Abstract
A cylindrical cavity is continuously contacted while removing a rigid liner from within the cavity. The supporting apparatus includes a flexible liner insertable within the rigid liner, having an expanded diameter greater than a diameter of the cavity, and having a top end and closed bottom end. A hollow conduit is attached to the bottom end of the flexible liner and has an opening adjacent the bottom end for introducing a fluid to expand the flexible liner against the cavity and contact the cavity as the rigid liner is withdrawn from about the flexible liner.
