When the auxiliary core (18) and part (20) of the first shaping die (12) have been removed, the final can shaping process occurs, in which the second shaping die (14) likewise travels over the centre of the can.

According to the invention, the structural parts are produced using an embossing die (14) that comprises a matrix (16) and a two-part die (15) which consists of a fixing die (26) and a shaping die (27).

The round blank (10) can thereby be turned towards a stamp (23) or a forming die (24) with any one of its flat sides (13).

The invention concerns a method of bending workpieces (14) in which the actual value of the bending angle (β) is continuously determined whilst the workpiece (14) is released from the male shaping die (8) and/or the female shaping die (10).

The sides of a newly formed package are heat sealed through apertures (98) in the forming die (86) before the package is placed in the fixture.

Said working surface displaces the material differently in two transverse directions which are rotated about 90°.
