Abstract
An improved container is formed by attaching plates to outer side surface areas on opposite end portions of a liner with adhesive. The liner is supported for rotation about an axis which extends through the end portions of the liner and through the plates. The liner is rotated under the influence of torque transmitted to the liner through at least one of the plates and the adhesive attaching the one plate to the liner. Flexible material, which may be strands of continuous glass fibers impregnated with a thermosetting resin, is wound around the liner. As the flexible material is wound around the liner, the flexible material is wound over the plates at the opposite end portions of the liner. The surface areas, to which the plates are attached at opposite ends of the liner, are free of openings to the interior of the liner.
