    FIELD OF THE INVENTION The invention relates to a text industry and concerns a rotational helix carriage for a loom. The known rotary helix carriage for a weaving machine, comprising a drive shaft with two radial grooves, mounted for intermittent rotation from a drive, an eccentric, hingedly mounted on the drive shaft and connected by means of an earring and lever system with a helix of a machine, a spring-loaded latch, a mount, mounted on an earring and a lever system with a helix of a machine, a spring-loaded latch, a mount, mounted on an earring and a lever system with a helix of a machine, a spring-loaded latch, a mount. to an eccentric with the possibility of periodically entering into the grooves of the drive shaft, and a control lever mounted with the ability to interact with the dog, which is spring-loaded to the fixed end Y and mounted pivotally from the drive of the creep knife. A disadvantage of the known device: is the low reliability of operation due to the fact that in the carriage the control levers are driven to the working position in which the pawl is driven by the driving lever from the drive of the cushioning knife. can be disengaged. If the control rod is retracted to an inoperative position under the action of a spring, by means of which the control levers are pressed against the stop, the spring has a minimum off nenie and hence minimal tension. Therefore, the corresponding control lever, when running into a support, tends to cope with it, which requires additional time to stop. The aim of the invention is to increase the reliability of operation. The goal is achieved by the fact that in a rotational helix Carriage for a weaving machine containing a drive shaft with two radial grooves, installed with the possibility of intermittent rotation from the drive, an eccentric pivotally mounted on the drive shaft and connected through a link and lever system with a shaft of the machine, a podpruinny latch mounted on an eccentric with the possibility of periodically entering into the grooves of the drive shaft, and a control lever mounted with the ability to interact with the pawl, sub Armed to a fixed stop and installed with the possibility of rotation from the drive of the hoop blade, the drive of the hoop knife includes a double-arm lever, on one shoulder of which the knife is placed, and the other one is fitted with a groove and has a spring-loaded roller freely placed in this groove, which is installed with the ability to interact with the control a lever when the latter is in contact with a fixed stop. Figure 1 shows the carriage cut; figure 2 - the same, with a different position of the interacting elements; on fig.Z - drive unit of the shaft blade. The drive shaft 1, which is rotated intermittently through 180 ° from the main shaft of the weaving machine, has two radial grooves 2, into which the protrusion 3 which can be rotated around the axis 4 and which is under the action of extension 5 of the connecting latch 6, can engage with engagement The latch is located on the eccentric 7, installed pivotally on the shaft 1 and enclosed in the link 8. The latter is pivotally attached to the lever gear 9, by means of which the resulting reciprocating rotational movement shown by the boom 10 th, earrings 8 is transmitted to the corresponding heald loom. On shaft 1, there are several, for example, six to twelve driven parts 7, 8 (FIG. 1), namely for each eccentric hem 7 and 8 eye. All parts 1, 7 and 8. form an eccentric mechanism for driving and controlling all hedges of weaving stash. The stitches in accordance with the interlacing program for the main yarns are brought to the upper and lower sheds. To activate the latch 6 during operation, two fixed on the supporting pins 1-1, 12, turning control levers 13,14 or 15,16, which have hooks 17 on the free ends, which can rotate in the direction of the latch 6 Both control levers are connected to the shoulders 14 by means of a hinge 18. On the shoulder 14, platinum 20 is installed with the possibility of rotation around the hinge 19, which can be connected to the heddle blade 22 by the reciprocating 21 arrows. 22 is secured on a double-arm actuating lever 24, 25 revolving around the axis 23. The shoulder 25 has a slot 26 in which the roller 27 is mounted with the possibility of displacement, which is under the action of the extension 28 and extends along the entire length of the water shaft 1 and thereby covering all control levers 1 16 mounted side by side in each other. Spring 28 at the other end in POSITION 29 is fixed to shoulder 25. Control arms 15, 16 are installed with the possibility of interaction with the pawl 30 and the fixed stop 31 and are spring-loaded Lever 16 (f Fig. 3) is installed with the possibility of interaction with the rod 33, moving the reciprocating and connected with the plate 34 by means of the spring 35. The principle of operation of the device is as follows. In the position of the connection of the latch 6 (), the rotational movement of the shaft is transmitted along arrow A through the latch 6 to the eccentric 7, so that the link 8 and the lever gear 9 can perform a reciprocating rotational movement along the arrow 10, and the corresponding hem can alternately move from the upper position pharynx to the lower pharynx and back. The platinum 20 is thus engaged in engagement with the hedge knife 22, by means of which, respectively, when the lifting knife (Fig. 1) moves to the right against the action of the spring 32, it also moves to the right. Due to this, both control levers fall into (Fig. 1) a non-working position in which the dog 30 can run under both control hooks 17 without being connected to them. When the lifting knife 22 (Fig. 1) moves to the left, platinum 20, shoulders 14 and 16 of the control levers follow to the left under the action of spring 32, so that the control levers simultaneously fall into the working position. The pawl 30 is at this point in time not in the zone of action of one of the hooks 17. During the subsequent movement to the right of the heddle blade 22, the parts are again moved to the position in FIG. The roller 27, however, with all these movements remains in the cavity of slot 26. In order to stop the heddle in the upper or lower position, the platinum 20 from the unexposed software control device at the end of the left stroke of the helix knife 22 rises from the joint position indicated in Fig. 1, to the non-working upper position 20 "(Fig. 2), in which it is out of engagement with the helix knife 22. Before arm 16 is placed on the support 31, roller 27 lies on shoulder 15. With further movement of the lever 24 and 25, turns also arms 25 in the counter-clockwise direction further, so that the roller 27 comes out of the trough 26 under the influence of simultaneous additional tension springs 28 stretch (Figure 2). Thus, during the incursion of the arm 16 against the anvil 31, the spring 32 senses a slight tension, and the tension increases when the spring 28 is stretched, so that the control lever 15, 16 still encounters a stop under the action of sufficient tension, and oscillations on the stop or reported by the machine during subsequent work become completely harmless. The shoulder 16 is sufficiently firmly held on the jmope 31 by the tension of the spring 32 and especially 28. The roller 26 thus has a damping effect with respect to shocks or to machine vibrations. The doggie 30 (Fig. 2) runs onto one of the hooks 17 of the control levers, so that the release position of the pin 6 occurs, followed by the eccentric 7, stud 8, linkage mechanism 9, and the corresponding hemlock fall into the rest position. Before running up the shoulder 16 at the pore 31 returnable

    the rod 33 in FIG. 3 moves to the left. Due to this, an additional spring 35 with a washer 34 is mounted on the left end of the rod 33 towards the shoulder 16. The left movement of the parts 33, 35 and 34 occurs with a slightly increased storosti compared with the movement of the shoulder 16. After the shoulder 16 is in contact with the stop 31 of the rod 33, for some more short time, moves to the left, so that the spring 35 is compressed more strongly by the action of the contact stroke 34.

    Due to this, an additional pressing force on the shoulder 16 occurs. With the subsequent movement of the shoulder 16 to the right, the parts 33, 35 and 34 5 move to the right in FIG. 3 with an increased speed compared to the speed that the shoulder 16 has when it moves to the left. Due to this, the additional spring 35 10 is immediately unclenched and the washer 34 is lifted from the shoulder 16, with the distance between the parts 34, 13. ualichivaet with.
