ABSTRACT:
A processing mold is suitable for preparing a tire support. One processing mold that is particularly advantageous includes a processing mold having a first mold body opposing a second mold body, and the first and second mold bodies are aligned through a mandrel. In one embodiment, a first mold body includes a locking member suitable for locking the mandrel to the first body. In this embodiment, the mandrel is movable between the first and second mold bodies such that when a processing mold is opened, the first mold body and the mandrel can separate from the second mold body. A method of using a processing mold by aligning a first mold body and a second mold body through a mandrel and a method of releasing a tire support from a processing mold by locking a mandrel to a first mold body and separating the first and second mold bodies are also particularly advantageous.
