The invention relates to knitwear production.

The purpose of the invention is to increase productivity and expand technological capabilities in hall machines,

Figs 1 and 2 show the trajectories of the movements of I1 when there are curly and double curly knit in two curved loops on two lines x, respectively; in FIG. 3, the trajectories of needle movements while in the curling knit are two successive cycles of looping on one line; Figures 4 through 6 show a method for knitting a knitted fabric with two offset loop loops of two strands on two looping lines; Fig. 7 shows a single crochet knit of two offset loop cycles of two strands on two looping lines; Fig. 8 is a graphic record of a single knit; Fig. 9 shows the double knit knitwear of two offset 1 loop loops of two strands on two looping lines; FIG. 10 shows a graphical record of double knitwear.

In Figures 4-6, needles 1-27 are indicated. The proposed method is feasible on flat, round, revolving kulirnye in hall machines, flat and

 Round basics hall maschineh. For this, the loop-forming mechanisms are structurally modified in such a way that the needles in the grooves of the needle beds form, for example, two lines of needles, which are affected by the means for moving them, arranged respectively by the needle lines and displaced relative to each other so that the trajectories K, 0 , P, T (Fig. O. needle movements, corresponding to the first loop of formation of the first line, are offset with respect to

To the paths C, 3, F, H of the second loop of formation of the second line. The intersection of the trajectories at the conditional point C (Fig. D). and at the conditional points C and C1 (fig, 2) correspond to the combination of operations of looping, where L is common

JO the length of two successive cycles of looping on one line of forming loops forms a completed loop of two threads. On flat bases of the casting machines 5, the loop-forming mechanism is structurally modified so that one needle bed contains several lines of spikes, which correspond to the eye combs with corresponding

The method in a knit (Fig. 4-6) with two shifted cycles of looping from two strands on two lines of looping is carried out in the following way.

The first loop of looping of the first line by the first operation. Conclusion is combined with the operation of Laying the second shifted loop of looping of the second line, taking into account the initial position of the loop-forming organs - the needles of two lines. Serial numbers of needles involved in looping are determined by the known

where i is the serial number of the nth needle; P - cycle number; E - the difference of progression.

The needles, defined by the formula I. 1 + 2 (n - 1), are involved in the looping of the first cycle of the first line.

The needles, defined by the formula AND 2 + 2 (n - 1), participate in the loop formation of the second cycle of the second looping line.

The process of yan is carried out with P 2; M 2, Knitwear (Fig, 7, P 2, M 2) contains loops A of yarn a, obtained by the first loop of looping, the length of loop-shifted loop of the first pattern; loops B from a thread to a second loop, looped by looping loop of the second

The trajectories K, 0, P, T of the movement of the needles of the line — one looped row and loop — the first background level and the trajectory K1.0, or B from thread b, obtained by the first P1f Tl of the second pattern — are shifted by looping the first loop to C, 3, F, H paths of the first pattern and with respect to the paths C1, 31, F1, H1 of the second pattern of the second loop of looping, where L is common
