Abstract
A mold gate for an inner tube mold is provided with a plurality of apertures for selectively receiving valve stems therein for bonding to the inner tube. A plug is inserted into each of the nonselected apertures to enable the single gate to be used to cure inner tubes having different valve positions to eliminate changing the gate each time a different valve location is required for a given mold. When the valve stem receiving openings are in close proximity to each other an elongated plug is placed in an elongated gate aperture to selectively seal one of the two valve stem openings while enabling the other opening to remain unblocked for receiving a valve stem during the molding operation.
