Abstract

A bending machine (1) is provided wherein components of the existing abutment system, namely a drive part or a carriage (7), which can be directly or indirectly detachably coupled to the lower tool, are used instead of an additionally integrated device (axle) for displacing lower tools (2) transversely in relation to their length. In this way, the existing axle of the abutment system can also be used to adjust the tool.
