ABSTRACT:
A laundry drum is configured for high-speed spinning of damp linen. The drum has a rotating drum shell, which is curved from a thin-walled material strip to form a cylinder. The parallel end edges of the material strip contact to form a joint line. So that the drum may resist drum speeds higher than 1500 rpm, the end edges have a slot-shaped teething. The teeth and of the teething engage into the respective tooth gaps of the opposite end edge, so that the base lines of the tooth gaps meet to form an at least approximately straight line. The teeth are fitted into the non-toothed zone of the end edge outside of the drum above the material strip, each tooth being firmly secured to the respective non-toothed zone.
