  • Crimp joints or seams are used in many areas of technology. For example, it is known to provide seaming in household appliances. For example, seam joints are provided in the casing walls of laundry drums. The problem, however, is that a quality of seaming, which are manufactured by means of manufacturing processes according to the prior art, is almost not verifiable. However, this is particularly desirable for rabbet joints that are exposed to high loads. Such high loads can occur, for example, in laundry drums during a spin operation. In order to make a folding connection of a laundry drum particularly stable, EP 0 395 859 A1 proposes to provide the folded seam with a plurality of beads oriented transversely to their course.
