line 3 3 of Fi 1' Figfli is a section taken on line 4-4 of Fi 1;

lg? ig. 5 is a fragmentary elevation ofl the open end of the bag;

Fig. 6 is adiagrammatic section through Fig. 5; and

Fig. 7 is a diagrammatic plan of the fabric as it comes from the loom with certain parts cut apart.

The present invention is directed to producin a fabric, which may be conveniently style tubular, or two-fold, with intervening single portions woven integrally and simultaneously therewith, and uniting these twofold portions of the integral fabric, and at the same time constituting side-edge portions which are dense, strong, durable, flexible, but non-yielding. In addition thereto,

the fabric at predetermined places longitudi nally thereof, ,is woven transverselyin an integral, transversely disposed portion to unite the two-fold or double portion into a single fabric across the loom, which portion is likewise strong, compact and dense, and which may serve as the bottom of one or a plurality of bagswoven across the Width of the fabric.

Referring by way of example to the accompanying drawings, illustrating one embodiment of the invention, the warp or the portion of the war which is woven into the tubular or two-forfd fabric comprises two series or groups 1 and 2 of yarns, cords, etc., at different levels in the loom,which are preferably relatively large or coarse. These all may be conveniently styled warp A.

At either side of these warp yarns 1 and,

, the side-edge portions` and these are in a single series, that is, at a single level in the loom, preferably close together, and also preferably of relatively small yarn. These may all be conveniently styled warp B. T'hese may be termed fin` or border yarns or warp, in their relation to the bags or tubular fabric produced. Where it is desired to have several articles or units produced transversely of the fabric as it comes from the loom, there may be one or more series of warp B arranged centrally or otherwise medianly between zones of warp A.

The filler yarn 4 is interwoven with all o f the B or iin or border warp yarns, ibut each filler yarn is interwoven with only half of the main or A relatively coarse warp yarns; that is, say the first, third, fifth and so on warp yarns. The filler yarn at the opposite side edge of the fabric is again interwoven with all of the B or fin or b/order, relatively fine warp yarns, and this is likewise true where these warp yarns occur elsewhere across the fabric.

The line filler yarn is likewise interwoven with all of the B or fin or border, relatively fine, warp yarns` and in turning makes a selvage. This filler yarn is then interwoven with the second series of A, that is, relatively coarse warped yarns, constituting the main body of the fabric, which would preferably be second, fourth, sixth and so on.

This filling yarn on again approaching the other side edge of the fabric isinterwoven with all of the fin or border warped yarns in the manner previously described, and on turning again makes a selvage edge as before. Where there are fin, or border MILLS,

.//Referrin yarns arranged in the body of thefabric,

the filler yarn would, as usual, beinterwoven with all said thin or border warp yarns.

more in detail to the method of making t is fabric, sixj harnesses are used, and may be designated from a to f. 'Ihe A warp B is drawn on the first and second the fourth yarn in harness b and so on. That.

is, every other yarn of warp B is\above and below any particular strand of the filling.

lVarp A is then drawn through the third,`

` fourth, fifth and six harnesses, the threads being drawn on the successive harnesses in numerical rotation; As the first'thread on to harness c, the second thread onto harness d; the third thread on to harness e; and the fourththread on to .harness f; the fifth thread on to harness g; and soon for the width of the tube or two-fold fabric. The adjacent zone of warp B is then drawn Aon harnesses a and b in like manner to the first v portion of warp B already described.

B a very The body of the tube or bag is formed by` weaving as follows Pick 1, raise harnesses a and c; pick 2, raise harnesses b and e; pick 3, raise harnesses. a and d ;-pick 4, raise harnesses b and f. This will be repeated in the same manner for the predetermined length of the bag to be formed.

To constitute the integral woven bottom fin or border of the bagq where all the filler yarns are interwoven with all the warp A yarns (designated by C), the manner of the weaving is changed, as follows Pick 1, raise harnesses a, c and f; pick 2, raise harnesses b, d and f; and repeat these operations for the length of this integral interwoven section re uired.

lVhile this exempli es one weave of thev tubular body, this weave may be changed to any other weave desired, and it will be understood that the particular kind of weave, relative coarseness and fiueness and Sizeof yarns is merely exemplary.

vof the fabric.

