Description

Method for the production of milanese or other warp-like knitwear on knitting machines, in particular circular knitting machines. - Knitwear without warp threads according to patent specification 741 592 as well as for such goods with bound weft threads.

The improvement relates to a method for passing long thread loops by means of transfer plates, which are placed on the back of the needle in a dial are stored and operated, as well as in, this patent in particular to Figs. 45 to 48 .shown movements of the needles to the transfer blanks.

The process for the production of such goods basically exists -in that between and above all or certain non-adjacent needle stitches existing thread parts are formed into long thread loops so much longer than the 'ordinary needle stitch loops that they use when forming a following Row through the needle stitches of the row with which this long Thread loops are formed, or by the needle stitches of a subsequent course pulled through and in such a following course from the needle that in one of the previous rows has not processed the long thread loops, or on a needle lying to the side with the usual needle stitch of respective row of stitches are formed alone or together with the needle stitch can. This creates warp knit-like weaves, as the cross-weave of the needle stitches of a row of stitches or not only from sinker stitches " Stitch leg parts exist that cross-connect the needle stitches of a row of stitches to the needle stitches of a following row of stitches.

The procedure according to the invention is also suitable for production of knitted goods in which such thread loops do not mesh in a following Row are processed, but tied as a tuck between the meshes will.

The prerequisite for manufacture. such a weft knitted fabric in Warp knitted fabrics as dense and needle-tight knitted fabrics are, d-aß the transfer sinkers for transferring the thread loops to the needles for co-forming stitches one of these Requires appropriate movement and that the needles on the board movements must be coordinated.

These longer loops of thread made for this purpose between two not adjacent needle stitches and over at least one needle stitch are formed, are kept rolling longer over transfer plates and by means of this on the needles for processing in a following row of stitches after the known Method in which needles of a needle group in two successive loop-forming operations To form stitches and loops, the two needle groups are made in two stitch-forming processes formed thread loops of the two partial rows held by two transfer plates, whereby parts of two thread loops lie over a transfer plate, whereby the Disadvantage can occur that parts of bulging thread loops with on needles to which these should not be passed.

To eliminate these disadvantages, it is proposed according to the invention, that each thread loop that is formed in .ein stitch formation process, only over a transfer plate that is moved between the needles to form long loops of thread Kullert held and passed on the needles, so that at the same time the for this procedure uses two groups of needles with two groups of transfer plates work together within two mesh formation processes, so that the transfer sinkers the long loops of thread formed by needles two loop-forming processes each hanging over a sinker before the beginning of the next Stitch formation process so passed on the 'needles that the thread loops of Partial stitch row formed in the last stitch formation process, which follows the needles too locally in front of the thread loops of the first loop formation process, first on the needles of the group that go up from the coulier position, which are the first Partially stitched row has to be passed and then the thread loops of the Partial stitch row of the first stitch formation process on the following, after The top needles of the group that have the last partial row of stitches are passed has formed.

By forming the thread loops of each sub-row on one transfer plate a transfer sinker group enables the thread loops of both partial rows of stitches do not have to be passed to the needles of both groups at once, but rather that the passing of the thread loops of each partial stitch row for itself - that is separated from each other - can be done.

The formation of thread loops also has an effect on this procedure over a plate is advantageous in that these thread loops are essential can be made shorter than is the case if this has two transfer boards lie away. It is also within the scope of the invention to proceed so that after the formation of the two partial rows of stitches is still a normal stitch-forming process to form an ordinary course up to the beginning of the next two partial courses is switched on while the transfer sinkers are not taking up any thread, and that the inventive transfer process of the long thread loops after the normal Stitching process takes place.

According to a further feature of the invention, the procedure can also be that the thread during the formation of the second partial row of stitches over the transfer sinkers and in front of or on the needles of the other group that is in this stitch formation process do not form any stitches, but only go through this stitch-forming process in a higher position, laid and rolled into long loops of thread. This procedure falls the passing of the thread loops of a partial row, so that only the thread loops the first partial stitch row formed after two stitch formation processes Need to become.

Are the thread loops from. two stitches, formation processes after Completion of the same passed to the needles by means of the transfer plates, then is, according to a further feature of the invention, the mode of operation of the transfer boards and needles in such a way that the transfer sinkers of the one group that make the thread loops Wear the last partial row of stitches formed, the same on the one from the ridge height position Pass the needles going up to the group that formed the first row of stitches while the needles of the other group formed the last row of stitches have, for the time being, a short upward movement from the Kulierstellung to open the Execute needle tongues, whereupon the transfer boards of the other group, the the thread loops of the first partial stitch row wear the same on these needles transferred on the upward movement, and after transferring the thread loops the needles of both groups go one after the other to their maximum position in order to reach the Meshes underneath and the thread loops on the open needle tongue bring to.

