Abstract
The invention relates to a method for wrapping a long or round part, for example a steel part, for instance in the form of a steel strip coil, a steel wire roll or a round steel part such as a roller bearing ring, the steel part being wrapped in a stretch film, in particular a plastic stretch film, in a helical and covering manner. In order to realize a short term wrapping of a long or round part, irrespective of its material properties, and as a reliable transport protection the invention proposes that a strip material which is significantly more resistant than the stretch film and has an adhesive coating on the side facing the stretch film is wound over the stretch film likewise in a covering manner.
