Abstract
A method and apparatus for bonding a carcass for a tubed tire with a belt band that protects the radially inner side of the tire. The bonding surface is coated with a rubber solution, the belt band is placed thereon, and the bonding zone of tire and belt band is vulcanized. To achieve an increased resistance to separation between a biased carcass and a belt band, the zenith portion of the tire is reinforced with additional or overlapping plies in such a way that the rigidity of the outer half in the circumferential direction is greater than that of the inner half. While avoiding high speed accelerators, the rubber solution is provided with such a quantity of polymerizing agent that at the selected vulcanization temperature a vulcanizing time of between a third of a minute and ten minutes results. The tire, which is provided with the belt band and is in a position of use, is disposed onto a ring that is provided with a circumferential trough and is heated. The tire is inflated to shrink its circumference and to compress the bond that is to be vulcanized with the belt band.
