ABSTRACT:
A composite of a flexible, releasable backing having discrete portions of thin, sulfur vulcanizable, carbon black filled adhesive rubber composition thereon is used for adhering a tire tread splice and other applications in assembled rubber articles. The adhesive composition comprises a rubber composition containing a sulfur curative together with carbon black, processing oil, and tackifier resin. The invention is further directed to a method of preparing a tire having tread ends joined together with said discrete adhesive composition. The adhesive is applied to the tread from its releasable backing so that tacky adhesive need not be physically contacted by an operator or machine.
