Abstract (en)

[origin: EP0844033A2] The bending machine (1) has a drive system (6). It has two separate bending heads which have workpiece support rollers (20,21) and at least one bending head is movable in a longitudinal direction. The travelling bending head (2) has circular or segmental formers (4a-4c,5), and pivots about an axis (40) fixed to the fixed bending head (3) which has peg-type formers (11). Flexible leads (14,15) and quick-release couplings (8,13,17), transmit control signals and hydraulic or pneumatic power from the control unit (7) and power unit to the bending heads. The fixed bender has a chuck (30) mounted on a sliding track (35), so that the rotational and linear fed position of a workpiece (31) can be adjusted. The power unit can be located on either bender.
