    The fabric take-off device comprises a fabric take-off roller mounted to be movable transversely of its longitudinal axis and two associated rod-shaped fabric guide elements which are mounted on fixed axes for supplying the fabric to the take-off roller and for taking the fabric away from the roller. The fabric tension causes the take-off roller to be pressed against the two guide elements due to the movable mounting of the roller. This contact-pressure force increases automatically as the cloth tension increases. A very reliable fabric take-off is obtained without slipping of the fabric on the take-off roller. To avoid damage to the fabric, the take-off roller need not have a rough surface nor need any pins, but may have a relatively smooth surface made, for example, of plastics.

    The invention relates to textile machinery and relates to a mechanism for winding a fabric on a loom.
    A known mechanism for wounding a fabric on a loom, comprising a shaft connected to the machine drive, mounted to move in a direction perpendicular to its axis between the guide shafts mounted at a distance smaller than the diameter of the shaft.
    Closest to the present invention is a fabric winding mechanism comprising a roller mounted under the shaft to support it, while the distance between the support roller and the second guide shaft in the course of the movement of the fabric is less than the diameter of the shaft. Thus, the val val with a slight tension of the fabric rests on the support roller and on the guide shaft, and with an increase in the inaturation of the fabric the val is in contact with the guide shafts, the first of which is driven by actuator 1 during the movement of the fabric.
    The disadvantage of this mechanism is the slippage of the fabric when it is slightly tensioned, since the shaft is not pressed against its own weight. At the same time, with an increase in the fabric tension during operation, the impact of the shaft through the fabric with the drive guide shaft may occur. Periodically impacting the shaft with the drive guide shaft and the support roller leads to a decrease in the quality of the fabric produced on the machine and reduces reliability operation of the whole mechanism,
    The purpose of the invention is to increase the reliability of the mechanism.
    This goal is achieved by the fact that the mechanism is wound on

    weaving machine, which has a shaft, connected with the machine drive, mounted for movement in a Direction perpendicular to its axis, between guide shafts mounted at a distance less than the diameter of the shaft, has a means for pressing the shaft shafts, with the first guide shaft in the course of moving the fabric - installed with the possibility of free rotation.
    The means for pressing the shaft against the guide shafts is made in the form of a spring-loaded strip in contact with the cylindrical surface of the shaft.
    In this case, the axis is connected with the drive of the machine by means of the Hooke hinge,
    The Vsela guide is mounted on one bracket © mounted on the machine frame.
    Bracket Ig-Geet support grooved surface in contact with the cylindrical surface of each shaft.
    In addition, the mechanism is fixedly mounted in front of the guide shaft in the course of the movement of the tissue rod, on which screw grooves are made, the flow rate is from the middle of it.
    Fig. 1 shows a technical scheme of the weaving atank in Fig. 2 A. on fng.1g on fig-3, 3 - section B-B on .2. in fig. 4 and 5 are variants of disposing of the mechanism for winding the fabric, FIG. 5 is a variant of the upper arrangement of the shaft with respect to the guides.
    On the loom, the main threads 1, after naval 2, pass through the main observer and the shedding mechanism, after which the fabric, 3, passes through the winding mechanism 4, fabrics. Next, the wire 3 enters the product line 5, the winding mechanism of the fabric 6, mounted between the guide shafts 7 and 8, wherein the distance A between the shafts is less than the diameter D of the shaft by 6. The shafts 7 and 8 are located above the wall by 6, under which is placed the means for pressing the shaft to the guide shafts, the form of spring-loaded springs 9 strips 10, mouth copulating in the slot 11 of the bracket 12 fixed to the machine rame.13. The bracket 12 has grooved surfaces 14 and 15 for the shafts 7 and 8, respectively. The shafts 7 and 8 are freely installed in these grooves. Valnb is mounted for movement in a direction perpendicular to its axis and is connected by means of a Hook 16 hinge, gears 17-19 and pulley 20 to the main shaft of the machine. The surface of the 21 val 6 can be covered with plastic. The surface of the spring-loaded strap 1, in contact with the jack, is made along the radius of the shaft by 6. In front of the first guide shaft 7, in the course of moving the fabric, is installed to spread the fabric of the tanga 22, on which helical grooves are made, diverging from its middle. The shafts 7 and 8 of the fabric winding mechanism can be installed in a horizontal plane (FIGS. 1 and 4), and in an inclined plane (Figure 5), both in the immediate vicinity of the edge of the fabric (Figure 4) and in the distance from it (figure 5). If the mechanism is removed from the edge of the fabric, an additional guide roller 23 can be installed between the rod 22 and the guide shaft 7. Another rod 34 can be installed under the rod 22 on the other side of the fabric to spread the fabric (Fig. 5). As an embodiment, val 6 may be located on top of fixedly mounted free cylindrical elements 25 and 26 (fig. B). In this case, the contact of the shaft with the elements is made at the expense of the weight of the shaft. The bypass elements 25 and 26 are integral with the bracket 12. During operation of the machine, the fabric 3 contacts with the rods 22 and 24 - flattens, bends around the guide shaft 7, val 6 and the guide shaft 8, and then winds onto the product roller 5. In the winding mechanism, the fabric 3 is located between the guide shafts 7 and 8 and the shaft 6, as well as between the spring-loaded strip 10 and the shaft. Under the action of increasing or decreasing the tension of the val nave tissue, in a large or at least presses the fabric against the guide shafts 7 and 8 and the fabric without slipping is withdrawn from the formation zone. Reliable retraction is achieved due to the possibility of moving the drive shaft by 6 in the direction perpendicular to its Bei and not connected to the drive by the guide shafts 7 and 8 or bypass stationary elements 25 and 2b that are freely mounted in the grooves. /; S: 5% i 5 i; $ S.
