A method for bending materials in a continuous manner with a bending machine having a fixed supply head and a movable bending head includes feeding material continuously along a material feeding direction through channels of the supply head and bending head, sliding the bending head in a cross plane perpendicular to the material feeding direction to adjust the bending head channel, and driving and swinging the bending head around a swinging axis that lies perpendicular to the material feeding direction to adjust the bending head channel. The feed amount of the material and a sliding amount and swinging amount of the bending head are detected and controlled. The bending head channel is thus adjusted and the material being continuously fed therethrough is bent. A method for bending hollow elongate material with a bending machine also includes feeding a mandrel along the feeding direction into a hollow in the elongate material. The head of the mandrel is detected and maintained at a head-detecting position and the material is bent with the movable bending head while being fed along the feeding direction. At a determined fairing time the mandrel is withdrawn along the feeding direction a predetermined distance away from the head-detecting position. Then, fairing the head of the mandrel is performed by cutting the head of the mandrel to a predetermined shape at a head fairing position aligned with the feeding direction, and the faired mandrel is refed along the feeding direction to the head-detecting position.
