V. C

The invention relates to equipment for assembling pneumatic tires and similar products, and can be used in the tire industry for transporting tire parts, in particular, belt-tread bracelets.

The aim of the invention is the possibility of providing a secure grip of belt and tread bracelets of various diameters.

In Fig.1 schematically shows the proposed device, a longitudinal section; figure 2 - view And figure 1} on fig.Z - location of the ribs on the elastic sheath; figure 4 - the proposed device, the working position.

The device includes a housing 1 with flanges 2, an actuator 3 for moving it, an elastic sheath 4 with sides 5 formed in central section 6 and side 7 in inclined annular sections and fixed with its sides 5 on flanges 2. Case 1 has means 8 for feeding the worker agent into the cavity of the elastic shell 4. The device is provided with uniformly installed along the entire inner surface of the elastic shell 4 stiffening ribs 9, located on the central 6 and lateral annular 7 sections and fixed with its end mi 10 bazkdu corresponding flanges 2 and sides 5 of the elastic sheath 4.

The device works in the following way.

When fed into the elastic sheath 4 of the working agent (compressed air) through the means 8, the shells begin to inflate due to the zones located between the ribs 9.

The webra 9 stiffness in the shell 4 are places where the folds are formed, since the ribs 9 are arranged at regular intervals, the dimensions of the corrugations 11 formed between these warehouses

Kami will be the same. The most convex part of the surface of the corrugation 11, which will be located symmetrically relative to the ribs 9 of the formed corrugations, will be covered and retained by the protective tread bracelet 12 (figure 4). The formation of the corrugation 11 on the surface of the elastic membrane 4,

10 facing the belt-tread bracelet 12, occurs at a higher pressure than that needed to obtain a natural shell shape. This causes greater rigidity.

15 of the elastic sheath 4 in a working condition, eliminating the influence on its shape of jolts during the transfer of the bracelet. The pressure in the casing 4 can be influenced by the amount of the corrugations 11, which determine the transfer diameter, which, in turn, makes it possible to transfer belt and tread bracelets of various diameters. Then the cycle repeats.
