Abstract

The invention relates to a method for forming a curved corner wall part (4c) on a baseplate (19), the curved corner wall part (4c) extending along a line of rounding (18) of the baseplate (19) and merging, at each end, into a side wall part (4a, 4b) which is formed on the baseplate (19). The method comprises the following steps: forming at least two side wall parts (4a, 4b) on the baseplate (19) by turning up an edge region of the baseplate (19) through an angle of substantially 90 DEG along a bend line (7a, 7b), which side wall parts (4a, 4b) extend as far as the corner region (5) of the baseplate (19) and merge into one another, in the corner region (5), via a crease-like transition (10) which is directed outwards, deforming the crease-like transition (10) and a part of the corner region (5) which adjoins the crease-like transition (10) to form a conical spout (10a) which extends along the line of rounding (18) of the baseplate (19) and along a section of the bend lines (7a, 7b) which adjoin the line of rounding (18), fitting a die (13) and a blank holder (16), which are substantially shaped so as to correspond to the conical spout (10a), around the conical spout (10a), and deep-drawing the conical spout (10a) so that the curved corner wall part (4c) is formed, the die (13) and the blank holder (16) preventing creases from being formed in the conical spout (10a) during the deep-drawing. <IMAGE>
