Abstract
A method for manufacturing a tyre is provided, in particular a run-flat tyre. The method includes providing a drum with a first shrink section and a second shrink section. Each shrink section is provided with a shrink surface that is radially movable. The method includes moving the shrink surfaces radially inwards with respect to the central axis from a level position to a shrink position in which the drum, at the shrink surfaces, has a circumference with a second diameter that is smaller than the first diameter, while creating a partial vacuum between the shrink surfaces and a first tyre layer at the first shrink section and the second shrink section. The method further includes shrinking the first tyre layer onto the shrink surfaces in the shrink position under the influence of the partial vacuum. A drum for use in the aforementioned method is also disclosed.
