MASSACHUSETTS, ASSIGLTOR To NITED ELASTICCORPORATION, or EAS'IHAMBTON, MAS5ACHUSETTS, A CORPORATION or MASSACHUSETTS WEBBIN G Application filed November 24, 1931." Serial No. 577,073.

The present invention relates to woven elastic webbing and more particularly to the'novel weave thereof.

Among the objects of the invention are the production of a loop edge providing a lace efiect along the edge' of the fabric which however is not necessarily confined to any particular weave of fabric, but may be used .on any elastic fabric.

Another object is to providein such a weave an arrangement in which the lace or loop threads lay straight during the process of weaving, but in which, as the web contracts in the process of weaving the fabric, the loop or lace effect will be produced, due to the novel manner of attaching the lace threads to the body of the web.

' This effect may be increased or decreased as desired, by shortening or lengthening the distance between the points-bfattachment of the lace threads to the body.

Another object is to provide a' loop or lace edge so connected to the main woven fabric as to prevent unravelling or detachment therefrom.

Still another object is to form an edge, having the appearance of a crocheted edge, but which is Woven into the fabric during the weaving of the body of the fabric.

The invention further contemplates provision of a novel Weave in thebody of the fabric.

Various novel and ornamental effects may be produced by using lace threads of desired colors or by using lace threads of a color contrasting to thatof the main Weave.

To the attainment of the above, and other objects which will appear as the description proceeds, reference may be 'made to the accompanying drawings, in which Fig.1 is an enlarged face view of a fabric embodying the invention, with the webextended and the weft thread laid in without tension; and e v Fig. 2 is a similar-view showing the'lace efi'ect as it appears in actual operation .on the loom. r

Referring more specifically to the drawings, wherein like reference numerals desig nate like parts, Figure l'illustratesla web or fabric having a filling or weft 10, a series of rubber warps 12, interspersed with binder' warps 14 and centerwarpslG. 18 designates the edge wires. A series of loop or lace forming threads 20, 21 and 22, prefedge or selvage ofthe fabric.

As'the weft 10 passes back and forth transversely of the web, return loops 24 and 26 will be formed, and the innermost lace thread 20 is laid in to pass over the pair of wefts forming loop 24, and underthe adjacent pair, forming loop 26. The intermediate thread 21 passes under the loop 24 and over the loop 26, while the outer thread 22 passes through both of the loops 24 and 26. In Fig. 1 the weft 10 is illustrated as laid in without tension to illustrate as fully as possible the manner in "which the lace and weft threads are interlaced and showing how theyare placed inrelation to each other in this particular weave. I

In Figure 2 the fabric and lace effect is illustrated as it appears while being woven, the elastic web being under weaving tension on the loom, the weft thread being under regular shuttle tension and the outside lace thread being pulledinto the selvage or edge of the web. This outside thread 22 will havebeen pulled through, and not around the other two lace threads 20 and 21, andthe erably three in a'row, are laid inalong each 1 two inside lace threads 20 and 21 will have through the end loops formed by said adj acent pairs of weft threads, said Wefts under normal tension being effective to draw in said warp threads and bind them at spaced intervals into the selvage of the fabric. r

2. The method of weaving a fabric incorporating elastic warps, which comprises forming pairs of weft loops by weft re- ;turns at spaced intervals along the fabric,

of slightly greater length than an intermediate weft,laying a lace formingthread over one loop of each pair and under the adjacent loop, laying a second lace forming thread under said first mentioned loop of each pair and over the second loop, laying a third lace forming thread through both of the loops of :each pair, said loops, under normal tension, being effective to draw in said lace forming threads and bind them at spaced intervals into the fabric.

3. In combination with a fabric comprising elastic warp threads and weft threads forming loops, spaced apart by intermediate wefts, at the selvage of the fabric, a plurality of lace forming threads extending along the selvage of the fabric, one of said latter threadsbeing passed over a weft loop and under an adjacent weft loop, another of said'threads being passed under said first weft loop and over said adjacent weft loop and a third of said lace threads passing through the weft loops and effective to bind said first two lace threads at spaced intervals into the selvage of the fabric as the weft thread is placed under regulartension.

4; A woven fabric embodying an elastic warp and a weft arranged to form loops at the selvage of the fabric and having an ornamental edge formed of a plurality of warp threads, the inner two of said warp threads being woven over and under the weft loops and a third warp thread being bound into the selvage by spaced weft loops and in turn binding said first mentioned threadsin theyfabric.

5. A fabric comprising elastic warp threads, and weft threads forming loops, spaced apart by intermediate wefts at the edge of the fabric, a plurality of lace forming threads extending along the edge of the fabric, one of said latter threads being passed over a weft loop and under an adjacent weft loop, another of said threads being passed under said first weft loop and over said adjacent weft loop and crossing said first lace thread, and a third of said lace threads. passing through both weft loops outside of said first threads, and effective to bind said crossed lace threads at spaced intervals into the fabric as the weft threads are placed under regular tension.

6. A woven fabric embodying an elastic warp and a weft extending back and forth to provide return loops and having at one.

edge an ornamental lace effectxformed of a plurality of threads, theinneritwo of said lace threads being woven over and under the weft and the third thread being bound into the fabric byspaced weft loops and in turn binding said first mentioned lace threads into the fabric. v I g 7. In a woven elastic fabric, an orna-' irnental lace effect along an edge of the fabric formed by warp threads extending along said edge, an outerone of which is secured in cross engaging relation to adjacent warp threads by wefts, to the edge at intervals spaced apart by at least oneweft, and effective to secure the remainder of said threads to the fabric, thereby to provide lace forming loops when thefabric is under nonfmal contraction. V

8. A woven elastic fabric embodying a warp and a weft and having at an edge an ornamental lace effect formed by warp threads, an outer one of which is secured in cross engaging relation to, adjacent'warp threads by wefts, to the 'selvage at intervals spaced apart by at least one weft, and effective to secure the remainder of said threads to the fabric thereby to form warp loops whenthe fabric is under normal contraction.

9. A woven elastic fabric embodying a warp, and a weft extending back and forth to provide return loops, and having at an edge an ornamental lace effect formed by warp threads, an outerone offlwhich is secured in cross engaging relation to adjacent warp threads by wefts, to the selvage by weft loops at spaced intervals separated by intermediate wefts and effective to secure the remainder of said warp threads to the fabric, thereby to form warp loops when the fabric is under normal contraction;

10. The method of weaving an elastic fabric which comprises forming weft loops valong an edge of the fabric and securing warp threads in cross engaging relation to eachother along said. edge intojthe selvage of the fabric at intervals by weft loops spaced apart at least one weft while said fabric is under tension, and releasinglsaid fabric from tension, thereby forming -an ornamental edge consisting of Warp loops.

11. The method of weaving an elastic fabric which comprises forming weft loops along an edge of the fabric, laying Warp threads over and under weft loops spaced apart by intermediate Wefts While said fabric is under tension, and securing said Warp threads at said spaced loops by laying an additional warp thread through said loops and releasing said fabric from tension, thereby formlng an ornamental edge consisting of Warp loops.

In testimony whereof I aflix my signature.
