MANUFACTURE OF STOCKINGS Filed April 28, 1939 Patented Mar 9, 1943 2,313,294 MANUFACTURE OF'STOCKINGS I Jean Garric, Troyes, France; vested in the Alien Property Custodian Application April 28, 1939, Serial No. 270,679

In Luxemburg May 11, 1938 1 Claim.

The invention relates to the manufacture of stockings and other articles or pieces knitted on Cotton frames and other similar machines. and refers to the joining or uniting together, by seams, of articles, of pieces, or of parts of knitted stockings, after having. with this purpose in view, previously rendered nor -raveling the edge of one or of both the pieces, articles or parts of stockings intended to be united and fixed the one to the other, the non-raveling edge, that is. the edge provided with strong or secure loops, thus forming, for the said purpose, a true or secure selvedge.

It is known that, in order to obtain this uniting by seams of the edges of pieces, artic es or of parts of knitted stockings together, and especially in order to obtain, for example, the uniting of the edge of the foot to the heel, during the course of the manufacture of so-called complete or combined stockings, which permits of the elimination of re-looping or re-stitching (a costly operation and one which is, moreover, difiicult in the case of combined stockings made on old fiat knitting machines without divided needlebar), it is necessary to transform into selvedges the usually ravelable edge or edges of the pieces, articles or parts of knitted stockings (such as the commencement of the foot parts) to be joined together by a seam, by making the first row of same non-raveling.

For example, the first row of loops of a knitted piece, especially of a part of a stocking, has been rendered non-raveling, although for a different purpose, by effecting, before the formation of the complete stitches of the said row, the transfer of one loop over two, from one needle over that following its neighbour, all the needles then having one loop or mesh, and one mesh in two being transferred by two needles, by means of a special mechanism replacing or modifying the usual narrowing mechanism and its motion and working before the formation of the loop, which excludes every possibility of renderin non-raveling any row of finished meshes or loops in a piece whil being knitted.

On the other hand, any row whatever of a piece of knitting, especially of a part of a stocking, may be rendered non-raveling, after its formation, by using the known process of the transferring of one mesh or loop over two, from one needle over the following needle, one needle thus having two meshes while its neighbour has none, by means of the usual lace or openwork attachment or narrowing mechanism and the usual transferring motion towards the right, or the left.

Now the rows of non-raveling meshes or loops obtained by these processes give defective selvedges, in the sense that they render it diflicult to form seams, for example by means of a whipstitch machine, because of the fact that the said non-raveling selvedges are jagged and excessively extensible, the result of which is that, after two pieces have been joined or united together by seams, the appearance of the joining line becomes too obvious, forming moreover a sort of openwork line.

The object of the present invention is to obtain, on Cotton frame or other similar machines, a selvedge which does not possess the faults of those obtained up to the present by" the known processes of making non-raveling a row of meshes a of a knitted article, piece or part of a stocking, and, for this purpose, it has as its object a process which consists essentially in rendering nonraveling, after its formation, the whole or part of a row of meshes or loops of a knitted piece, article or part of a stocking, either at the beginning after having knitted one or two rows of meshes intended to be raveled or unroved, or during the course of knitting, after having made anynumber of rows, by the transfer towards the right or towards the left, of one loop over two, from one needle over that following its neighbour, by means of the lace or openwork attachment or narrowing mechanism and of its .normal motion, the transferring motion being controlled however so as to have an amplitude of two needles instead of one only.

The transfer can also be made to the right over one part of *zthe row and to the left over another part, either by operating with two separate parts of lace bars, the one transferring to the right, the other to the left, or by operating with drums, setting on consecutively to the right and to the left, the necessary transferring hooks or needles being moved into action at each of the two movements of the mechanism.

Owing to this process there is obtained a straight, neat, firm selvedge, only slightly extensible, which permits of the easy formation on the machine of fiat and fine seams, and the uniting line with another piece, article or part of a stocking which results therefrom has a full appearance and resembles the joining lines obtained by re-looping or re-stitching, the seam thus obtained being moreover as a rule more solid than the re-loopingseam. In addition, the extensibility of the seam thus obtained can be .regulated, either by modifying the length of the row of meshes or loops intended to 'bezrendered non-traveling (the more this row of meshes is tightened the less extensible will be the selvedge obtained), or by modifying the number 'or the size of the threads of this row of meshes.

In order to make the invention well understood, and by way of example ofits practical application, the process which is the object of the invention may be carried out by means of the lace or openwork or narrowing mechanism, comprising lace or openwork bars or. drums, with transferring needle bar plates, one needle in two being in action, these bars, drums or plates transferring by two needles, to the left for example, in order to give a non-raveling row of loops, which, after separation of the prior rows, will finally give a straightsecure selvedge, of which the phases of the interlacing of the meshes are shown diagrammatically in the accompanying drawing, in which:

Fig. 1 shows the knitting before transferring; the two rows of loops or meshes A and B may be those done either at the very beginning of the knitting or during the course of the knitting after the formation of any number of rows of meshes, these rows being intended to be raveled or cut, one single row being sufficient if necessary.

Fig. 2 shows the diagrammatic trace of the following row of meshes C, which 'is rendered non-raveling after the transferring of one mesh in two by two needles, which transferring changes the shape of the meshes transferred and of those not transferred, as well as the meshes of the preceding row "B, it being understood that this diagrammatic trace shows an excess of length of thread over that necessary inreality.

Fig. '3 shows thefinal interlacing of theimeshes 5 of the non-raveling row C forming the selvedge after knitting of the subsequent rows D of the piece, the two rows A and B having been removed by raveling or cutting.

These rows A and B may moreover be removed after the knitting of the piece; for example, for, stockings, after the bunching up of the sides of the leg for the knitting of the heel (in the case of machines having needle guide bars with fixed centre part) or after the complete knitting of the stocking, before the assembly'of the heels on to the feet (in the case of machineshaving needle guide bars with moving centre part, able to knit the heels after the legs, before knitting the foot). "The drawing 20 shows the straight non-raveling selvedge, and as the wholeof the thread of the loops of the selvedge is necessary for the interlacing of one needle to the other, the result is that thesaid selvedge is neither too jagged nor too long.

I claim:

The method of producing a flat non-raveling selvedge for parts of the sole of stockings on flat knitting frames, comprising completely forming a predetermined number of rows of 30 plain loops, then transferring by means of the usual narrowing machine each second loop of at least a part of a succeeding row to the following second needle, and raveling the first formed rows to exposethe row of transferred loops.
