ABSTRACT:
A machine for bending elongate material, more particularly tubular members such as brake lines, fuel lines or the like, includes a central clamping device for the elongate material. Bending heads are located on opposite sides of the clamping device, in opposite directions along the axis of the unbent elongate material. Each of the bending heads has a bending die and a counterpressure die that can be swivelled around the axis of the bending die. The bending heads can be moved independently of one another along the axis of the elongate material and can be swivelled around the axis of the elongate material so as to rotate the respective bending planes formed by the respective bending dies and counterpressure dies.
