In carrying yout -this invention, narrow, flat,

Vribbon-like.stripsorstrands 12 and '13 are i' f formed by braiding hempof anysuitablei quality or` grade, ror; similar "relatively'fsti' 90 i l v tion of the crinkled weft material. The narrow, ribbon-like braided hempstrands 12 and 13 are then arranged warp-wise on suitable flat warp knitting` machines,`of the general character illustrated and referred to in the Patent No. 1,618,766,

herein above mentioned.

A Yseries of parallel chains of knitted stitches 14, 15 and 16 are then formed of correspond-.ingl warp threads on said knitting machine, parallel `to said braided hemp strands and disposed adjacent the edges thereof as indicated in Figures 1 to 5 inclusive. The longitudinally disposed chains of knitted stitches 14, 15 and 16 are preferably formed of artificialV or synthetic cellulose threads, such as the so-called visca threads, or so-called artificial straw threads.

With the formation of these successive stitches or links of the longitudinal or warp chains 14, 15 and 16, transverse or weft-like threads or strands 17 and 18 are extended back and forth across the wi `th of the fabric on the back and on the face thereof, respectively, and are interlaced with the successive stitches or links of theV series of longitudinal or warp-like knitted chains 14, 15V and 16. thereby7 to tie together the series of knitted chains 14, 15 and Y16, and the braided hemp filler strips 12 and 18 disposed therebetween.

The back weft threads 17 may be any suitable, relatively stiff material, as for instance plain visca or artificial straw threads. 2 rThe face weft strands 18 on the other hand of a composite nature illustrated on a much enlarged scale in Figure 6. Thus the facev weft strands are of the general character disclosed in the Lipper Patent No. 1,661,142, of February 28, 1928, comprising' a taut core strand 19 of cotton or the like, relatively stiff and ribbon-like body strands 20 ofV artificial cellulose, such as artilicial straw, wrapped loosely around said core strand 19 in a generally spiral formation and a relatively thin binder strand 21 wrapped more tightly around said core strand and said bony strands 19y and 2O respectively to bind thev latter to the former at intervals The composite strand 18 thus formed is of a generally loose,` Y

bulky and crinkled character, and when interlaced with the knitted chains 14, 15 and 16, serves the dual Vfunction of a surfacingv material in relation to the braided hemp filler strands 12 and 16, and as aspacing means for said knittedchains 14, 15and 16, since the generally rough or crinkled character of the weft Vstrand 18 causes an interlockinrgbetween said crinkledV weft thread 18 and the series of knitted chains 14, 15 and 16, which prevents the latterfrom slipping to and fro upon the wefts 17 and 18 and from varying its spaced relation. This latter-function of the surface weft strands 18 is like :the functhreads in the textile fabric of the Lipper Patent No. 1,618,763.

.The straight visca or artificial straw weft threads 17 on the back of the instant novel fabric, in turn serve to impart transverse rigidity 'or stiffness to the fabric, since these transverse weft threads 17 are relatively stiff or rigid and extend substantially straight l across the fabric. 1f desired, the straight and trated, in which, like in the embodiment illustrated in Figures 1 to 6 inclusive, a plurality of parallel braided hemp or filler strands 23, 24 and 25 are extended through the fabric longitudinally by feeding the braided hemp strands through the knitting machine warpwise. Aln this particular embodiment of the invention however, instead of uniting the series of parallel longitudinal braided hemp strands 23, 24, and 25, into the single unitary narrow fabric, by means of a series of noninterlacing rows of warp-wise knitted chain stitches and separate weft threads extended transversely of the fabric and interlaced with the separate rows of chain stitches ;-the` braided hemp strands are here united intoa unitary fabric structure merely by a series of generally warp-wise or longitudinally. knit- .ted chain stitches of an interlacing character.

Thus, in this particular embodiment of the invention no'distinct weft threads are employed to unite the braided hemp strands or to encasethe same, but instead, thesuccessive rows of warp-wise knitted chain stitches interlace with each other on the face and on the back of the finished fabric, so as to encase the braided hemp strands. f

Thus, in forming this modified narrow fabric according to this invention. the warp threads of which the chains 26, 27, 28 and 29 are formed, are shifted back and forth between adjacent needles ofthe knitting machine, on the face and on theback of the hemp strands 23, 24 and 25, so as to cause the rows of knitted chain stitches to interlace with each other 'on the face and-on the back of the finished fabric, by means of the connecting links 30. By this means the plurality of braided hemp strands 23, 24 and 25 are likewise united into a single unitary fabric'of the narrow type usually referred to as hat braid.

lAccording to the present invention a narrow fabric or hat braid isformed of a plurality of narrower ribbon-like braided hemp strands united into ai single unitary fabric structure by means of an exterior casing formed either of a combination of non-inter- Vlacingrows of warp-wise knitted. chain "igsevgfiag r'iffand connected interlacinglinks.

In Veither event alcornparatively rigid and stiff, narrow fabric'orhat braid is formed which 'readily adapts itself y Patent, is

to the formation of hats by the conventional i methods commonly employed.

I therefore desire the present l embodiments to be consideredrin all respects Y as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.
