ABSTRACT:
A cold recapping method using a rubber bonding composition on each of a group of tires and a precured tread strip wrapped around each tire has each tire mounted on a rim and enclosed in a flexible curing envelope which extends radially inwardly over the sidewalls of the tire. The group of tires is assembled in side by side relationship with the envelopes held between the sidewalls of adjacent tires. End plates with resilient elements are applied over the exposed outer wall of the tire, at least at each end of the group whereupon each tire in the group is inflated to a low pressure to achieve the normal shape of each tire, the group on the holding mandrel is introduced into a heating chamber, the space between each tire and the envelope enclosing such tire is vented to atmosphere, each tire is inflated to a relatively high pressure so that the tires in the group press the radially inwardly extending portions of adjacent envelopes tightly together and against the adjacent tire sidewalls while the group is firmly retained together by the holding mandrel under axial pressure controlled by the resilient elements and the chamber interior is heated to a temperature less than 212.degree. and pressurized to a pressure somewhat lower than the high pressure within each tire.
