Method and apparatus for improved tread splicing
Abstract:
A method of cutting a length of tire tread for a retread tire includes measuring a circumference of the tire casing and cushion gum, and dispensing a length of tire tread from a roll based on the measured circumference. The length of tire tread relative to a tread cutter is adjusted so that the tire tread design at the point where the tread may be cut is between a set of marks formed in the periodically repeating tread design. The tread is then cut along a linear length of the tread disposed within the marks so that the periodically repeating tread pattern appears substantially continuous across a seam defined when the section of tire tread is wrapped around the casing such that the first and second ends meet in abutting relationship.
