Abstract
According to the process for reconditioning the worn tread of a solid or inflatable tyre, wherein a prefabricated rubber tread is applied by vulcanisation of a binding rubber layer between the tread and the carcass to the latter, the damaged belts of the tyre carcass may also be replaced at the same time. The belts coated with rough rubber, for manufacturing new tyres or for a tyre reconditioning process which have to be carried out at high temperature and pressure conditions, are treated with an activator solution appropriate to the binding rubber. The rough rubber coating of the belt is so transformed that the belt material may be applied with a binding rubber inclusion to replace the damaged belt on the carcass and it may be vulcanised with the layer structure of the tyre blank used to the reconditioning in an over-pressure chamber at a temperature of about 50-95<o>C and at a pressure of 5-6 bars approximately. The belts fabricated according to this process may be used as a base material for manufacturing repair patches.
