Abstract
The invention concerns an arrangement () and a method for the manufacture of can bodies from pot-shaped blanks (). To this end, the blank () is inserted into a bottom tool part (). The blank () is clamped between a downholder () and a counter support surface () of the lower tool part (). For controlling a position value α determining the position and/or position change of the downholder (), a drive arrangement () is provided. The drive arrangement controls the position value in accordance with a predetermined course, so as to move the downholder () into the clamping position or out of the clamping position EP. As soon as the downholder () reaches its clamping position EP, the drive unit () controls a force value in accordance with a predetermined course which determines the clamping force F(t) which is applied by the downholder () to the blank (). This occurs preferably by an adjustment of the motor current I to a predetermined course of the desired value I(t).
