Winding tube and method for the production thereof

摘要

The invention relates to a winding tube for winding up bands, films, sheets of metal or similar made of a spiral shaped wound metal strip whose adjacent strip windings overlap at least partially. The metal strip has a corrugated or ribbed profile in the cross-section thereof, whose external corrugated heads ( 1 ) are disposed on the outer wall of the winding tube after winding and are wider than the internal corrugated heads ( 2 ) disposed on the inner wall of the winding tube after winding.
