METHOD AND DEVICE FOR MAKING VEHICLE WHEEL TYRES WHICH CAN PROVIDE FOR MOVEMENT IN DEFLATED STATE Russian patent published in 2008 - IPC B29D30/20 B60C17/00 

FIELD: transportation.

SUBSTANCE: method for making the tyres lies in making frame structure on main cylinder, consisting of at least, one pair of ring shaped reinforcement insertions from elestomer material separated from each other, and at least, framework layer. The framework layer is joined on the periphery to the ring shaped reinforcement insertions. The frame structure also consists of at least, one pair of ring shaped fastening structures, joined to at least, one framework layer. The frame structure is given a toroidal shape and joined to the breaker structure, consisting of at least, one breaker layer, with a frame structure. When making the frame structure, there is formation of ring shaped reinforcement insertions on at least, one auxiliary cylinder. The ring shaped reinforcement insertions are taken from the auxiliary cylinder to the main cylinder until the framework layer is laid. Each reinforcement insertion is formed by winding at least, one continuous elongated element made from elastomer material for making coils, located one after the other on the auxiliary cylinder. The device for making tyres has a main cylinder, shaping device for giving the frame structure a toroidal shape, at least one auxiliary cylinder, apparatus for making ring shaped reinforcement insertions, and a transmission device for moving the ring shaped reinforcement insertions from the auxiliary cylinder to the main cylinder. The device has at least one, feeder for feeding the continuous elongated element made from elastomer material. The auxiliary cylinder is made with provision for rotation for winding the continuous elongated element. The transmission devices for the ring shaped reinforcement insertions have at least, one ring shaped transmission element and clamping members.

EFFECT: increased output and quality of obtained product.
