<p>PURPOSE:To execute bending simply and easily in a bending device by which bending is performed continuously on a material to be worked. CONSTITUTION:The device is provided with a first rotary body 11 which is in contact with the inner side of a work 6 to be bent and is rotatably movable and plural second rotary bodies 12 which are set in contact with the outer side of the work to be bent in rotatably movable and set at prescribed intervals from the first rotary body; and the plural second rotary bodies are set at prescribed intervals from the body 11 and also made to approach the first rotary body 11 so that the work in contact with the first rotary body 11 is deformed into a bending state B from a straight state A.</p> |
