Method of manufacturing a vehicle tyre having clamped turn-up's

摘要

Production of a pneumatic tire with a carcass (5) and a carcass end wrapped around cores (6) to form a wrapping layer, where the carcass is placed on a construction drum (1), the cores are placed on the carcass and the wrapping layer is formed using a bellows, involves (i) wrapping the cores, (ii) pressing the carcass end radially inwards and (iii) inflating the carcass so that the construction drum is radially expanded. Production of a pneumatic tire for a vehicle, including a carcass (5) and cores (6), around which a carcass end is wrapped axially and radially outwards to form a wrapping layer, where the carcass is placed on the casing surface of a construction drum (1), the cores are placed on the carcass and the wrapping layer is formed from the carcass end using a bellows located outside the drum, involves the stages of: (1) wrapping the carcass end around the cores so that the carcass end edge (9) lies horizontally on an axially inner carcass region; (2) pressing the carcass end radially inwards with a tool (11), so that the carcass end lies axially outwards and parallel on the axially inner carcass region and encloses the cores; and (3) inflating the carcass (if necessary together with other components), such that the construction drum is radially expanded.