The method according to the invention relates in particular to production of Milanese-like knitwear, in which the stitches of the partial stitches: row lie on a straight line, that's when two partial rows of stitches make a complete Form course, which is achieved in that the first group of needles the one Partial course and the second group the other partial course of a course, then again the second group of needles, the first partial stitch row and the first group of needles forms the second partial course of the other course, etc.

Two groups of Transfer plates of two different lengths are used, each by itself by means of cam locks be operated.

In the drawing, the methods of the invention are for example shown. There show Fig. I and 3 in a rear view a detail from the needle and sinker row of a circular knitting machine and a looping process Application of the method according to the invention, FIGS. 2 and 4 show a detail in plan view from the row of needles and sinkers on a circular knitting machine and a loop formation process when using the modified method according to the invention, FIGS. 5 to 7 in side view Needle and sinker positions of the method according to the invention, FIG. 8 a needle and blank position of the known method.

These figures are - as far as they are circular knitting machines - For the sake of better symbolization, the top view as well as the associated one Rear view of the sinker and needle row not in the shape of a circle or a circular arc, but shown in a straight line.

In the method according to the invention, the groups of needles in the sequence NI, N2, N2, N1, NJ, N2 etc. carry out one stitch formation process after the other, as a result of which a stitch weave is achieved in which the threads a and b of both partial stitch courses form one stitch complete row of stitches lying on a straight line.

Likewise come. when applying the procedure two groups of transfer boards Pi and P2 in use, each of which has a group of needles work together.

Fi: g. i and 3 show a complete stitch forming process of two partial courses to a complete row of stitches in the direction R. In all needles Ni and N2 (Fig. i) are the long thread loops 3a and 3b of the part rows of stitches from yarn A and B, to be in front of the now beginning new stitch formation process have been passed. The needle Ni picks up the thread a from the thread guide 2 and forms it into ordinary and excessively long thread loops 3, only via the transfer sinkers p1, the free end of which has passed between the row of needles in the direction Z (top view Fig ). In this loop-forming process, the needles Ni, which are located on them and which have already been transferred, are formed with the loops from the thread a together to form two-thread loops. The needles N2 are switched off from this stitch-forming process and do not work the passed thread loops 3b into a stitch, but go through this stitch-forming process with the stitch on the closed tongues of the needles and the thread loops 3b in the hooks in the catch position, and the transfer plates P2 are in place with their free ends pulled out from the same row of needles (as in position Px, Fig. 4), around the thread. a not to be included when kulating the needles N1 (Fig. 2, top view). The newly formed thread loop 3a is not transferred from the transfer plates P1 to the needles @ -. Transfer (Fig. 2), when they move upwards after the weft needle Ni to take up thread for the next weft, which is carried out by the needles N2, because on these needles N2 there are still the previously transferred loops 3b together with the 4/5 stitches. The needles Ni perform a movement N, upwards to open the tongue, before the following: loop formation process, whereupon they then go down again to the height of the comb.

In order to always process only one long thread loop 3 " 3b into the stitch, the long thread loop from the previous wefting process is not transferred to the needles, but the transfer sinkers Pl do not go into the transfer position and hold the thread loops until after the next weeding or drawing process. Stitch-forming process of the needles N2, so that the needles N2 go up in front of the thread loops 3b hanging on these sinkers, but not up to the height of the press-off position so that the thread loops 3b already transferred on them do not come to lie below the open tongue In the stitch-forming process, the needles N2 now process the thread b from the thread guide: 2 to stitches 4/5 and long thread loops 3b only over the transfer sinkers P2, which have passed between the row of needles with their free ends, and at the same time process those on them Needles N2 located loops 3b with to stitches en the transfer sinkers P1 with their free ends, slightly protruding from the row of needles and still holding the thread loops 3 ″ (Fig. 6, transfer sinker position), through this couling process, so that no further thread loop is formed on them from thread b (FIG. 4, top view). The needles N1 maintain their lower position approximately at the height of the comb while the needles N2 are working. After the needles N2 have worked, all of the thread loops 3a and 3b on the needles before the two stitch formation processes have been processed with the newly formed ordinary stitches from threads a and b through the needles Ni and N2 to form stitches in this next row of stitches.

By forming a thread loop over just one transfer plate is the position of the thread loops 3a, 3b so that the same, from the stitches to the respective needles starting from one needle to the other of a group, obliquely afterwards above over the needle of the other group to the support point Pa of the transfer plates, then run almost vertically down to the other stitch.

