    The invention relates to textile machinery and relates to a clamping hook brake for a loom with a movable and fixed brake pads and with a servomotor for controlling the braking action of the mounting spindle driven by a servomotor.
    The purpose of the invention is to simplify the design and increase the service life.
    The drawing shows the proposed brake clamping hook, front view. ·
    The brake 1 of the clamping hook has an upper movable, 2 and lower fixed pads, equipped with brake linings 4 and 5, respectively. The upper brake shoe 2 can move up and down in the guide 6 and through the lever system 7 is connected to the slider 8, which can move up and down in the guide 9. The slider 8 oblique end surface 10 under spring pressure (not shown) is guided by the corresponding wedge end side 111 of the executive link in the form of an installation wedge 11. The opposite side 1 I 1 'of the installation wedge 11 is sent to the skeleton 12 of the weaving machine. A threaded hole 13 is made in the installation wedge 11, into which the threaded spindle 14 of the servomotor 15 is screwed. The lever system 7 consists of levers 16 and 17, which are connected to each other and to the brake lever 19 to close and open the brake 1 of the clamping hook.
    I
    The magnitude of the braking action of the brake 1 of the shuttle is recorded by means of two sensors 20 and 21 and the control device 22. The sensors 20 and 21 are applied along the braking distance of the shuttle 23 and are connected via the lines 24 and 25 to the control device 22 ν the output of which is connected to the servomotor 15 via electrical connections 26 and 27. Depending on the inhibitory effect, i.e. in dependent-. From the penetration depth of the shuttle 23 between the brake pads 2 and 3, the control device 22 generates a corresponding setting 5 signal for the servomotor 15 to move the setting wedge 11. If the shuttle does not penetrate the brake deep enough, i.e. if the braking effect is too strong, 0 is strong, then the setting wedge 11 is pressed to the left with the help of a servomotor 15, so that the upper brake pad 2 is easily lifted under spring pressure, which is equivalent to a 15 less strong braking effect when the brake is closed by the brake lever 23. If the shuttle 23 penetrates the brake too deeply, i.e., the braking effect is insufficient, then the servomotor 15 pulls the installation wedge 11 to the right, moving the brake pad 2 slightly down, which has the effect of more forces Noah braking dey25 Corollary. With the correct braking action, the control device does not generate any setting signal for the servomotor.
