Abstract
A method of curing spokes is provided in which first molds of a first and second series of molds are placed into a platen press, and force and heat applied. The platen press is opened and the first mold of the first series is moved relative to the platen press while the position of the first mold of the second series is kept the same relative to the platen press. Force and heat are applied to the molds. The platen press is opened, and the first mold of the first series is removed while the second mold of the first series is kept within the platen press. A cured spoke is removed from the first mold of the first series.
