ELASTIC WEBBING.

This invention relates to elastic webbing,

primarily but not necessarily intended for use in wide 'WfibSfOI the manufacture of corsets, girdlesand the like.

One of the main. objects is to provide a wide elastic web suitable for corset manufacture and for being cut up into various the exterior of the corset, a soft inner face.

suitable for the inner surface of the corset, and combining with these charactersitics maximum flexibility, strength and porosity to air for purposes of ventilation.

Another object is to provide an, elastic web having the ornamental reticulated outer face, and the soft inner face in which the component parts are strongly bound together, and which can be securely sewed through its body to the part to which it'is to be attached. To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described 'and claimed. I

In the accompanying drawings:

Fig. 1 is a greatly enlarged somewhat diagrammatic outer face view of a web constructed in accordance with this invention;

Fig. 2 is an edge view looking from the left of Fig. 1, and I Fig. 3 is an edge view looking from the bottom of Fig. 1. i I

In the practice of my invention, I prefer to use a single layer ofcoveredelastic cords forming a part of the warp. These elastic cords form the longitudinal sides of a multiplicity of retangles or reticules, made up into a large number of identical patterns. In the particular form shown, there are nine reticules ina pattern, and Fig. 1 shows one complete pattern unit with an extra elastic Warp cord at one side, and an extra filling pick at one end. y

, Tlhe drawing shows four covered rubber warps, 1, 5, 9 and 1 arranged in the same plane in a single layer. Between the lefthand pair of elastic cords (Fig. 1) are illustrated three textile binder warps 2, 3, 1, respectively, constituting in this casethe only textile warps between the covered rubber cords 1, 5. Between the cords 5 and 9 similar textile warps 6, 7, 8, are interposed,

and between the cords 9and 1 textile warps illustrated in Fig. l.

to the pick 13 in theirarrangement.

10, 11. and 12 are located, this particular instance, the reticules are formed byrun ning a pair of filling picks A, B, acrossthe warps at the lower end of the pattern, and

similar pairs of filling picks E, F and I, J,

above the picks A, B, at theproper intervals. The filling pick AA at the top belongs properly to thepattern next above, as It will be observed that each reticule is formed at the top/and bottom respectively, bytwoparallel filling picks, which in practicelie close together, the sides of the reticules being formed by the elastic cords. These reticules are filled or stuffed by meansof other. filling picks exposed forthe greater part of their lengths on the back or inner surface of the web, as hereinafter described. Two filling picks C, 1) cross the reticules between the fillers E, B; and the filling picks H, Grand K, L, are similarly arranged with reference to their respective reticules; The .picks A,B, E, F,

The filling.

under all of the textile warps. The pick B on the otherv hand passes under all ofthe elastic cords and overv all of the textile warps. The filler picks E, I are similar to pick A, and the filler picks F, J are similar back fillers which present the soft back surface, are located for the main portion of their length at the back ofthe web, and only at rare intervals go up into the Web body to pass over a binder. Preferably they pass over and are held by textile warps only, being located beneath all of the elastic cords, as shown, but I do not limit myselfin all aspects of the invention to this particular I ternunit. The back filler pick G is held only The by the warp 7, so as to be caught and held at a point offset from the holding points of thcpicks G, D, and thcback filler pick L is also caught and held by the warp 7.

-T l i e back filler pick K is held by the binder warp 3, and thebaok filler pick H by the binder warp 11.

For the elastic cords, I preferably use single threads of 34 rubber, covered with two layers of cotton yarn. The rubber threads are covered while under moderate tension and are held in tension by the covering, that when the web is cut these'elastic cords do not draw up and distort the fabric. "When these elastic cords are removed from a piece of web they will ')referably beef substantially the same length as the piece ofweb from which they were removed. This obviates the use of much or any sizing inorder to make the web lie fiat, which sizing would have a tendency to reduce the softness of the web. It is preferable in a web of this character to have a minimum a'ndount of sizing. The binder picks are preferably arranged in pairs, as above stated, although not necessarily so in all cases. The textile warps, which are all binders, may be conveniently formed of two threads of 26 hard twisted cotton yarn, twisted together to make up a so-called 262 warpyarn. Each binder filling pick'is preferably formed of two threads 0f19/2 soft twisted yarn, delivered together by the shuttle to constitute one pick, these threads being woven substantially parallel to each other. Twisting together of these threads may occur to a certain extent as an incident of manufacture, but the intention is to have them substantially parallel. The binder filling picks have sufiicient strength and at the same time considerable bulk, and the individual binder picks will bepcreferably about three times as bulky'as the respective textile warps. The back filling picks used for creating the soft back surface are, on the other hand, preferably bulkier than the binder filling picks. In the particular case illustrated, the picks'C, D etc., which pass through the centers of the reticules,.are each made up of three threads of 19/2 soft twisted yarn, these; threads being delivered together by. the shuttle as one pick in a single traverse of the shuttle and woven in substantially parallel relation. Thuspin this instance, the back filling picks C, D, etc. are each about 50% bulkier than the respective binder filling picks A, B, etc., and are approximately four and one-half times as bulky as the textile war s 2, 3, 4, etc. Due to this fact and the met 10d of holding the back filling picks in the web, they present a back web surface of a soft velvety character, notwithstanding theuse of the elastic cords and the relatively thin and hard textile warps. Owing tothe fact also that the filling picks C, D, etc, and

also preferably the picks A, B, etc., are each constituted bysubstantially parallel threads,

the web is given addcd'flexlbility. The arrangement of the back filling in the centers of the reticules is also such; as to inake the reticule centers porous, thus providing proper ventilation.

In the operation of forming the web, one of the loom shuttles weaves two picks of a filling of one character, e. g., binder filling, and the second shuttle weaves two picks of another character, "e. g., back'filling. This sequence isthenrepeated indefinitely. The binder filling, as above stated, produces cross ribs in the web and also has ash-011g binding effect. The back filling not only provides a soft back on the web buthas, in addition, a certain spacing efiect. The web may have a selvagc of any suitable cl'iaracter.

The web of my invention has a warp in which all the threads are strong; The back filling picks should obviously be woven into the web with very little. tension so as to increase the softness of the inner face of the web. Tlnsalso increases the pm-osu y of the central parts of the reticules formed by the elastic cords in combination with the dense cross ribs. The cotton. covering of the rubber cord is preferably such that the cross section of the'cord is about three tiines'that of the rubber inside, which is usually about nd of and inch square. The twist in the individual threads of yarn used in the filling should be considerably less thanthat of the twist in the individualthreads of the textile warps.

While in'the preferred form each pattern unit contains three covered rubber warp cords, nine binder warp threads, six binder filling picks, and six back filling picks, it will be understood that these numbers, the sizes of the threads, and the arrangement thereof, are susceptible of considerable variation within the scope of the invention, and various other changes may be made in" the details without departing from the principles of the invention as defined n the claims.
