<p>The method produces pneumatic-, solid- or hollow tyres, in which the tread is moulded and pre-vulcanised separately. The tread and other components are assembled. Then, following vulcanisation the tread is removed from the mould. In the novel method, the tread is made in two (or more) separate axial sections, forming part-annuli (17) held by corresponding mould annuli (1). The annuli are moved together into contact, to unite the halves of the tread, working together with an internal sub-assembly, to complete tyre assembly.</p> |
