Abstract (en)
[origin: US7661286B2] A method for the production of a cup-shaped article, in particular a blank of a screw cap for glass bottles or the like, from an enameled metal sheet, using two tools in a stepwise manner: 1) the blank is stamped from the metal sheet in a first tool by the relative motion between a cutting bell cooperating with a blank holder and a drawing block, and the blank is drawn around the drawing block, the width of a flange forming between the cutting bell and the blank holder being continuously reduced with a progressive degree of deformation until the flange reaches a defined width (R-r), and 2) the blank is deformed in a second tool such that the radially outwardly directed flange is deflected toward a profiling introduced in a wall of the blank.
