    The weft feeder comprises a plurality of thread guide levers (1) oscillating between a withdrawn selection position and a projecting position for the feed or presentation of the weft. Both the movement from the selection position to the presentation position and the return movement of the thread guide levers (1) are controlled in a positive way by mechanical bar members (12, 13) made to oscillate by cam means (16, 17, 18) to engage, in different directions alternately, with members (7) operating the individual thread guide levers (1). <IMAGE>

    3.97 magnets according to the number of hooks, the means for selectively rotating the pins additionally lays down the bottom for the reverse pivoting of the support arms on which it is mounted, and the cam connected to the supports, while the hooks have sockets for this knife. The knives are parallel to each other, and their supports are coaxial. The knife supports are mounted telescopically, the axis of the levers is set at an angle to the axis of the knife supports. FIG. 1 shows the device, a general view; in fig. 2 - the same in terms of; in fig. 3-7 - stages of the lever movement. The device contains a plurality of arcs 1, each of which has an i 2 arm and is mounted for pivoting movement on axis 3. The rods 4 are mounted at the end of each captivity 2, with 1 each pin 4 terminated in glaze b for guiding the yarn. The levers 1 are positioned parallel to each other and are located around the rim. Axis 3 is located at an angle to the axis of the y-device and to the direction of movement of the jaws of the shuttleless loom on which the weft insertion device is to be mounted. The hooks 7 are rotationally connected to the central part of the shoulders 2. The hook 7 has a nest 8 and is terminated by a tapering end 9, which is removed by the connecting points of the hook 7 and the shoulder 2. The ends 9 of the hook 7 are located above the corresponding electromagnets 1O. Electromagnets are controlled by weft selectors. When a magnet is driven by an appropriate selector, its core 11, located inside the electromagnet 10, is displaced upward and slightly lifts the end 9 of the corresponding hook 7. When the electromagnet does not work, the core 1 remains inside the electromagnet 10 and therefore the corresponding hook 7 is not g. The device also holds the means, dp of the front panel with outward movement and the BUT of each lever 1. It has a pair of parallel knives 12 and 13, installed on the housings 14 and 15, which swing around the axis A. The supports 14 and 15 are coaxial and the telescopes are installed. The swing of the supports 14 and 15 is controlled by two cams 16-17 which are placed 74 on two opposite sides of the rotating disk 18. The cams 16 and 17 engage with the corresponding cam rollers 19 and 20, which are respectively mounted on the supports 14 and 15. The disk 18 rotates around its axis under the action of the drive weaving. The cams 16 and 17 have a different profile, therefore the supports 14 and 15 make independent swinging movements. The first knife 12 is adapted to engage a jack 21 (FIG. 3) formed outside the jack 8 of each hook 7 when the hook end 9 is lifted under the action of the core 11 of the electromagnet 10. The first XU 12 cannot snap the jack 21 when the hook 7 is not lifted The second knife 13 on the other side is adapted to engage the valleys 22 formed inside the socket 8 in each hook 7 when it is in the position shown in FIG. 7. Describe above the parts of the device that are mounted and work so that the hooks. 7 completely out of engagement with the blades 12 and 13 during the sampling time, so that the hooks can be rotated by means of the cores 11 of the electromagnets 10. The knife 12 engages the socket 21 only when it moves to the levers 1. At this stage of operation, the knife 13 does not engage the socket 8. At the end of this movement is forward movement. The knives 12 and 13 are replaced by an anti-drain, and the knife 13 then engages the nest 8, thus moving the hook 7 with the lever 1 in the opposite direction. At this stage of operation, the knife 12 does not engage the nest 21. If the hook 7 does not rise under the action of the electromagnet 1O, the knives 12 and 13 repeat their swinging movement, but since the knife 12 does not engage the nest 21, the hook 7 does not move, a. the knife 13 moves