Description

Thread turning device for flat edge knitting machines The invention relates to a thread turning device for flat edge knitting machines with two groups stored parallel to the chair needles, selected by a jacquard device Switch boards.

The previously known devices for the production of colored plating Knitting patterns only have a single group of folding sinkers, which are opposite the jacquard card is moved.

Compared to the previously known devices, there is the essential of the invention in that there are two groups of such boards, which both in relation to the map and in relation to one another in a pattern staggered because separate groups are stored parallel to the chair needles and for themselves separately in the folding position of the folding plates now also against each other are arranged so as to be displaceable in a pattern in the longitudinal direction of the machine. The upper Group can be offset opposite the lower group, or the lower group can be moved and the top group left, or both groups can be mutually offset, etc. This is now on a certain wale a needle not just a change of the colors of the stacked folding plates possible with each other, but also any change in the colors of the adjacent or folding plates lying above or below one another can be achieved. While So the previously known devices only switch between two colors enabled a needle, the change according to the present device is a lot more extensive, since the folding plates are offset from one another as desired and as far as desired can be.

Through this in any size and in any mutual direction possible lateral offset of the folding plates, a color change is now possible, which can be used to achieve a wide variety of patterns or the like.

In the drawing, the subject matter of the invention is in one embodiment shown as an example.

Fig. I to 3 show the devices in three different working positions in perspective view. Fig.q. to 8 show the to be achieved according to Fig. i to 3 Color change. Fig. 9 shows an example of after the working positions of Fig. i to 3 model effects achieved.

The two sinker groups are in a known manner in the thread turning device stored. The plates 2 form the lower group, the plates 3 the upper group. The part ei containing the grooves for the folding boards 2 is on the top provided with guides in which a slide 3 carrying the folding plates 22 is stored. The part 21 is again on its side on the bed 23, i. H. in Longitudinal direction of the machine, movable. By moving the Carriages 21 and 22 against each other can in this way the plates 3 opposite the boards 2 are laterally offset.

According to the example, it is assumed that two groups, each with three folding boards are covered with a total of six different colored threads and that these two groups of sinkers in the usual position assigned to the needles 6, 7, 8 (see Fig. 4 to 8) are.

The six colors assumed, for example, are followed by a solid one Line (gray A); line broken with one point (blue B), broken line with two points Line (purple C), broken line with three dots (red D), through long dashes line formed (yellow E) and line formed by short dashes (green F) indicated.

It is assumed that in the left-hand fold-over plate of the lower group 2 (Fig. 4) a gray thread A, in the middle fold-over plate of the lower group a blue thread B, in the right fold-over plate of the lower group a purple thread C, in the left-hand folding plate of the -upper group 3 a red thread D, in the middle Flip-flop of the upper group a yellow thread E and into the right flip-flop of the upper group a green thread F is drawn in, so can, for example, the following Color change can be achieved.

With the position of the two folding sinker groups 2, 3 shown in Fig. I, as Fig. 4 shows, either gray (A) or red (D) on needle 6 and blue (B) on needle 7 or yellow (E) and purple (C) or green (F) on needle 8.

If the carriage 22, i.e. the upper group 3, is shifted by two needle pitches in the direction of arrow d (Fig. 2), then, as Fig. 5 shows, the needle 6 can be gray (A), the needle 7 blue (B), needle 8 is either purple (C) or red (D), needle 9 yellow (E) and needle io green (F). If, on the other hand, the carriage 22, i.e. the upper group, is shifted two needle divisions in the direction of arrow b (Fig. 3), then, as Fig. 6 shows, the needle 4 is red (D), the needle 5 is yellow (E), the Needle 6 is either green (F) or gray (A), needle 7 is blue (B) and needle 8 is purple (C).

If it is assumed according to Fig. 2 that this position was achieved by moving the carriage 2i, i.e. the lower group 2 in the direction of arrow b, then, as Fig. 7 shows, the needle 4 becomes gray (A), the needle 5 blue (B) , needle 6 is either purple (C) or red (D), needle 7 is yellow (E) and needle 8 is green (F).

Is assumed according to Fig. 2 that this position by moving the carriage 2i, so the lower. Group 2 was achieved in the direction of arrow a, then needle 6 would be red (D), needle? yellow (E), needle 8 either green (F) or gray (A), needle 9 blue (B) and needle io purple (D).

In Fig. 9 it is shown how by further offsetting by more than two Needling or relocating any color change can be achieved so that z. B. on the three wales on which the pattern in the second ) Row begins, every six colors, of course in different rows, appear.

Claims (2)

PATENT CLAIMS: i. Thread turning device for flat edge knitting machines with two groups of folding sinkers mounted parallel to the chair needles, which are selected by a jacquard device, characterized in that both groups of folding sinkers are arranged so that they can be displaced relative to one another in the longitudinal direction of the machine. 2. thread turning device according to claim i, characterized in that that the folding plates of both groups in one each in the longitudinal direction of the machine displaceable carriage are mounted.
