Abstract (en)
[origin: CN114850316A] The invention relates to a method for producing a housing wall for a laundry drum for a household appliance for caring for laundry, comprising the following steps: providing a metal plate; forming the metal plate into a hollow cylinder; an expansion region which protrudes radially outward is produced in the hollow cylinder, the expansion region being produced completely around the longitudinal axis of the hollow cylinder, and the edge of the expansion region which surrounds the longitudinal axis being produced at a distance from the hollow cylinder edge of the hollow cylinder, an annular edge strip of the hollow cylinder is formed between the edge of the expansion area and the edge of the hollow cylinder; producing at least one molded structure having a plurality of molded elements in the expansion region; at least one compensation profile is produced in the edge strip and/or in a conical section of the expansion region in order to locally adapt the height of the edge strip determined in the axial direction.
