    Apparatus for transversely stretching a travelling web of flexible material particularly of extruded plastics netting comprising a pair of travelling conveyor means for restraining the longitudinal web margins from moving laterally inwardly and opposed banks of staggered wheels or endless belts between which the web passes while in the grip of the conveyor means and which press on opposite surfaces of the web at alternate spaced locations across its width to transversely stretch the web.

    one
    This invention relates to the textile industry, namely, devices for spreading a moving web of elastic material.
    A device for spreading a moving web of elastic material is known, comprising a pair of spreading rollers installed one below the other with annular projections, the annular projections of one of which are located in the annular grooves of the other and the means for. adjusting the gap between the spreading rollers.
    A disadvantage of the known device is that different equipment was required for the longitudinal and transverse stretching of the plastic film or mesh.
    The purpose of the invention is the efficiency of transverse stretching of a plastic film or mesh.
    The goal is achieved by the fact that the device has a means for fixing the edges of the web, installed along the path of movement of the web and located in front of the spreading rollers, a heater, each ring
    the protrusion has, at least at its periphery, an anti-friction coating, and the annular protrusions of one of the spreading rollers enter into the annular grooves of the other to a depth that provides pleating of the web in the transverse direction.
    The means for fixing the edges of the web consists of two endless chains carrying clips for the edges of the web.
    The means for adjusting the gap between the spreading fibers consists of screws connected to the pins of the spreading rollers.
    Figure 1 shows the proposed device, side view; in fig. the same, end view} in FIG. 3 - the same plan view.
    The device for spreading the moving web comprises coils 1 and 2 fixed on pins at opposite ends of rash 3. Cloth 4 is unwound from coil i, wound on coil 2 and passed through a guide roller 5, gets onto the means for fixing the edges of the web consisting of two endless chains
    b and 7, driven by a drive with the same linear velocity with which the web moves. Chains 6 and 7 carry clips for the edges of the web 8 and 9. Clips 8 and 9 are located in the plane of the web and have a gap along the entire length of the chains equal to the original width of the web 4, so the clips 8 and 9 prevent lateral displacement of the longitudinal edges of the web in the direction of each other. to a friend.
    The web 4, gripped by clips 8 and 9, passes through the heater 10 to heat the web to. Then the canvas 4 passes through the rollers 11 and 12, fixed 13 and 14 with the help of dowels. Rollers 11 and 12 are installed one above the other and have annular protrusions, while the protrusions of one roller are located in the annular grooves of the other to a depth providing pleating of the web in the transverse direction. Each annular protrusion has a corrosion-resistant coating on the periphery.
    The device has means for adjusting the gap between the spreading rollers, which consists of screws 15 and 16 mounted on the shaft 14.
    The shafts 13 and 14 rotate in the opposite direction using a belt drive 19 at a speed at which the peripheral speed of the rollers is not linear to the speed of movement of the blade 4. The crimped blade 4, after being released from the clamps B and 9, passes through the guide roller 20 before winding it in a corrugated form on the coil 2.