The thread loops 3b formed by the needles N2 in the previous stitch formation process and the thread loops 3a formed in the previous stitch formation process by the needles Ni, which - as described - have not yet been transferred to the needles, are now before the start of the third stitch formation process (such as the Fig. 3 and 4 show) separately in two transfer processes successively transferred to the needles Ni and N2 before they go up into the squeezing position (Fig. 7, side view). The transfer of the thread loops 3 " 3b takes place according to the invention in such a way that the thread loops 3b of the last partial stitch row formed from thread b, which come to lie after the needles in front of the thread loops 3" of the first partial stitch row formed from thread a (Fig. 4), initially by moving the transfer sinkers P2 into the transfer position R2.1 (corresponding to the top view of FIG. 4 and the side view of FIG. 5) to the needles Ni going up from the coulier position. Meanwhile, the needles N2, which have formed the stitches of the last partial stitch row from thread b, perform a short upward movement to position Ns, (Fig. 3) to open the needle tongues, and only afterwards, when these needles N2 are so far again have gone down so that they are approximately at ridge height, the transfer plates P1 now move from their production to the transfer position P, "and the transfer plates P2 are returned from their transfer position (Fig. 4) to the position according to FIG. 7 , whereupon the needle N2 rises to the top and enters the thread loops 3a that are held there so that the needles are passed over at the same time (FIG. 3, rear view, FIG. 4, top view) be passed ,, it is avoided that a thread loop is passed on two needles, as it can occur in the known method (according to FIG. 8) when two thread loops 3 from one exercise resulting board P can be worn and individual thread loops 3 shift to the side in a bulging manner. (Fig. 8 shows the needles Ni and N2 and transfer sinkers P in the transfer position, seen from the rear.) By transferring the thread loops of the two partial rows of stitches according to the invention, separately from one another, instead of at the same time as in the known method (Fig. 8), these errors can themselves with the intersecting position of the thread loops of the two partial rows of stitches hanging on only one transfer plate do not occur, since here the thread loops formed last, which, as already said, lie after the needles in front of the previously formed thread loops, are first transferred to their respective needles, so that the .fadenschleifen can not hinder and relocate each other when transferring, and also by the successive-up-in-the-transfer position-going of the needles and also by the-successively-in-the-transfer position bringing the thread loops two needles do not get into a thread loop. With this method, the greatest security for the transfer of loops of thread to the needles is achieved.

The above-described transfer process can, however, also only take place after a further loop-forming process, in particular if. After the two partial courses a and b have been formed, an ordinary normal course is to be formed until another two partial courses are formed in between. In this case (according to FIG. 3), viewed in the working direction R, both groups of the transfer sinkers Pl and P2 would not go into the transfer position, but remain until after the end of the following normal loop-forming process - in which they are not allowed to pick up the thread and which loop-forming process of the needles Ni and N2 are carried out together - somewhat pulled out of the row of needles, still holding the thread loops (as in the position of sinkers P., according to FIG. 4).

In this vorbeschri: level mode of operation, during the subscript of the needles type and N2 a weft thread S by means of a weft thread guide F behind the needles are inserted (Fig. 3).

According to a further feature of the invention, however, the thread loops 3b of the last partial stitch row to be formed from thread b can be formed without a transfer movement through the transfer sinkers to the needles Ni immediately before and on these needles during the weeling process of the needles N2. This is done (according to FIGS. 3 and 4) as follows: The needles Nl, which in the previous Kulier- or. Stitch-forming process the already transferred thread loops 3 "located on them have processed into the stitch, move in front of the thread b from the thread guide a so far upwards, as in Fig. 3 dashed position of the needles NI that the same, including the thread b, whereupon they move a little downwards again and go through the couling process of the needle N2 in the approximate height position of the needles Ni x shown in side view, shown in dashed lines, so that these thread loops are already on the open needle tongue and on the transfer sinkers P2 are formed (Fig. 4 and 6, dotted thread loop 3b). In this height position, the needles Ni continue until they are brought up into the squeezing position (according to FIG. 7) in their short up and down movement to open the tongue, whereupon only the thread loop 3a from the partial stitch formed first A row of thread a can be transferred from the transfer sinkers P1. From the press-off position (Fig. 7), in which the stitches 4/5 have been brought onto the needle shaft below the open tongue and the thread loops 3a, 3b from the transfer plates are still on the open tongue, all the needles move out slightly downwards, and then also the transfer sinkers P1 and P2 from the transferred thread loops 3a, 31, and the row of needles (Fig. 4). The needles that are to carry out the next loop-forming process, namely the needles N2, move into the sinker position, as do the transfer sinkers P2, and the thread a is processed repetitively according to the operation described at the beginning, with the only difference that the needles N2 and the Transfer boards P2 the first and the needles Ni and the transfer boards. P1 form the second row of stitches. The other needles _N move in front of the thread guide down into the catch position, with the needle in this position; that the thread loops 3a, 3b in the needle head and in the closed tongue and the stitch 4/5 above the needle head cannot be thrown off, because when these needles are returned the stitches 4/5 again below the tongue on the needle shaft and the thread loops on the then . open tongue to lie. have to come. The needles which are switched off from the subsequent stitch formation process after all thread loops have been transferred to all needles always go through this catch position.

With the method according to the invention it is also possible to determine according to the pattern Transfer sinkers during the roving or stitch formation process in the retracted in Fig.6, dotted position are brought, so that no long loops of thread are formed on them, but the thread, only 'lies over the stitches as a loosely lying thread part.

It is also within the scope of the invention, the inventive To use procedures in conjunction with known procedures.
