Abstract (en)
[origin: EP0872292A2] The machine is equipped with a bending head (50), which is accommodated by a movable slide (20), provided with a controllable drive. The slide is positioned on a plate (25), which is connected with an accommodation shaft (35) pivotably located in the machine frame (2) and effectively connected with a drive. The shaft is fitted on a displaceable carriage arranged in the basic frame of the machine. The carriage is effectively connected to a controllable drive. The plate has guides for the displacement of the slide and also has a screw spindle effectively connected to an auxiliary motor (31) and a threaded nut fixed on the slide. A number of machining units are arranged on the slide.
