MACHINE-BRAIDED LACE INSERTION AND METHOD OF MAKING THE SAME.

Application filed' April 9, 1926, Serial No separate insertions. Hitherto however'the process consisted in forming the entire lace of insertions, directly abutting one-another with their edges running either at right angles to thelongitudinal direction of the lace or in a diagonal direction. In consequence of this there can be produced, according 'to the known process, only insertions having straight edges, namely either rectangular or square insertions. A further drawback of the known process is that the insertions formed by cutting up the continuous lace do not possess firm edges andconsequently they readily tray out at the edges. V

The subject-matter of the present invention is a process of producing machinebraided lace insertions-for table covers or centres, curtains. and similar articles which obviates the above-described drawbacks and enables lace insertions to be produced which may possess'not only. straight, but also con? vex, wavy orZig-za'g edges and thus patterns of desired contour and at the same time are bounded by firm edges which are not liable to fray out.- i

. According to the newprocess theinsertions are produced as portions of a continuous lace with parallel longitudinal edges by those threads not at intervals employed for the insertions being led out of the latter and braided into a. groundwork wholly or partly surrounding the insertions and supporting the edges of the latter, while at the same time some of the threads employed in the insertions are returned at the edges of the insertions in such a mannerthat firm edges are formed there. The insertions so produced in the form of a continuous lace are then liberated by cutting away the groundwork surrounding them.

Two examples of the manufacture of a lace produced according to the new process and containing the insertions are illustrated in the accompanying drawings wherein. Fig. 1 shows a piece of lace according to the'first example,

Fig. 2 a fragment of this lace on amuch enlarged scale and 100,792, and in Germany October 6, 1925.

Fig. 3 a piece of lace according to the second example. a

Referring to the drawings, the lace insertions at, a shown in Figs. 1 and 2, which are entire'or complete in themselves, clearly constitute portions of a continuous lace with parallel longitudinal edges. This lace contains such a number of braiding threads as is necessary for thatportion of the insertion which has the'greatest'width. Thelace is produced on the braiding machine by'the braiding threads being braided togetherin' i the manner determined by' the desired pattern of the insertions a, a; The threads which at timesare-not' required in conse-' quence of the changing width of the inser tions from place to place are led out ofth-e ground face of the insertions and braided into a simple net groundwork?) surroundi ing the insertions which groundwork supports the edges of the insertions a while on its part it is guide d at its parallel longi- This can be effected in the tudinal' edges. usual manner either by the longitudinal edges of' the lace produced on a mandrel I being connected together by auxiliarythreads or by the longitudinal edges of-the' lace being guided on wires;

Those threads, or at least some of them,

which are at times not required forthe pro, duction of the insertions are,lbefore-thei'r egress from the insertions a, so braided with threads remaining in the latter, that the edge portions of the insertions cannot be displaced relatively to the threads which are led outwardly. According to the drawing this is attained by the threads 0, before they leave the insertions, being worked for a greater or 'less'length as warp threads into the ribbon-like selvage border strips 'cZ' pro vided at the-edges of the insertions a (Fig.

2). however, said threads are replaced by threads which are led from the interior of the insertions .into the selvage strips.

' Of the threads remaining at times in the On their egress from the insertions;

threads led out of the insertions. In the are the weft threads f of the ribbon-like strips d provided at the edges of the insertions, which weft-threads coming from: the interior of an insertion, for a greater or less 1 drawing the returning edge-forming threads length runsinuously to-and-fro and then return into the interior of the insertion.

Obviously in the case of a different pattern for the insertions other desired braiding threads may return at the edges of the in sertions for the purpose of forming firm edges, and so also may the threads led out of the insertions be firmly bound together in a manner different from that shown.

