    (5) METHOD OF MANUFACTURING PNEUMATIC TIRES PACKAGES
    The invention relates to the tire industry, and in particular to a method for producing tires for pneumatic tires from elastoplastics, in particular from polyurethane.
    The closest to the proposed technical essence and the achieved result is a method of manufacturing tires pneumatic tires, which form a carcass using the laying of a cord in the meridional direction from one side core to another, wrapping them and applying layers of breaker IS pa and tread tl .
    The disadvantage of this method is the uneven tension of the carcass, which, when perceived by the carcass 20 deforming forces under working loads, leads to deformation of the tire, as well as loose board, which, if the internal pressure drops, leads to tire damage.
    The aim of the invention is to ensure uniform tensioning of the carcass and elimination of the friability of the bead.
    The goal is achieved in that according to the method of manufacturing tires pneumatic tires, which form a carcass using laying cord thread in the meridional direction from one side core to another with their entwining and applying layers of breaker and tread, when the carcass is formed, the inner casing is first made made of elastomeric material, onboard cores are mounted on it with a gap from its outer surface, and then on the outer surface of the inner casing of tires placed at a constant tension of the cords, securing them to the bead cores by means of at least one of full WRAPPING of the bead cores and the bead core is pressed to the inner casing of the tire.
    A full winding of the side cores with a cord is carried out by twisting a cord of one of the side cores to form a loop, and after laying the cord on the outer surface of the inner casing of the tire, wrap a cord around the other side core to form a new loop, lay the cord thread on the outer surface of the inner core Corps pokrtsuki parallel to the previously laid cord yarn and pass the latter through the previously formed loop on the first side core
    The length of the cord between the preset side cords is equal to the length of the cord between the side cores in the assembled tire.
    The winding of the side cores with a cord is carried out by winding one of the side cores, pulling the cord to form a loop to the other side core, circling it around the latter and passing the free end of the cord into a loop to form a knot.
    The inner casing of the tire is manufactured with scars located on its periphery.
    FIG. 1 shows a tire made by the proposed method, a cross section; FIG. 2 shows a schematic arrangement of the cord between the bead cores; in FIG. 3 and t is a core for making the body, cuts; in Fig. 5, a tire without a core, section $ in Fig. 6 is a strut, 5 to Fig. 7, extension of the bead cores 5 in Fig. 8, wrapping the bead cores with a cord with a knot; Fig, 9 is the same, side view.
    The method is carried out as follows.
    They form a skeleton of a cord or cable, for which a wire of artificial fiber or steel can be applied using laying the cord in the meridional direction from one side core to another with twisting them. When the carcass is formed, the inner case 1 of the tire is first made (figure 5), which can be molded from polyurethane, using the core 2 (figure 13 and C).
    The latter has scars 3 on its periphery (FIG. 3). After the inner case 1 is made, the rolls on the core 2 form the scars C on the first one to evenly lay the cord 5. After this, the side cords 6 are mounted on the inner case 1 of the tire with a gap 0 from its outer surface. This gap can be obtained by installing spacers 7 in the locations of the bead; x cores 6 on the housing 1. Then on the outer surface
    the inner casing 1 tires are laid with a constant tension cord threads 5. At the same time, the latter are wound up from a reel 8 having a brake, pass over the tension rollers 9,
    The compensation roller 10 is fastened on the side cores 6 by at least completely wrapping one of the side cores (Fig. 2). Limit switches 11 and 12 serve to apply a brake on the brake and adjust the tension of the cord 5.
    After twisting the side cores 6 and the cord 5, they are pressed against the inner body 1 of the tire, and the struts 7 are removed (fig.b).
    The whole winding of the side cores 6 with cord 5 is carried out by winding 5 cord of one of the side cores with the formation of loop 13, and after laying the cord thread on the outer surface of the inner casing of the tire, wind the cord 5 around the other side core 6 (.2) the formation of the new flew 1, stack cord mend 5 on the outer surface of the inner casing 1 of the tire parallel to the previously laid cord yarn and pass the latter through
    previously formed loop on the first side core.
    The length of 1 cord 5 between the preset side cords 6 is equal to the length of the cord
    strands 5 between the bead cores in the assembled tire (Fig. 7). The bead cores 6 are kept in their position, i.e. adjacent to the inner casing 1 using

    fasteners 15, which, when fabricating the inner case 1, fit into the material of the inner case 1. The winding of the side cores 6 with the cord 5 can be done as follows: wind one of the side cores around (Fig. 8 pull the cord 5 to form a loop 16) the other side board card, bypassing it around the latter and passing the free end 1 of the cord 5 through the loop 16 to form knot 18. With this obvivNII cord cord is fixed to one of the side cores 6 by the double knot 19, A long free end of the 17-Loop 16 is passed under a different side core, and a passage along the periphery of the inner housing 1 is led to the first side core and circled around it from the inside until the loop 16 is at the height of the double node 19. In this case, the top 20 of the loop 19 with the free end 17 of the cord yarn 5 is secured by means of the knot 18 to the side core 6. The next 1; loop 1b extending from one side core to the other alternately from the inside and outside is circled around the side heart Nick 6 (Fig. 8). Tension of the cord yarn is set by a stronger or weaker tension of the free end 17. Fig. 9 shows a variant of the crepe Leni of the cord 5 "in which the loops 16 are not laid with the knotted yoke, By simply threading the free end 17 through the loop 16. After laying the cord 5 and fastening it to the side cores 6, the sides 21 (FIG. 5) and the running part 22 are installed, which can be molded simultaneously with the outer casing of the tire. Then the cycle repeats. Claim 1.
