ABSTRACT:
A thin, membrane-like cylindrical rubber tire curing bladder is provided with reinforcing cords wound in parallel spiral paths at any composite angle to the longitudinal axis of the cylinder. When installed on the centerpost mechanism of a tire curing press and inflated in the curing process, the bladder length increases due to partial and reversible straightening of the spirally wound cord reinforcement. This permits optimum fit of the bladder in the tire being cured with uniform controlled growth of the membrane. Longer service life of the bladder is thereby achieved. The bladder is a good heat conductor inherent to its thin matrix, unlike previously known curing bladders.
