PROCESS AND VULCANISING MOULD FOR MANUFACTURING TYRES FOR VEHICLE WHEELS Russian patent published in 2018 - IPC B29D30/06 B29C35/02 

FIELD: transportation.

SUBSTANCE: invention relates to a method for manufacturing tyres for vehicle wheels. Technical result is achieved by a method for manufacturing tyres for vehicle wheels, which includes building a green tyre having a symmetric profile in radial section, having a radially outer tread band, two radially inner beads and two sidewalls each being extended from one edge of the tread band to one of the beads. Method then includes moulding and vulcanising the green tyre, during moulding and vulcanisation, providing movement to the tread band with respect to the beads along a direction parallel to a rotation axis of the tyre. During vulcanisation, the tread band moved axially with respect to the beads is retained in accordance with an axially asymmetric position with respect to a middle line plane of the tyre, in such a way as to obtain a moulded and vulcanised tyre having an asymmetric profile in the radial section.

EFFECT: maintaining high technological flexibility and high productivity at existing plants, as well as increasing the stability of the tyre structure in accordance with the asymmetric configuration.
