Description

The invention relates to a knit machine industry and concerns flat inlay machines with four needle beds.

A known flat machine has four cross-arranged needle beds equipped with needles and needle drivers, movable carriages according to the number of needle beds with locks for moving the needle drivers, and a web retracting mechanism located under one of the boxes of the needles 1.

In this mask, needles are used, one head of each of which has only a hook, and the other a hook with a tongue, and there are no platinum in the machine for transferring the loops. This reduces the technological capabilities of the machine: since it can only include a two-faced canvas, but not a purl.

The purpose of the invention is to expand the technological capabilities of the machine.

This is achieved by using two-headed tongue-like needles as needles, at the same time at least one pair of needle cases facing the web pull mechanism is equipped with platinum plates for

transfer loops, and the corresponding movable carriages have locks to move the said platinum.

FIG. 1 schematically shows four needles of flat machines, cross-section; in fig. 2-5 - needle cases in different phases in the yarn dvuh.hlitsevogo tubular knitwear, cross section; in fig. 6 and 7 is schematically depicted.

the process of knitting, respectively, of double-faced tubular knitwear and two-threaded tubular knitwear; in fig. 8 - needle cases and the carriage of a flat dome machine, cross section; in fig. 9 - needle bed and carriage in section, side view.

Plosk zalna machine with doubled

the number of horizontal needles has (see Fig. 1) four needle cases 1.-4, while the needles 1 and 2 are located in one plane, and the needles 3 and 4 -

in another, intersecting with the first plane. The needles 1 and 2, as well as the needles 3 and 4, together form a pair of needles of flat or P. reusable machine, and the needles 1 and 3 together form a pair of IGOLNITS of a flat needled machine with a V-shaped arrangement of needles. Needle needles 1,2c with double-head needles 5 and needle cases 3, 4 with double-headed needles 6 are the main part. The lower needles 1, 3 also have needle plates 7, 8, and needle plates 9, 10 and additional portable plates 11, 12 are provided in the upper needles x 2, 4. According to the invention, the flat batcher can be represented as a combination of two flat cage machines, with the help of which it is possible to know a two-faced tubular weave on horizontal needle beds. The process in a two-faced knitted knit yarn is shown in FIG. 1-6. In the manufacture of knitwear of this type, the parts 13 and 14 are put on the needles 5 and 6 of the needles 1 and 3 (see Fig. 1 and 6a). Each of the twin-head needles 5 and 6 has one loop. The carriage is, for example, on the right. The needle 4 at the right turn of the carriage (see Fig. 1-5) is retracted in advance. The carriage moves only from right to left. In this case, the first, third, fifth, etc., two-headed needles 5 are moved in advance by means of locks (not shown in the drawings) from the needle bed 1 to the needle bed 2. The position of the two-needle needle 5 after moving is shown in FIG. 2. At the same time, the second, fourth, pole .... two-headed needles 5 in the needle bed 1 reach the height of the confinement, and then are retracted back to the needle bed 1. During these needle movements, the thread is laid in a certain place in the two-headed needle that loops 1 and 2 form loops 15 and 16 (cf. Fig. 66). FIG. 2 shows looping in the needle bar 2, and FIG. 3 - looping in the needle bed I, with a double-head needle 5, needle platinum 7, 9 and portable platinum 11 (cf. Fig. 3) are respectively in the left or right adjacent channels of the double-head needle 5 (see Fig. 1.2 4 n 5). During the carriage stroke to the left, the double-head needles 5 from the needle bed 2 fall again. At the needle bed 1, the portable platinum 11 picks up the loop 15 dropped from their needles (see Fig. 4). After this, the loop 15 is immediately transferred from the portable platinum 11 to the needle, the phase of which is shown in FIG. 5. Before the carriage moves away from the needles, they are unclaimed vehicle. Locks on the level of the ridge. All the needles with their netles are now in the needle bed 1. On every first, third, p of that .... two-head needle, 5 hangs back loops, on every second, fourth, sixth ... two-head endpoint 5 hangs loop (see. Fig. 6d). The carriage is on the left. The needle bed 2 moves back, and the needle bed 4 is moved to the main position. The carriage is moving to the left of the nairavo. In this case, two-head needle 6, needle platinum 8 and 10, and portable platinum 12 needle cases 3 and 4 work the same as needle cases 1 and 2. In FIG. 6 g, d, shown needles and loopers for the twin-head needle 6 needles 3 and-4. FIG. Be shown is the movement of the thread of the needles 1 and 3, where it is possible to determine the double-faced tubular knitwear after the completed revolution or after the complete carriage stroke. FIG. Figure 7 shows the process in a two-thread knit jersey. On the double-head needles 5 and 6 of the needles 1 and 3 (see Figs. 1 and 7a), finished products 13 and 14 are removed. The needle room 4 is retracted. Each of the needles 5 and 6 has one loop each. The carriage is, for example, on the right. The carriage moves only to the left. At the same time, all the twin-head needles 5 are transferred in advance from the needle bed 1 to the needle cases 2. During the movement of the needle displacement, the thread is laid in front of the needle 5 in the appropriate place, and at the same time, the looped row is located at the needle bed 2 (see Fig. 2 and 76) . During the passage of the carriage, all the two-headed needles 5 are moved from the needle bed 2 to the needle bed 1, while at the second laying of the thread into the second looped row, but this time in the needle bed 1 (cf. Fig. 7c). The needle bed 4 is then moved to the main position, and the needle bed 2 is retracted, after which the carriage moves from left to right. In this case, all the two-headed needles 6 are transferred in advance from the needle bed 3 to the needle bed 4. During the transport of the needle, the thread is laid in the appropriate place in front of the two-headed needle 6, thus forming a looped row at the needle bed 4 (cf. (JJHI. 7). During the same carriage return, all the twin-head needles 6 CHOisa are fed back to the needle bed 3 to create it, while the second looping of the yarn leads to the second looped row (see Fig. 7e). Pas). / e shows a knitted non-interlocking re at the end of the first turn in the yarn, from which outside it can be sewn side loops. FIG. Figure 7G shows a knit weave after the end of the second turn in the yarn, in which the front loops can be seen along the entire length along the entire length. Permanent change of purl loops and facial loops gives the opportunity to get knit-free and .in smooth two-faced jersey.

Mechanical, electromechanical or electronic needle selection devices are used for the unlimited production of patterned knitwear.

FIG. 8, except for needle cases 1-4, the carriage 17 is schematically depicted.

FIG. 9 shows a needle bar and a carriage in the section, forks on the side, and on the carriage 17 one can see a double (two-system) lock. The cioyno lock allows an increase in the productivity of a flat plate machine with certain interlacings, for example, in the manufacture of a two-barred knit fabric. By a double lock (see Fig. 66), the double-head needle 5 is transferred ahead of the needle bed 1 to the needle bed 2, simultaneously in the same way and with the same stroke of the carriage in the second time. Then (see Fig. 6c), the two-needle needles 5 are again assembled in the needle bed 1. After the carriage has been completed, instead of one, two carts are turned in two ends (see Fig. 6).

When tubular knitwear is introduced with the proposed flat-panel mattress, the diameter of the tubular article is infused by changing the working width by choosing needles or salted platinum.
