Abstract

A lubricating system indirectly applies a bladder release agent to a green tire and cures the green tire in a tire curing machine. The system includes a deposition device and a curing bladder. The deposition device directly applies bladder release agent on to a deposition bladder. The deposition bladder is inflated within the green tire in order to deposit the bladder release agent on to an inner surface of the green tire. The curing bladder subsequently receives the green tire with bladder release agent deposited therein and cures the green tire.
