Method and apparatus for forming an apex

A method for forming a composite apex, the method comprising the steps of:

• forming a coextruded strip of a first compound and a second compound, wherein the second compound is a compound different than the first compound, wherein the composite apex is formed by winding the coextruded strip onto a rotatable platen, wherein the rotatable platen has a radially expandable bead chuck located on a radially inner portion of the rotatable platen, wherein the rotatable platen has an outer surface having a nonstick coating, and wherein the outer surface further includes one or more standoff bars, wherein the one or more standoff bars are flush with the outer surface of the rotatable platen in a first position and nonflush when the rotatable platen is axially retracted in a second position.
