Description

one

The invention relates to methods for assembling elastic couplings, pneumatic tires and can be used in the tire industry, in particular, in assembling multilayer and multi-winged pads-5 tires of pneumatic tires.

A known method of manufacturing multilayer bracelets of pneumatic tires by successively superimposing one on the other and subsequent 10 duplicating them, in which the bracelets are applied by opening the outer bracelet until a ring is formed and the next bracelet is inserted into its cavity until it is fully adhered to previous bracelet l.

The disadvantage of this method is that it is intended only for assembling multilayered cylindrical bracelets of 20 cylindrical shape. This method does not collect rubber-cord product completely.

Another method of assembling rubber-cord products is also known, consisting of 25 in that they form the inner and outer rubber-cord bracelets, put the bead rings on, wrap the edges of the bracelets with the side panels, turn on the next layers of cord and non-30

crawled in accordance with the design of the product parts 2.

The disadvantages of this method are the low quality of processing of the boards of multilayer rubber-cord products.

The aim of the invention is to provide an assembly for a rubber-cord product with different sides in construction,

 The goal is achieved by iTO in the method of assembling rubber-cord products, which consists in forming the inner and outer rubber-lord bracelets, setting the side rings, wrapping the edges of the bracelets with the decoration of the boards, imposing the subsequent layers of cord and the necessary B according to the design of the part product according to the invention , first they put the side rings on the outer rubber bracelet, wrap the edges of the rubber cord bracelet on the side rings, and then set the inner rubber cord bracelet to ncentricio external, unclench its central part to contact with the inner surface of the outer rubber cord bracelet and wrap its edges on the outer surface of the outer rubber cord bracelet with the design of the boards.

Subsequent layers of the cord are applied to the outer surface of the outer rubber cord bracelet prior to the decoration of the beads.

FIG. 1-11 show successive stages of assembling a rubber-cord product by the proposed method; in fig. 12 - side structure of a rubber-cord product.

The method is carried out as follows.

They form an external rubber-cord bracelet, put side rings on it, wrap the edges of the bracelet with. design the sides, then form the inner rubber-cord bracelet, place it concentric with the outer bracelet, unclasp its central part until it touches the inner surface of the outer rubber cord bracelet and wrap its edges on the outer surface of the outer rubber cord bracelet with the sides design.

On the drum 1 form the outer multilayer bracelet 2 (Fig. 1). Then the middle part of the drum 1 is opened, and the side wings 3 are fitted on the bracelet 2 (Fig. 2). After landing the wings 3 produce: twisting of the bracelet 2 on the wing and putting on the hanging layers 4 (Fig. 3). A carrier 5 is pulled over the drum, which presses the frame bracelet b (Fig. 4) and removes it from the drum (Fig. 5).

Next, on the compressed drum 1, the inner bracelet 7 is assembled (Fig. B). The carrier 5 with the frame bracelet 6 is pushed onto the drum 1 (Fig. 7). Next, the central part of the drum 1 is expanded to complete connection of the cord bracelet 7 with the frame bracelet 6 (Fig. 8). Then the carrier 5 is retracted, the edges of the cord are wrapped; about the bracelet on the wing and layers of cord 8 are applied (Fig. 9). Then the carrier 5 is pulled over the drum 1, the resulting product is pressed together (Fig. 10) and removed

from the drum (Fig. 11) to obtain a multilayer product (Fig. 12).

The use of the proposed method makes it possible to assemble rubber-cord products with a large number of layers, with a complex conformation of the board, as well as to improve the quality of processing of the boards and to increase labor productivity.

Claims (2)

1. The method of assembling rubber-cord products, consisting in forming the inner and outer rubber-cord bracelets, putting the bead rings on, wrapping the edges of the bracelets with the decoration of the boards, imposing subsequent layers of the cord and necessary in accordance with the design of the product, details, and with the fact that , in order to ensure the assembly of a rubber-cord product with different sides of the design, first put the side rings on the outer rubber-cord bralet, wrap the edges of the rubber-cord bracelet on the side rings, and then install the inner rubber-cord bracelet concentrically to the outside, unclip its central part until it touches the inner surface of the outer rubber-cord bracelet and wrap its edges on the outer surface of the outer rubber-cord brace TcL with the design of the sides. . 2. A method according to claim 1, characterized in that the subsequent layers of the cord are applied to the outer surface of the outer rubber cord bracelet to the shape of the beads.
