<p>Method for the renewal of the tread of a worn pneumatic or solid rubber tire. It consists in: applying a layer of bonding rubber to the exterior of a prepared tire body; imparting a very hard stretch to a prefabricated precured rubber tread ring to such an amount that its inner diameter is much greater than the diameter of the tire body to which it is to be applied and the tread rubber plastically deforms longitudinally to an extent that, upon being freed from the stretching forces, the tread rubber gradually reduces longitudinally down to a point of retaining a residual permanent stretch; freeing the tread ring from the forces employed in imparting the stretch; placing the freed previously stretched tread ring over the tire body while the tread ring that was very hard stretched to a large diameter retains temporarily an inner diameter greater than and in the range of the diameter of the tire body; leading away gaseous inclusions between the tire body and the tread ring, and heating the assembly of the tire body and the tread ring to vulcanize the layer of bonding rubber between the tire body and the tread ring.</p> |
