Abstract

The subject invention includes methods and apparatus for joining treads. Such methods include the step of providing a first tread portion and a second tread portion for forming a joined tread, each tread portion comprising a section of tire tread extending lengthwise from a terminal end. Additional steps include providing a first fixture configured to retain the first tread portion and a second fixture configured to retain the second tread portion and securing the first tread portion into the first fixture and securing the second tread portion into the second fixture, each of the first and second fixtures being arranged within the first and second fixtures such that the terminal end of each tread portion is in communication with a joining side of each fixture. The methods further include directing the terminal ends towards each other and into forceful engagement with an elastomeric joining material arranged between the terminal ends.