The continuous lace comprising a desired number of insertions a, a arranged in succession and simple groundwork portions 6 surrounding them is cutyup into separate insertions aften leaving the machine. This is. effected by the groundwork portions 6, b

which serveonly as auxiliary means for producing the insertions in the form ofa continuous lace, being cutawayat the edges of the insertions a, a (-see'Figs. l and 2, below). In this way lace insertions complete inithemselves andhaving-firm edges not liable to fray outare obtained. It is obvious that by the new process the lace insertions, since they are ,worked no longer with their edges. directly abutting but into a simple severable groundwork, may have arched or conve x.

edges as desired and therefore any desired contour, in particular a rounded or sinuous lZVhen lace insertions of specially large width are to be produced, that is, such insertions as contain at their widest )laces more threads than the machine at ispos'al for the manufacture possesses bobbins, then there are produced, instead of complete sertions, only part-insertions, for instance,

half-insertions in the form of a continuous lace. I The parts are thenconnected together iiltorcompllete insertions after they have been separated from the groundwork of the lace.

An example of this lace is shown in Fig. 3, wherein a a are the half-insertions of the lace, which, in thesaine manner as above describedwi'th reference to Figs. 1 and 2,

are reduced in the form of a "continuous lace the threads at times not required for the insertions being ledont of the ground faces of the insertionsa and being braided tim simple groundwork. In thiscase the groundwork portions b are arranged at only oneside of the half infsertions, so forming merely a longitudinal edge of thelace, while the other longiti'idinal edge "is formed by the rectilineal inner edge {of the half-insertions a The firm edges at the boundaries of the insertions are formed, and the edge-portions secured against displacement relatively to the braiding threads led out of the insertions, in the same manner as in the example according to Figs. land 2. g r 1 After finishing the lace the half-insertions a are liberated by cutting away the groundwork portions 1) (see Fig. 1, left and bottom) and then, as indicated by the representation in Fig. 3 of a completely severed halfinsertion a each two correspondinghalfdn sertions are placed with their straight inner edges abutting and are securely joined together by sewing or in similar manner.

Obviously instead of half-insertions, "0 smaller fractional insertions may be ,prodnc'ed in the form of continuous webs of lace and after being cut out may be placed together to form complete insertions: for example,the insertionsmight be divided into three or four portions, namely one or two middle portions and two side portions, the a middle portions and side portions being in each case produced in the form of a separate web of lace; h i

Thenew braidedlace insertions are ad vantageously produced on the braiding machine of the Malhe're type which operates with one bobbin per late of the braiding track, but they may e produced on some other braiding machine, for instance, on the so-called two thread machine, or machine operating withtwo bobbins per plate. The insertions may belseparated from the con tinuous lace directly after completion of the lace in the factory. The cutting out may however be relegated to the purchaser or. user and, to this end, the intermediate product consistingof the continuous lace containing the insertions be put on the market. a r What I claim is h t k a 1. A continuous flat braided motif bearin v lacehaving parallel longitudinal edges and comprising a series of motivesand a ground- 100 work surrounding the motives and from V which the motives are adapted to be marginally severed, each motif ,includin a body and an edging, some of the threads of the body of each-frnotif bein common to the body and groundwork and ez'rtendingthere between across the mo-tifedging anfd braided with the threads of the latter, and some of the threads of the motif body extending to and beingibraided with the threads of the edging and then returned to the body, said threads" reinforcing the motif edging and forming a firm selvaged edging structure from which the groundwork may be severed without impairing the integrity off the threads "of the edging. i a

2. The herein-described method of producing 1nachine-braided motives or late insertions ofthefchara'cter set forth, which consists braiding a continuous flat lace with parallel longitudinal edges and consisting of a series of motives, each composed of a body and an edging and a net groundwork connecting and carrying the seriesof motives,

' extending the surplusthreads from the nar- 12 5 anderingly extending others ofth'eth'reads 13o from each motif body into the motif edging and braiding the same With the threads of the edging and then returning the body threads back to the motif body, whereby the threads so braided with each motif edging Will form a firm selvaged edging capable of being severed from the ground Work without impairing its integrity, and then cutting away the groundwork surrounding the motives.

3. A machine-braided motif lace accord ing to claim 1, characterized in that the threads leading to and from the motif edging and braided With the threads of the edging are looped about the threads of the edging.

4:. A machine-braided motif lace according to claim 1, characterized in that the threads leading to and from the motif edging are sinuously braided With the threads of the edging.

5. A machine-braided motif lace according to claim 1, characterized in that the threads leading to and from the motif edging are both looped about and sinuously braided With the threads of the edging.

In testimony whereof I affix my signature.
