ELASTI C WOVEN FABRIC Filed April 25, 1929 `Patented Apr. 22, 1930 COMPANY, oF wns'rnmnz,V RHODE ISLAND, A, conronn'frroiv onv nnonn' isnAnn f :ELnsfrrc wovnnrnnarc Application Vfiled April v25,

The invention consists in elastic woven fabi f ric embodying certain principlesof fabricconstruction by which important advantageous results are attained.y

Fig. V1 of the drawings lillustrates in an opened-out state, ywith the component warp" and weft elements spread apart from oneanother, a portion of webbing embodying the invention.

Fig. 2 is a view on lengthwise of the .warp threads inthe plane indicated by line 2,2, in Fig. 1, showing a rubbers-warp and three binder warps but with gure warp threads omitted in order to illus- .trate more clearly certain features to which reference is made later herein.

Figs. 3 and 4 are views 'in section 1n the planes which are indicated by lines 3, 3, and V4, 4,l respectively in Fig-1, with the binder warps omitted. s

v The :illustrated fabric is composed of figure warp threads'l,'1, binder warp threads 2a, 2b, 2c, covered vrubber warp cords v8, 3,L

' v andpicks 4, 4, of weft.` The successivel picks of weft lie alternately above and below the rubber cords, in two weft planes. The rubber cordsextendstraight between the two planes. s The figure warp threads, as indicated in Figs.

Sand 4,'vappear at the'opposite faces, alternately, of the fabric,according to there- .quirements o-f the effects sought to be attained,

and form longer or shorter iioats atV the respective facesaccording tothe'features of the design incorporated in the fabric. The iigurewarp threads are employed singly, with a r binder separating each figure thread from those adjoining, so as to give the figure the most even distribution possible on the face l and the back of the fabric.

.'Having reference more particularly to Fig. 2,k as will be seen therein, the binder warp always moves with the rubber., never in the caused by running a'binder againstthe rubthe lorder of a section rubber.

ber, either whengoing up, or down, or both,l which is the usual method. With the binderlworkingl always with the rubber, it is possible to run it very tight, and it will not have the usual tendency to make Vthe upper and lower f f picks of filling cut into the covered rubber every time the webbing is stretched. Such tendency of the binder to press the lling into Y the rubber warp lalways occurs where the binder is run against the rubber, and after frequent stretching of a fabric in which such is the case the rubber cords will break at these places.

Changingthe binder always with the rub-kv ber allows the binder to lie in a position when weaving nearer to the straight position that the vrubber takes when weaving than would be the case if the binder worked `against the In other words,`more of anobtuse langle is formed where the binder thread bends down or up. Therefore, as well asthe binder not having a tendency to cut the filling into the rubber, thebinder will reach the limit and thus-put a limit on the strain to which l-`t-he rubber is subjected sooner than would-be the case if the binder Vworked against the rubber, either going up or going down, which lis the common practice when making elastic fabrics. v Y

The figure warp is run slacker than the binder warp, as indicated in Figs. 3 and 4,

namely one having more than usual warp ends y"and weft picks per square inch. The fabric thereby, also, is rendered stronger by reason of Vcontaining more ends to resisty strain longitudinally.