inside the socket 8 along its entire length. . The device also includes springs 23 coupled with levers 1, so as to keep the unselected levers 1 in a stable, retracted position, and the springs 24, which provide each connection with the cru (7, and the springs 24 are adapted to hold the hooks 7 in non-working As shown in Fig. 2, the axis of rotation 3 on which the levers 1 swing is not parallel to the axis of rotation of the supports 14 and 15, but is at an angle to this axis and at an angle to the direction of movement of the clamps on the loom. Therefore, the eyes 5 rods 4 pinch 1 pin lag with along a straight line, which essentially connects the place where the weft thread is fed, and the place where the fabric begins, and moreover, is likewise at an angle to the direction of movement of the clip carrying the weft thread. The device works as follows When the weaving machine is in operation at the moment when the device is in the middle of the selection of the weft yarn, and 1FLO 7 of the knives 1 are free of knives 12 and 13 (Fig. 3), the weft selector actuates from electromagnets 1O, which in turn act sa corresponding levers 1 by lifting the ends 9 of the respective control hooks 7 (Fig. 4 The disk 18 rotates and the rollers 19 and 2 of the cam followers of the supports 14 and 15 the knives 12 and 13 run along the cams 16 and 17 of the disk 18, rolling the knives 12 and 13 by the cams mentioned. Therefore, the knife 12 hooks the outer 21 and 7 of the hooks 7 of the levers 1 to push them, waving the oscillations of the levers 1 around the ocsi 3, to to feed the weft yarn to a clamp. During subsequent rotation of the suit 18, the direction of movement of the knives 12 and 13 is changed, and the knife 13 hooks the socket 8 of the hook 7. The knife 13 moves 7 B. opposite to the original direction. In the proposed device, the levers 1 are controlled in the forward both reverse and forward reenactments. Both stages of the work occur at strictly defined speeds, thereby minimizing the negative effects of inertia, idling, recoil, and other disturbances. Which are typical in known devices. The application of the invention will allow the swiveling speed of the weaving machine. Formula, and inventions 1. The device for feeding the weft yarn to the weaver plotter, containing levers mounted on a common axis, carrier rods with eyes for the weft yarns, hooks, one end of each of which is pivotally mounted on the corresponding. a lever, and the other has a socket, a means of selectively turning the levers to the feed position of the weft thread to the plotter and reversing their rotation with a knife for interacting with hook sockets mounted on cam-supported supports, and electromagnets according to the number of hooks, characterized in that In order to increase speed capabilities, the Bbfracking lever rotation tool additionally has a knife for reversing the levers, supports on which it is installed and a cam connected to the supports, while the hooks have sockets for these Wow, a knife, 2.

    Claims (4)
    [1]
    The claims make it easier for clamps to hold and guarantee the transfer of weft threads to the spacer.
    The device operates as follows. fifteen
    When the loom is operating at the moment when the device is in the states preceding the selection of the weft thread, and the hooks 7 of the levers 1 are free. From the knives 12 and 13 (Fig. 3), the weft 20 selector drives one of the electromagnets 10, which turn, act on the corresponding levers 1 by raising the ends 9 of the corresponding control hooks 7 (Fig. 4) 15, the disk 18 is rotated, and the rollers 19 and 20 of the cam followers 14 and 15 of the knives 12 and 13 run along the cams 16 to 17 of the disk 18, causing swinging knives 12 and 13 with said cams. Therefore, the 30th knife 12 hooks the external socket 21 of the hook 7 of the levers 1 and pushes them, causing the levers 1 to swing around the axis 3, to the position for feeding the weft thread to the clamp. 35
    During the subsequent rotation of the disk 18, the direction of movement of the knives 12 and 13 changes, and the knife 13 engages the socket 8 of the hook 7. The knife 13 moves the HOOKS 7 in the opposite direction to the 4Q. The cams 16 and 17 are profiled with a stand for the levers 1 in order to ensure sufficient time for the selection of the corresponding levers 1.
