Abstract
A method and an apparatus for forming a tube from a flat tape, more particularly for forming a shielding tape around a cable core, is disclosed. The tape is moved longitudinally along a straight path and simultaneously deflected laterally from a flat to a circular configuration around a mandrel, and the center of the tape is stressed over an eccentric ring attached to the outside surface of the mandrel in substantially inverse proportion to the stretch imparted to the tape during forming of the tube.
