To all whom t may concern,.-

Be it known that l, Enom; lijnen, a subject of the Emperor of Germany, and resident of Langerield, near Barmen, Rhenish Prussia, Germany, have' invented anew and uselul Process for the Manufacture ot i Lace with a Grauzelike Ground (for which l have tiled applications for patent in IGiermany d an. 9, 1915, Patent No. 294217, and March 5, 1915, Patent No. 295161; Switzer-l land Nov. 1,1915, atent No. V72814:; Austria Nov. 2, 1915, Patent No. 13814:; Sweden Nov. 3, 1915, Patent No. l11390; Netherlands Nov. 8, 1915, Patentltlo. 2783; Belgium Nov. 8, 1915, Patent No. 270629; France Nov. y13, 1915, Patent No. 512098; `pllngland J an. 7, 1916, latent No. 100015; ltaly April .10,` 1916, latent No. 153776;`Spain April 26, 1916,1'atent No. 62162) of which thelollowing is a full, clear, and exactspeciiication, such as will enable others skilled in the art of this manufacture tomalre and use the same. y Laces with a gauze-like ground are already known, and these have beenmanufactured .on single-thread braiding machines (i. e. inachines with one bobbin per plate)` in such a` manner that the braiding threads are braided together in groups` into the several nar row strips which run longitudinally and form the warp or chain, and'these; strips are connected at certain places to form transverse weft strips by exchanging the marginal threads ofeach two adjacent longitudinal strips. These laces have come into the market hitherto almost exclusively as so-called insertions, that is, with straight edges. c 4

rlhe subject-matter of the present invention is a new process for manufacturing such bobbin-made lace with a gauze-like ground Von single-thread braiding machines, which process makes it `possible to produce pretty and permanent scalloped or serrated formations. This process consists in the following..

During the manufacture-of the lace on the single-thread braiding machine one or more retaining threads arev worked into the lace in such amannerthat these threads arebraided, in accordance with the forni oi the serrations or scallops to be produced, alternately in a longitudinal strip and in a 1ere. semi ne. riante'.

transverse strip, and then the lace is out out along the retaining threads. lin this is obtained a lace with an edge having serrated or scallopedl formations, which edge owing' to said retaining threads, which run the entire length of the web and therefore always lie along the edge, is entirely protected against iraying out, notwithstanding that some of the bnobbin-threads have been cut through. Perishing of this lace through use and in washing is not theretore 'to be reared. The serrated and scalloped formations however have exactlythe same style as the remainder oft the web, that is, like the latter they are part of the lace :format-ion.

It more et such retaining threads are introduced' into the fabric then the same are disposed in the weft and warp strips and not only interlaced with the ordinary bobbin strands but also with each other in order t0 increase the durability of the margin.

ln manufacturing narrow laces, two are preferably produced simultaneously on the lace machine in such manner that the same are. braided with their serrated or scalloped formations engaging one another, there belng then of course for each lace a thread worked in therewith in the above-described manner. rlhis entirely avoids waste when the lace is cut out. The invention further consists in the lace produced as above.

Two examples of a lace'manuiactured according to my invention are illustrated in the accompanying drawings, wherein show Fig. 1 is a plan view of the lace fabric with the two parts united,

Fig. 2 shows the saine after cutting to torni two serrated parts,

Fig. 8 is a detail of the structure shown in Fig. 1, on an enlarged scale,

4;- is a plan view of a lace produced in a somewhat modied process,

Fig. 5 is a detail of the lace shown in F 1, on an enlarged scale.

Referring to the drawing, Figures 1 3 show the edge of the lace is secured by means of one special retaining thread. in this en ample the longitudinal or warp strips a of the gauze-like lace each consist oft tour sol threads 1, 2, 3, 4 braided together, and the transverse strips b are formed owing to the exchange at certain places oi the marginal threads of two adjacent longitudinal strips a. A pattern may be produced by an accumulation oit transverse strips, i. e. by till ing inthe various squares by a more irequent exchange or' the braiding threads. The web shown in Figs. 1 and 3 for manufacture on a single-thread braiding machine forms indeed an intermediate product 'for obtaining the two laces. Accordingly, the two retainingfthreads c and ai are worked into this intermediate product, the manner ot interworhing .being clearly shown inFig. 3'.l These threads lengage at one time the l(,)Iigitndinalr strips d., and then they pass with Vthe transverse strips to the next longitudinalstrips. By `cutting through the.

intermediate product shown in Figs. 1 and 3 between the two retaining threads, i. e. alo-ng the `dotted line .4i-B, the two iinished laces shown'in Fig are obtained. ln these the specially incorporated threadsc, d run along the edge which is here oi Vserratedl tor-mation. These threads are at no place severed, andl everywhere give the serrations a-secure hold, and so with certainty prevent thev said edge from being frayed out or unravel'led. irtheexample those squares or rectangles of the gauze like lace which are located alongside the serrated edgeare filled This is however notv at all necessary. rlhese portions may remain open if desired. Moreover in the present case the longitudinal strips (L consist wholly of tour braiding threads and the threads c and d are'specially y inserted. y

In Figs. 4 and 5 is disclosedl a modified method of my invention according to which l again employ the tour braiding threads 1, 2, 3 and 4C as shown in order to constitute the longitudinal or warp strips e, the transverse strips f being formed as before described by exchanging the marginal strands of two adjacent strips e. Beside in the said 'fabric are interwoven soine other threads g running in zig-zag form as shown and being partly connected with the longitudinal strips e and partly with the horizontal or weft strands 7?, so that the ground ot the fabric has an appearance of the so called, fillet antique.7

To secure the serrated margin against fraying l have worked in the lace during its manufacture on the single thread braiding machine the four threads It, vl, 7c, Z in a manner that they are introduced in :i marginal longitudinal strip c, then made into a weit strip f where they interlace with the strands g and then worked again into the next adjacent warp strip` c. As will be clearly understood :from Figure 5 the threads L, i, is, Z are braided with each other and with the ordinary bobbin threads 1, 2, 3, 4:.

The fabric is also in this example cut out along the retaining threads, the braiding threads which are cut ed being so strongly interwoven that fraying out is entirely avoided. 0f course, in the exampleshown r in Figs. 4 and 5 also two laces may be manutactured simultaneously in a similar manner as described in `connectionwith Figs. 1 to 3.

0n using a plurality of retaining threads tor each lace, las in Figs; 4 and i5",v prefer `1-.
