This invention relates to the manufacture of woven fabrics and particularly to woven fabrics in which reinforcing or stiffening cords of substantial thickness are laid to provide the fabric with a required degree of stiffness.

A particular object of this invention is to provide an improved cord stiffened fabric in which stiifening cords extend in a weft-wise direction between top and bottom warps and are covered by face and back plies woven to provide a continuous smooth andat'backng and individual stiffening cord facings which are locked to the backing in fixed positions on either side of the stiffening cords.

Another object is to provide a novel method of weaving a stiifened fabric in which certain of the warps are woven to form individual face plies about a series of stiffening cords and certain other warps are woven to form a backing with binders which serve to mould each individual face ply about a stiffening cord and to lock the Vmoulded face ply in a fixed position relative to the backing.

Proceeding now to a more detailed description, reference will be had to the accompanying drawings, in which- Fig. 1 is a plan view of an improved stiifened fabric made in accordance with this invention.

Fig. 2 is a plan view illustrating the sequence in which a series of weft threads are interwoven with a series of warp threads.

Fig. 3 is a perspective view of a section of the fabric, showing the fabric loosely woven to more clearly illustrate the nature of the weave.

Fig. 4 is a diagrammatic view illustrating the `manner in which the first of a series of warps is woven with certain of a series of wefts to form the face ply.

Fig. 5 is a view showing the second face ply warp of the series in relation to the wefts.

Fig. 6 is a view showing the first back ply warp of the series in relation to th-e wefts.

Fig. 7 is a view showing the third face ply warp of the series in relation to the wefts.

Fig. 8 is a view showing the fourth face ply warp of the series in relation to the wefts.

Fig. 9 is a view showing the second back ply warp of the series in relation to the wefts.

Referring more particularly to the drawings, the fabric appearing in Fig. l is a stiffened woven fabric including a back ply which forms a substantially flattened back covering of weft-wise stiifening cords and a plurality of woven face plies forming individual coverings for the stiffening cords, said individual coverings being 4 claims. (o1. 13essii bound to the back ply'at either side ofthe stiffenn ing cords rand locked in place in the manner hereinafter described.

'As' will be seen in Fig. 2, the warp threads are 6, 1,.`8 and 9, of-which, 5,1 and 8 are utilized in forming the individual face plies and are hereinafter termed the top warpsand 6 and 9' are utilizedinforming the back ply and are hereinafter termed the bottom warps. A series of weft threads B, C, D, E, F, G,.H and J are interwoven with vthe warps in the above sequence, followed by itheuweft-wise laying of a stiffening cord X lloetween'the top and bottom warps prior to the interweaving. of each successive series.

Fig. 2 is intended only to illustrate the order Ycr pattern .of the weave. The manner in which the fabric is woven is more clearly illustrated in Fig. 3. This is further augmented by Figs. 4 to V9 which separately illustrate the contours of each of the warps shown in Fig. 3. Beginning from left to right, the last weft J of the preceding series is passed under and over top warps 4 and 5 overlying bottom warp 6, then under and over top warps 1 and 8 and overlying bottom warp 9. A stiifening cord X, shown in Fig. 2, is then laid between the top and bottom warps. (This cord X is not shown in Fig. 3 for reasons which will become apparent herebelow.) A binder weft B of the succeeding series is then passed under and over bottom warps 6 and 9 overlying the top warps which have become idle. Binder B is then mov-ed to the left to tighten the preceding weave. This is followed by a second binder weft C which is passed over and under warps 6 and 9 and overlying the top warps. Binder C is then pushed to the left to further tighten the weave of the preceding series of woven threads and to lock them in a xed position. The bottom warps are now permitted to li-e idle and a face ply is formed by weaving the remaining wefts D, E, F, G, H and J with the warps 4, 5, 1 and 8 in a 1 and 1 weave. Stiifening cord X is then laid between the top and bottom warps and the binders B and C of the succeeding series are interwoven as previously described and then -pushed to the left to move the stiffening cord'X to a centre position and tighten the face ply 'about the stiifening cord while at the same time pulling the bottom warps taut to provide a flattened back ply. The idle top warps beneath the binders serve to stiien the back ply at the intervals between the stiifening cord pockets formed by the face and back plies.

With this method of weaving, the back ply is arranged ina series of numerical sequences 4, 5, i

substantially smooth and flat throughout the weave of the fabric while each pocket forming face ply is rounded to conform substantially with the contour of the stiffening cord lying on top of the back ply. The binders B and C, after having tightened the woven face ply about the stiffening cord, retain the face ply in this fixed position through their interweave with the bottom warps. It will be seen that the tightening of each woven face ply is against the preceding locked binders s'o that the face ply 'is vactually locked on both sides in its fixed position about the stiffening cord.

Stifening cord X may be of anyisuitable Amajterial including a core with a suitable covering, as illustra-ted, which may be treated'with a. suitable water repellent sizing for 'extra stiffening. As an alternative, the entire woven fabric may be treated with a water Arepellent sizing 't'o `en's'u're permanency of the stiffening qualities of the fabric even vafter 4repeated washin'gs.

I claim:

1. A stiffened woven fabric made of warp threads, weft threads and stiffening cords extending weft-wise `of the fabric .between ycertain of a series of the warps, said.warps being inte'rwoven with the wei-ts 4to `provide a 'continuous back ply for a series of stiffeningico'rds and-.individualface plies `affording .a fa'cing 'for each-stiffening cord on one side of said back ply, .each of said ffacings merging with 'the back ply -at Ao'pposite sides `of the vstiffening cord andv locking means for securing each kfacing at the .pointsof mergence with the backply Acomprising apair of binder threads interwoven with certain Vof Vsaid warps overlying the remaining warps, -said `*binders 'being secured against the woven vface ply to lock the latter vin its fixedposition about the stiffen-ing `cord.

2. A stiifened woven fabric comprising top and bottom warp threads arranged in series of two top between successive bottom warps, a plurality of stiffening cords extending weft-Wise of the fabric between said top and bottom warps and weft threads interwoven with the warps in series to provide a continuous back ply for said stiftening cords and individual facing plies over each stiiening cord on one side of said back ply, each s'eri'es of weft threads including 'at least two binder threads interwoven with said bottom warps to form the back ply and successive weft 'threads interwoven with the top warps to form Aa -facing ply, said facing ply being locked in a vfixed position about said stiiiening cord by the v binders oflits-series on the one side and by the A`bindersoi the succeeding series on the other side.

3. --A'stiffened woven fabric as set forth in claim 2, in which said top warps are passed beneath .the binder threads to reinforce the back ply be- ;tween successive face plies.

4. 'A stiffened wovenfabrie as set'forth'in 'claim y2, said binder threads being interwoven with the bottom warps-in `a 1 and 1 weave.A g
