    The tensioning apparatus for adjusting the tension of a whip roll in a weaving machine employs an adjustable eccentric element which is connected to the tension spring. The eccentric element includes an eccentrically mounted pin which can be moved about an axis of the eccentric element in order to make an adjustment in the force supplied to the tensioning lever by the spring.

    The invention relates to textile machinery and can be used on I-looms.
    The aim of the invention is to improve the quality of the fabric by improving the accuracy of regulation of the main threads.
    In FIG. 1 shows the main controller in which the eccentric is mounted on an axis mounted on the machine bed; in FIG. 2 - the same, top view (partially in section); in FIG. 3 - the main controller, in which the cam is mounted on a cam lock; in FIG. 4 - the same, top view (partially in section).
    The main controller of the loom consists of a rock 1, mounted on one of the shoulders 2 of each of the two shoulders levers 3, the second shoulder 4 of each of which is equipped with a cam lock 5 with recesses 6 for connecting with the hook 7 of the left end of the tension spring 8, which serves as an energy accumulator (Fig. .1 and 2).
    The lever 3 is located with the possibility of rotation with the help of the bearing 9 on the axis 10, mounted in the frame 11 of the machine. The axis 12 of the rock 1 is installed in a self-aligning roller bearing 13.
    At the right end (FIGS. 1 and 2) of the tension spring 8 there is a leash 14, which is connected to the eccentric pin 15 of the eccentric 16. The concentric pin 17 of the eccentric 16 is mounted on the machine bed 11 and is equipped with an adjustment head 18 with recesses 19 and a scale 20, and .with thread 40 bout 21 for installation nut 22.
    According to the second embodiment, (Figs. 3 and 4), the tension spring 8 is fixed with its left end in a Z-shaped leash 23 on which an eccentric 16 is mounted, an eccentric pin 24 with a thickening 25 of which is engaged with the recesses 6 of the cam lock 5.
    The main regulator operates as follows.
    When the tension of the main threads 26 is changed, the tension of the spring 8 is adjusted, for which the adjusting nut 22 is loosened, and the adjusting head 18 is rotated to the desired position on the scale 20 using the tool inserted in the recess 19, after which the adjusting nut 5 22 is again tightened. In this case, the leash 14 moves along the axis of the tension spring 8, for example, by a distance X, as a result of which the spring tension increases and, consequently, the moment acting on the shoulder of the two shoulders lever 3 increases.
    In the second embodiment, the operation of the main controller is as follows.
    • 5 During operation, by turning the eccentric 16 accordingly, the eccentric pin 24 is set, for example, to the position shown, while the leash 23 moves along the shoulder 4 by a distance Y, as a result of which the moment acting on the shoulder 4 changes.

    The invention relates to textile machinery and can be used on weaving machines. The aim of the invention is to improve the quality of the fabric by increasing the accuracy of the regulation of the main threads. FIG. 1 shows the main regulator in which the eccentric is mounted on an axis mounted on the machine bed; in fig. 2 - the same, top view (partly in section); in fig. 3 - the main regulator, in which the eccentric is mounted on the cam lock; in fig. 4 - the same, top view (partly in section). The main regulator of a weaving machine consists of rock 1, mounted on one of the arms 2 of each of the double-arm levers 3, the second shoulder 4 of each of which is equipped with a cam latch 5 with recesses 6 for connecting via the hook 7 of the left end of the tension spring 8, which holds the accumulator The torus of energy (Figures 1 and 2) o The lever 3 is located rotatably with the help of the bearing 9 on the axis 10, fixed in the frame 11 of the machine. The axis 12 of the rock 1 is installed in a self-aligning roller bearing 13. At the right end (Figs. 1 and 2) of the tension spring 8 there is a leash 14, which is connected with the eccentric pin 15 of the eccentric 16. The concentric pin 17 of the eccentric 16 is mounted on the base 1 of the machine and Equipped with an adjusting head 18 with recesses I9 and a scale 20, as well as with a thread 21 for an adjusting nut 22. In the second embodiment, (FIGS. 3 and 4) the tension spring 8 has its left end fixed in a Z-shaped leash 23, on which the eccentric 16 is installed, eccentric pin 24 with a thickening of 25 which engages with recesses 6 ku of a latch retainer 5. The main regulator operates as follows. When changing the tension of the main threads 26, the spring 8 is adjusted for tension; d, the adjusting nut 22 is loosened, and the adjusting head 18 is turned to the desired position on the scale 20 using the tool inserted into the recess 19, after which the adjusting nut 22 is tightened again. In this case, the driver 14 moves along the axis of the tension spring 8, for example, by distance X, as a result of which the spring tension increases and, consequently, the moment acting on the shoulder 4 of the double-arm lever 3 increases. is as follows. During operation, by appropriate rotation of the eccentric 16, the eccentric journal 24 is set, for example, to the position shown, while the driver 23 moves along arm 4 to distance Y, to re-; As a result, the moment acting on the shoulder 4 is changed. 1. The main regulator of a weaving machine containing a rock mounted on one of the arms of each of the two shoulders, the second arm of each of which is provided with a cam lock with notches for connecting one of the ends of the spring, the second end mounted with a finger on the base of the machine , characterized in that, in order to improve the quality of the fabric being produced by increasing the accuracy of the regulation of the main threads, it has an eccentric connected to one of the ends of the spring to adjust the moment, vuyuschego from her double-arm lever.
    [2]
    2. The regulator according to claim 1, about tl and h ay i and so that the eccentric of the grass is laid on the finger, by means of which the spring is mounted on the frame of the machine.
    [3]
    3. The regulator according to claim 1, characterized in that the notches of the cam retainer are shaped according to the shape of the axle of the eccentric, the latter being installed in one of the notches of the cam retainer and connected by means of a driver to the end of the cam retainer
