ABSTRACT:
A splice between ends of precured tread material is effected by establishing a gap between the ends that are to be spliced together after the tread material has been fitted to the buffed area of a tire with a cushion layer of uncured rubber between the material and the buffed area. The gap is established without compressing the tread material adjacent the gap and is approximately three-sixteenths of an inch and is filled with natural rubber using an extruder gun in a manner flushing air from the gap. The tire is then cured by heat and pressure for the necessary time required by the particular curing process employed.
