ABSTRACT:
In an automatic punching and bending machine the interspace between the bending device and the punching device is adjustable in order to make the interspace as small as possible and to adjust that interspace in dependence on the length of the working piece of a band material, thereby gaining the advantages that series of different work pieces of high precision can be produced in the same machine. The bending device is removable and can easily be replaced by another one which has been reset in a preceding working process. Therefore standstill periods of the machine are reduced.
