Bending apparatus for a long material

A bending apparatus for an elongated material comprising:

• a supporting device for holding the elongated material in a cantilever fashion so as not to slide the elongated material in a longitudinal direction thereof;
• a bending device which nips the material at an input point apart from the supporting device and is rotated by a predetermined angle so as to bend the material between the supporting device and the input point;
• a driving device for rotating the bending device;
• a feeding device for moving the material toward the bending device and setting a position of the material;
• and
• a moving device which sets up a separation distance between the supporting device and the bending device prior to bending of the material and allows the supporting device and the bending device to move relatively during the bending of the material.
