    The mounting for the tension beam uses a connection means whereby the point of connection of the spring to the tension lever can be adjusted during operation. The connection means includes a toothed member in the form of a serration on the arm of the tension lever and a tooth element in the form of a rotatable pinion which is disposed at the end of a draw fork connected to the spring. A releaseable clamping means is also provided to prevent rotation of the pinion.

    Fig, I is a schematic representation of the gtrezlaglabemy usgroTsgvo; in fig. 2 hem rake with locking element; FIG. 3 - section A-A in FIG. 2
    A device for adjusting the basic threads on a weaver by the machine contains rigidly connected between the spurs levers 2 mounted on the frame 1 of the machine.
    On the shoulders 3 of the levers 2 set / Yun roller 4, in contact with the main yarns 5, and on the shoulder 6 of one of the levers there is a toothed rack 7. On the machine frame there is a fixed end of the spring 8, and a spring is connected with a fork 9, covering the lever 6 of the lever 2 with a lath rack 7. At the free end of the fork, a locking element is installed, made in the vice of the gear shaft 10 with a flat wrench II.
    On the gear shaft 10 between the pins 12 and 13 of the plug 9, the half-moon 14 is placed, one of the planes 15 of which is in contact with the plane 16 of the arm 6 of the lever 2. The slide 14 has fixing means made in the form of a groove 17 along the axis of the slide 14 and the screw 18 located perpendicular to the pa and tightening the cheeks 19 and 2O of the slide 14.
    In order to change the position of the End of the fork 9 on the shoulder 6 of the pin 2, loosen the screw 18 nevertically. At the same time, the popun 14 with a smaller effort engages the gear shaft Yu, then the key, the contact shaft with the coats 11 shaft gear Yu, turns at a suitable angle, the gear shaft shaft Y. As a result, the shaft of the gear shaft 10 is moved a certain distance along the spongy

    7, while the slide slides along the surface of the shoulder 6 of the lever 2. After the movement, it is necessary to tighten the screw 18 and
    . most fix the set position of the plug. Such a design of the device allows the tension of the main threads of the weaving machine to be controlled smoothly and easily.

    Claims (2)
    [1]
    Invention Formula
    1, A device for adjusting the tension of the main threads on a loom, containing a roller for contacting the threads, mounted on the machine frame by means of double-arm levers rigidly connected, a rack mounted on the free arm of one of the levers, and a retaining element in contact with it pivotally mounted
    in a fork fixed by means of a spring on the frame of the machine, characterized in that, in order to expand technological capabilities, the locking element in contact with the toothed rack is made in the form of a gear.
    [2]
    2. The device according to claim 1, characterized in that the fork has a half located between its cheeks and a covered locking element, and the lever arm carrying the rack has a guide for the slider, while the latter has a means of fixing the locking element.
