ABSTRACT:
A tire curing press has a cross beam that carries the upper mold section and is moved to open and close the press. When the press is closed, a cross beam locking mechanism located in the middle of the cross beam holds the cross beam to the tire press base that carries the bottom mold section. The locking mechanism prevents bending or bowing of the cross beam which would otherwise adversely affect the quality of the tires produced in the press.
