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.

Abstract: A method for constructing an elastomeric composite ply comprises using parallel S and Z twisted cords to reinforce an elastomeric matrix. The S and Z cords are made inexpensively by using a yarn twist that is less than the cord twist. Composite plies made by the method can be used in elastomeric articles such as tires.

Abstract: High modulus reinforcement is used to make a radial ply pneumatic tire having only one carcass ply, i.e. a monoply tire. Poly-ethylene naphthalate (PEN) reinforcement is prepared in a manner that provides sufficient strength whereby the monoply tire can be made having reduced weight (as compared to a two ply tire) while having comparable durability, some improved handling, reduced rolling resistance, and improved flatspotting properties.
