Fig. 1 The invention relates to a textile milling machine and relates to a device for forming a double carpet pile knot on a carpet weaving machine. A device for forming a carpet vapa on a carpet weaving machine is known, comprising a knot-free needle bed with needles, the webs of which are mounted to be in contact with the cam pusher, and a carriage mounted, movable, at the needle and carrying the knots, and knitted hooks and pulleys, and thread straps, and with knotting knots and carrier knots, zelgnye levers and pullers, and yarn stitches, and with knotting knots and carrier of knots, zalgnye levers and fleece straps, and yarn needles, and knotting and knotting and knotting tools, and yarn stitches, and yarn stitches, and with knotting arms and knotting knotters and pillow stitches. A disadvantage of the device is the presence of a second carriage with a drive in the form of a lead screw, K1 which is schematically connected: with the first carriage. The need to rotate the two spindles, which move the carriages in the start-stop mode, limits the speed limit of the device, which reduces its productivity. The purpose of the invention is the noBbiueirae of a device for forming a carpet knot on a carpet weaving machine. . The goal is achieved by the fact that a device for forming a carpet knot on a carpet weaving machine contains a fixed needle bed with needles, the webs of which are installed with the possibility of combining with the cam pusher and the carriage mounted along the needle bed and the fixed parts of the levers and pile thread guides, has a main thread guide, made in the form of Iggyrey, mounted between the needle bed and the carriage, while the cam is mounted on the carriage. Fig. 1 shows a device for forming a carpet knot on a KOBpOTKaiucoM machine, a kinematic scheme} in Fig. 2, a kinematic scheme for selecting pairs of warp threads. The device contains a carriage 1, (fig, 1) mounted on a carpet weaving machine and moving along guide 2 using a non-moving wheel 3 Screw 3. On the carriage 1, there are knots 4, 4 guides, 1 course thread, 5 scissors, a multi mechanism 7, the gearbox 8 and the electric motor 9, the device also contains a fixed needle bed 10 and a bar 11 with main thread guides made in the form of pins 12, 1 022 are fixed to the machine frame, in the slots of the needle bed 10 are installed needles 13 with Pts on the rod and elongated hookKatv ffl; A pusher 14 interacts with the needles 13, which can be rocked on an axis 15 and contact with a cam 16 mounted on a camshaft 17 of the device. To the cam 16, the pusher 14 is pressed against the spring 18 (FIG. 2-). On the carriage 1, there is a nut 19, mounted on a stationary driving screw 3 and executed at the same time with a gear wheel 20 meshed with a gear wheel 21 located on the output shaft of the Maltese mechanism 7 located on the camshaft 17 Sfig, 1), Thread 22 The bases in the 1 needle of the needles 13 are arranged in pairs, and the napbi, in turn, are separated by pins 12, the pitch of the pins and the pitch of the needles correspond to the pitch of the double pile knots in the transverse row of the frame (Fig. 1). The hooks of the needles 13 are elongated so that the threads 22 of the warp do not fall out of them when the pharynx is formed using a heald mechanism (not shown). The device works as follows. The electric motor 9 rotates the camshaft 17 through the gearbox 8, which, in turn, provides the nut 19. through the little 7 mechanism. On the lead screw 3 to the start jTonHOM mode, which moves the carriage to the OTs1 step after each cycle (Fig. 1). After stopping the carriage 1 in the next position, the pusher 14 under the action of the cam 16 on the distributor shaft 17, interacting with the needle needle 13 another, takes another pair of warp threads 22 of the base, lifts them, and the pin 12 between threads 22 separates the threads 22 are paired from each other, ensuring a reliable hit of the nodes of the lever arm 4 between the threads of 22 pairs. The positions and speeds of moving the pair of warp threads 22 are provided by the cam 16 profile, and the return of the needle 13 to its original position is due to the elastic forces of the warp threads 22 (Figs 1 and 2). The use of a device to form a carpet knot with a reliable selection mechanism steam base base i have
