<p>A method of vulcanising a green tyre, characterised by the steps of positioning a green tyre (1) over a bladder (5) supported by an upper ring part (6) and a lower ring part (7) in such a manner to be concentric to each other, lowering said green tyre (1) to a position where the horizontal centre line of the green tyre (1) corresponds to that of the bladder (5), lowering said upper ring part (6) to the upper end portion of the green tyre (1) and raising said lower ring part (7) to the lower end portion of the green tyre (1), expanding the bladder (5) to closely contact the inside of the green tyre (1), simultaneously lowering the upper ring part (6) and the lower ring part (7) by the same amount until the lower ring part (7) abuts a fixed lower mould (4), and lowering a movable upper mould to close the mould. <IMAGE></p> |