It is preferable that in the central Sectio few of the relatively fine warp threads are omitted, and the fabric may be slitted along this line to separate the two bags. This is s hown in the central part of Fig. 7. At the bottom part of Fig. 7, two of the bag units are shown cut off transversely as well as slit apart longitudinally. Thus the bags are finished in the loom with t ree woven edges, these edges also presenting'fin o r border protecting and strengthening portions. 0n y one edgle of the bag is left open, which constitutes t e top thereof, and this Amay be folded over and sewn as shown in Figs. 5 and 6. Thus the only finishing-required of the bag is by hemming at the top, and preferably overcasting the innerer nonselvage edge B. It; is also preferable to overcast the outeredge of the fin or border portlon after they have been ulled apart'.

While the process is adapta le to different products it produces aV bag, such as a. laundry bag for washing and drying clothes which is woven shut at the bottom and both sides, requiring hemming at the top onl The bag is reenforced bythe dense flexible fin at the bottom and sides and a plurality of such units can be produced across the loom. The bodyl of the bag may be of a strong open mes to especially adapt it for vlaundry work. The side fins Ibeing of fine yarn make a tight binder which w1ll shrink in water and thus become tighter. The yarns of the finished bag may be dipped or otherwise impregnated with chemical resisting material to lengthen the life of the bag by increasing its resistance to the action of chemicals used in laundrying.

The invention in its border aspects is not limited to the specific mechanisms shown and described but departures may be made therefrom within the scope of the accom panying claims without departing from the principles of the invention and. without sacrificing its chief advantages.

What I claim is 1'. A tubular fabric comprising a portion having two sets of warp yarns, a part of the filler yarns being interwoven with one set of warp yarns and another part of the filler yarns being interwoven with the other set of warp yarns to form a tubular part, and a portion at the side thereof wherein the warp yarns are'relatively fine, and all said filler yarns are linterwoven with said relatively fine warp yarns to constitute a. hard and dense fin.

2. A tubular fabric comprising a portion having two sets of warp yarns, a part of the filler yarns being interwoven with one set of warp yarns and another part of the filler yarns being interwoven with the otherset of warp yarns to form a tubular part, and portions at either side thereof wherein the warp yarns are relatively fine, and all Said filler yarns are interwovenvwith said relativel fine warp yarns to constitute a hard no' and ense fin.

3. A tubular fabric comprising a portion having two sets of warp yarns, a part of the filler yarns being interwoven with one set of warp yarns and another part of the ,filler yarns being interwoven with the other set of warp yarns to form a tubular part, and a portion at the side thereof, and at the edge of the fabric, wherein the warp yarns are relatively fine, and all said filler yarns are interwoven with said relatively fine Warp yarns to constitute a hard and dense selvaged iin. y'

4. A tubular fabric comprising a portion having two sets of warp yarns, a part of the filler yarns being interwoven with one set of warp yarns and another part of the filler yarns being interwoven with the other set of warp yarns to form a tubular part, and portions at either side thereof, and at the edge of the fabric, wherein the warp yarns are relatively fine, and all said filler yarns are interwoven with said relatively fine warp yarns to constitute hard and dense selvaged 5. A woven fabric bag comprising a body part having two sets of warp yarns, a part of the filler yarns being interwoven with one set of Warp yarns and another part of the filler yarns being interwoven with the other set of warp yarns and side portions wherein the warp yarns are relatively very tine, and all the warp yarns are interwoven with all the filler yarns to form dense and hard woven fins at the side edges of the bag, and an end portion wherein all the yarns of the body portion and the side portions are interwoven with all the filler yarns to forrn a woven iin at the bottoni edge of the bag.

6. A woven fabric having central warp yarns in two sets, and side warp yarns which are relatively fine, the filler being in terwoven with all said side warp yarns, but a part only of the filler yarns being interwoven with one set-of the central warp yarns and the other part of the Hller being interwoven with the other set 0f warp yarns, said fabric having portions along its length wherein all the filler yarns are interwoven with allthe warp arns across the fabric.

In testimony wiereof, I have signed niy naine to this specification.
