ABSTRACT:
A process for manufacturing a flexible cylindrical body includes the steps of providing a flexible preform of non-resilient synthetic material which is inflatable to cylindrical form, inserting the preform into an elongated coil of an electrically conductive material having a diameter relative to that of the preform in its inflated cylindrical form such that the preform is expanded in an unstressed condition into engagement with the inner diameter of the coil, the inner face of the coil being coated with an adhesive material, and applying a predetermined voltage to the coil to thereby fuse the adhesive material and connect the coil and preform.
