    This invention relates to the manufacture of pneumatic tires for vehicles.
    The purpose of the invention is to improve the quality of tires with multilayer braker.
    FIG. 1 shows the proposed device; in fig. 2 - drum for belt installation; on fr1g. 3 - ring shape with molded protector | in fig. 4 - the same, after connecting the tread with the first (1M belt layer; in Fig. 5 - the same, with a belt-projector bracelet and a layer of rubber sub-briqueria; in Fig. 6 - a connection between the molded frame and belt-protector 7 shows the imposition of parts of the toe of the base and heel of the bead; FIG. 8 - the assembled tire is ready for vulcanization.
    The device dp for the manufacture of pneumatic tires contains one dfl several ring forms 1 dp for the manufacture of the tread. Each form 1 is formed by forming sectors 2 installed in an annular steel body 3, side portions 4 and 5, and clamping rings 6 and 7 for fixing the beads of the tire. Sectors 2 completed
    one
    removable and secured in the case, 3
    with the help of protrusions 8. The inner surface of the sectors 2 is made with a profile that ensures the formation of a tread with a given pattern of the running part. The device has a support for the form 1, an actuator for its rotation (not shown), a drum 9 for installing the tread in the ring form 1 and means 0 dN for forming an annular groove on the inner surface of the tread dp centering breaker Drum 9 is made in the form of a steel ring I1 installed on a system of bearing arms 12, and an elastic, almost flat annular inflatable chamber 13 placed on ring 11. The outer diameter of the drum 9 is smaller than the internal diameter D of form 1, which ensures free entry into the form 1 of drum 9 with the workpiece protector.
    A tool 10 dp of forming an annular groove on the inner surface of the tread for centering the breaker is complete as a set of interconnected ends of rigid forming shoes 14 forming the annular stepped surface 15 and mounted on a non-attached frame 16,

    providing a change in the outer diameter of the tool 10 from the minimum in the folded state, allowing the introduction of the tool 10 b form 1, to the maximum corresponding to the diameter of the inner surface of the tread.
    The device also has a drum for installing a breaker, which is made in the form of segments 17 placed between the supporting cylindrical elements 18 and the envelope segment 17 and the elements 18 of the band 19 of reinforced rubber rigidly connected to the elements 18. The segments 17 are made with lateral the surface 20 having the same radius of curvature with the bandage 19 in its working position and is provided with studs 21 to hold the bandage 19. By means of the relative movement of the studs 21, the radial circumference bar is adjusted Abana. Each supporting element 18 is rotatably mounted on a cantilever shaft 22 mounted on an end frame (not shown), the possibility of radial movement of the support element 18 to the center of the drum (shown by arrows X in Fig. 2). The shafts 22 are driven E (not shown). The segments 17 are located on triangular bases 23 with the possibility of radial movement along the uprights 24. Springs 25 are designed to push the segments in the direction from the center of the drum. The bases 23 are mounted on a front frame with a possibility of sliding to ensure an initial fit during installation. By adjusting the position of the shafts 22 and the bases 23, it is possible to use the bandages I9 of different perimeters in accordance with the size of the belt.
    The device also has a means for pressing and shaping the inner surface of the belt and tread band according to the shape of the outer surface of the molded frame, which can be made similarly to the tool 10, the ring pads 26 and 27 to the ring form 1 to hold the bead rubber and cf (for the flat assembly of the frame and its molding into a toroidal shape and the connection of the frame with the belt and tread band by any known method.
    The proposed method is carried out as follows.
    On b Araban 9 stack billet of unvulcanized rubber, obtained by extrusion or winding. Then the drum 9 with the billet is introduced into the annular form 1 preheated to 80-100 0 and its inflatable chamber 13 is filled with compressed air. At the same time, the tread blank by the chamber 13 is pressed into the annular mold 1, and when the cavity is evacuated, the tread 28 is formed with a predetermined tread pattern. After that, the air from chamber J3 is exhausted and the drum 9 is removed from the annular mold 1. Then the tool 10 is introduced into the mold, using the shoes 14 of which the final protector of the annular tread is pressed and the step centering groove 29 is formed on its inner surface Fig. 3).
    The segments 17 and the supporting elements 18 of the drum for moving the belt are pushed to the complete tensioning of the band 19 in which the latter has the shape of an end (shown by the dotted line in Fig. 2) The outer belt 30 of the steel cord is formed on the band 19 to form a bracelet. After that, the drum is folded down reduce its diameter while keeping the perimeter of the bandage 19 and the belt layer 30 unchanged and injected into the annular shape 1. In shape 1, the segments 17 and elements 18 are moved radially outward to give the drum the original diameter. The first central step of the groove 29 is installed on the inner surface of the tread 28. Then, using a suitable means, the belt 30 is pressed in to remove air between the latter and the tread 28 and the inner surface 31 of the profile corresponding to the second step of the groove 29 is removed (Fig. A In the same way, the subsequent layers 32, 33 and 34 of the breaker are installed in the corresponding stages of the groove 29 with pressing out after installation with giving their inner surface a predetermined profile (figure 5). In this case, all layers of the breaker occupy
     position corresponding to their position in the finished tire and not shifted relative to each other thanks to
    the presence of steps in the groove 29. Then, annular linings 26 and 27 with an inner diameter D are attached to the annular mold 1, which create support surfaces for holding the sweeping rubber 35 applied to the inner surface of the tread 28 and the belt 34. Underbar rubber has a thin central and thickened marginal areas.
    After installing the underbrake rubber 35, the inner surface of the resulting belt and tread bracelet is shaped to match the bottom surface of the pre-assembled and molded tire carcass 36. The frame 36 is assembled by the method of flat Assembly without installing parts 37-40 side. Then, the frame 36 is molded to a toroidal for .1 with an arcuate diameter somewhat smaller than the diameter D, and set in the form I, the center of the belt-tread bracelet. Next, the framework of the frame 36 is to be molded to
    connect it with a belt-tread bracelet (Fig. 6). After the frame 36 is connected to the breaker-tread bracelet, parts 37-40 of the nose, heel and bead base are applied, which is shaped in their finished tire. Therefore, when assembling tires, these parts do not undergo any deformation. The ring covers 26 and 27 are removed from the mold 1 and the lateral parts 4 and 5 of the mold 1 are installed with the sidewall blanks 41 and 42 of the tire. The mold is evacuated to remove air and the sidewalls of the tire are molded. For fixing
    The sides of the tire are fitted with rings 6 and 7. Then Form 1 with the assembled tire is fed to vulcanization, after which the mold is cooled, disassembled and the finished tire is removed.
    During the implementation of the proposed method in the process of assembling the tire parts remain all the time in the same ring form 1, which is 66ec: i, - their reliable centering and
    prevents their deformation. In addition, the rubber and side parts acquire the required shape in the Goton Tire prior to assembly, which allows them to retain their shape more accurately and reliably after
    vulcanization pshny. All this leads to high quality tires with a multi-sided belt.
