BACKGROUND OF THE INVENTION The invention relates to knitwear and knitwear machinery.

The purpose of the invention is to improve the reliability and improvement of service conditions.

Figure 1 presents the scheme of the locking system; Fig. 2 illustrates the interaction of the programmer-carrier with pushers; FIGS. 3-6 are a diagram of the interaction of | pushers with needles and lifting wedges; Fig. 7 is a diagram of the interaction of the pushers and the embedment wedge.

The locking system of the flat-fang knitting machine includes needle locks and pusher locks (Fig. 1). The needle locks contain wedges 1 and a double-sided wedge 2. Locks, pushers contain lifting wedges 3 and double-sided wedge 4. The locking system moves relative to needles 5 and pushers 6 as it moves to the left by 25 and 6

The program carrier 15 rotates, and the pegs 16 interact with the pushers. At the same time, the section 9 of the shank 10 of the pusher is sunk in an inclined hole in the bottom of the groove of the needle bed 11. As a result, the section 7 of the shank 8 of the pusher leaves the slot of the needle bed. In the end, the pusher (section 7) falls on the lifting wedge 3 (figure 4). Under the action of the lifting wedge 3, the pusher 6 begins to move into the slot of the needle plate t1, while the shank 10 slides along the wall 12

an inclined hole in the bottom of the groove of the needle plate, keeping the pusher from tilting. The pusher 6 in the process of movement acts on the shank of the needle 5 and sets it in motion (figure 5).

As a result, the needle 17 of the needle 5 is brought into the zone of action of the enclosing wedge 1. Further, this needle is involved in the loop formation process. Then under the action of the kulir wedge 2 needle 5

(Fig.6). After that, the shank 8 of the pusher 6 is affected by a sunken wedge 4 (Fig. 7), which removes it from the action area of the locks. The pusher 6 returns to its original position.

right and right to left, i.e. is bilateral.

The pusher 6 (FIG. 2) has the shape of a V-shaped plate, with section 7 of its shank 8 serving as a barrel apex, and section 9 of the shank of a sampling shank 10. In the initial position, the pusher 6 is located in the groove of the needle bar 11 below the needle 5. Section 9 of the shank 10 of the pusher corresponding to the extraction cable protrudes from the inclined hole in the bottom of the groove of the needle bed 11, not touching the wall 12 of the hole. recessed into the slot of the needle bar. The needle 5 is located in the lowest position. The old loops 13 are held by hooks 14 of needles 5. The program carrier in the form of a cylinder 15c with pegs 16 is located under the needle bar 11 opposite the pushers. The collet is of a V-shape with two tails 16 located on programmers, one of which is located in the body according to the required needle collection. the longitudinal groove, and the other - in the through-device works as follows, nominal, with the locking system containing the. pushes.

Claims (1)

Invention Formula A device for picking needles of a flat-fang machine, containing a needle bed with longitudinal grooves for needles and pushers and through grooves under the pushers, a program carrier disposed against the through grooves of the needle bed, and a locking system including lifting wedges of pushers, characterized in that, in order to increase reliability and improvement of service conditions, pushers (6). After that, the shank 8 of the pusher 6 is affected by a sunken wedge 4 (Fig. 7), which removes it from the action area of the locks. The pusher 6 returns to its original position. V-shaped with two tailings, one of which is located in the longitudinal groove, and the other in through are V-shaped with two tails, one of which is located in the longitudinal groove, and the other in the formula of the invention A device for picking needles of a flat-fang machine, containing a needle bed with longitudinal grooves for needles and pushers and through grooves under the pushers, a program carrier disposed against the through grooves of the needle bed, and a locking system including lifting wedges of pushers, characterized in that, in order to increase reliability and improving service conditions, pushers vypol II, II TG I 2i: A V 9u.2. f 7 8 iO 6 VAVA ii . 2 3 5 / j Fi.e .
