Abstract:
1. A method of forming a run flat tire support, the method comprising: a. placing and contacting a unitarily moveable mandrel within a first mold body; b. contacting and fixing a second mold body to the first mold body and mandrel wherein the mandrel, first and second mold bodies form a mold cavity in the shape of a run flat tire support, and further wherein said mandrel engages both the first and second mold bodies such that when said mandrel is locked to the first mold body, the mandrel remains with the first mold body when the first and second mold bodies are separated and when said mandel is not locked to the first mold body, the mandrel remains with the second mold body when the first and second mold bodies are separated; c. introducing a polymeric material into the mold cavity to form the run flat tire support; d. selectively locking said mandrel to said first mold body; e. separating the first and second mold bodies and removing the run flat tire support, wherein said mandrel remains with the first mold body if said mandrel is locked to the first mold body, and said mandrel remains with the second mold body if said mandrel is not locked to the first mold body.
