ABSTRACT:
Novel methods for sealing a closure member to a substrate make use of pressure generated in a chamber to create and/or maintain a seal between a closure member and a substrate. The chamber has a flexible wall which is urged towards the substrate by the pressure. Where the substrate has a hollow interior which is maintained at superatmospheric pressure, e.g. a pressurized telephone cable, a fluid passage is preferably provided between the interior and the closed chamber after the seal has been formed, thus taking the closure member out of peel with the substrate. A preferred closure member is an inflatable bag which has sealing material on selected portions of one surface thereof, so that it can be wrapped around the substrate to form a hollow enclosure around the substrate. After placing a restraining means around the wrapped closure member, the closure member is inflated, thus improving the seal around the enclosure.
