PRODUCTION OF PNEUMATIC TYRE Russian patent published in 2014 - IPC B60C5/14 

FIELD: transport.

SUBSTANCE: invention relates to the automotive industry. The proposed process of a pneumatic tyre production comprises moulding of the tyre uncured blank 2 and curing. Here that said uncured blank 2 is fitted in a mould 3 and cured therein. With the blank 2 fitted in the mould 3, side strip rubber edge E that makes a boundary section between a bead strip 13 and rubber 12 extending to the blank outer surface 2a is located on the more inner tyre side in the radial direction than an inner point P1 of the tyre ring. The said point makes the intersection point between an outer surface 2a and an axial line L1 extending through the bead ring 7 on the tyre inner edge in the radial direction. An outer edge 15Bo of a bent edge 15B of insulation rubber 15 extends between a bent part 9b of a carcass ply 9a and the bead rubber 12 and is located from the more outer side of the tyre in the radial direction than an edge E of the bead rubber.

EFFECT: longer life of the tyre due to the decrease of hollows formation near the bead rubber is achieved.
