Abstract:
A method of bonding an all-elastomeric valve onto the base portion of a metal-core valve in a conventional inner tube to give an inflatable elastomeric tube which can be inflated to any desired size outside of a confining casing, so it can withstand extreme stretching, elongation, deformation, and twisting.
