ABSTRACT:
Renewal of the running surface of a worn pneumatic or solid rubber tire, in which a layer of bonding rubber is applied to the prepared body of the tire and to the interior of a prefabricated precured rubber tread ring has gaseous inclusions between the applied layers led away and the assembly prepared in this way is heated in an autoclave for vulcanizing the layer of bonding rubber. The tread ring directly before applying it to the body is stretched very hard in a simple stretching mechanism so that when the tread ring is removed from the stretching mechanism a free stretch of about three to four percent remains temporarily. This allows the freed but stretched tread ring to be slipped over the body without further auxiliary means retaining the ring stretched and the ring to be arranged in exact correlation with the circumference of the body. The free stretch rapidly and continuously reduces to about one percent permanent stretch. In any case the duration of the temporary free stretch, which is available after the stretching process is completed and freed, is adequate for applying the tread ring to the body of a prepared tire in a simple manner.
