    A device for presenting the weft in weaving looms comprising a plurality of oscillating presenting rods having their free end in the form of an eyelet for the weft thread, a corresponding plurality of control levers for the rods, magnet means for causing the oscillation of the control levers under the control of a weft selection device, and a transversal bar for operating the levers being adapted to engage an appropriate seat of those of the levers having been selected by the selection device through the magnet means - the transversal operating bar has a flattened section with mixed-line contour, adapted to freely insert itself into the seat of the control levers of the device, the seat having a corresponding mixed-line contour section, and to respectively cooperate with the seat (like a pin in a hole), depending on the reciprocal position between the transversal bar and the seats of the levers; and the bar is fixed to an end of at least one guide lever which controls the position thereof during its movements and which is pivoted, at its other end, to a connecting rod oscillating about a fixed point.

    The invention relates to the textile industry and can be used in shuttleless weaving in devices for forming a duck pattern.
    A device for forming patterns on shuttleless weaving machines is known, comprising spring-loaded yarn feeders mounted on a common axis, carrier rods with eyelets for weft threads, hooks, each end of which is hinged with a respective thread guide, and the other has a socket, an interaction knife with kpro4kov sockets, mounted on a cam drive pusher, and software node with electromagnets ij. .
    The disadvantages of the known device are low reliability in operation, as a result of insufficient accuracy of the movement of the hooks and weak engagement between the knife and the nests of the hooks, increased vibration and noise.
    The purpose of the invention is to increase reliability and reduce vibration.
    The goal is achieved by the fact that a device for forming a pattern on a weave to an shuttleless loom, containing spring-loaded yarn guide mounted on a common axis, carrying rods with eyes for weft yarns, hooks, one end of each of which is pivotally mounted on its respective yarn feeder and the other has a nest, a knife. for interacting with hooks, mounted on a cam drive pusher, and a software node with electromagnets according to the number of shouts, has at least one lever and a link with one end fixed rigidly on the knife and the other pivotally connected to the lever, while the working surfaces of the knife They are formed by two cylindrical surfaces of different radius, having a common axis of rotation, and the hook nests have COOT no stem, shaped in sections.
    Fig, 1 shows the device, a general view; in fig. 2 — linkage of a lever, an earring, and a knife with a hook; in fig. 3 - knife knot with knot hook. . .
    The device comprises a series of curved support rods 1 which are provided at their free end with eyelets 2 for a weft thread and are mounted so that the other end attaches to the end of the thread stitches 3 swinging around axis 4. The support rods 1 are usually held in the retracted position by springs 5, but each of them can be actuated or guided by a corresponding adjustable hook b, which rotates.
    intermediate point 7 of the yarn feeder The hooks 6 are held near their end opposite to that which is rotated on the yarn feeder 3, opposite the electromagnet cores 8 of 9 and pressed against the named cores by springs .10. Each hook 6 is provided with a socket 11 for engagement by means of a knife 12 located transversely to the hooks 6.
    The knife 12 is rotated idle at the ends of a pair of pushers 13 that swing around point 14 by means of a cam 15 and a roller 16 controlled by a machine drive.
    In the known devices, when the weaving loom weaving device starts working, one or more electromagnets 9 are excited and, accordingly, the cores 8 are pulled out. The corresponding hooks 6, which swing at point 7 of the yarn feeder, nod. 3. The hook nests 11 are hooked by means of the knife 12 so that when the latter is pushed to the rods 1 by means of movement driven by the cam 15 and the pusher 13, the yarn feeders 3 and the rods 1 are forced to swing from the designated position to the weft direction, which is guided through eyes 2 swinging rods.
    In the known devices, the engagement between the knife 12 and the sockets 11 of the hooks b always occurs with a certain weakening, therefore, the movement of the hooks could not be directed with the desired accuracy, vibrations and noise occurred, and it is likely that ; This thread was not always able to be in the clamp carrying the weft thread and so on.
    The invention provides a special engagement between the HOJKOM 12 and the respective sockets 11 of the hooks b, allowing, on the one hand, a lung; and the free hit of the knife in the named nests of willows of equal temperature to its easy and free exit from there, on the other hand - tight mutual engagement, practically without a donkey, between the same constituent elements when the knife moves to force the hooks b and consecutive 1 to make an oscillating working movement. - For this purpose, the knife 12 has a flat section with a heterogeneous contour line, which is defined by boundaries (Fig. 3.), by means of two arc segments 17 and 18 and straight segments 19 and 20, which connect the ends of do year Arc segments 17 and 18 have a common center 21 inside sections, but have different radii
