Abstract: A bending head for an automatic bending machine includes a frame. A first rotationally driven bending roll is arranged in the frame. A bending arm is transversely arranged below the first bending roll and is coupled to a bi-directional drive, with an end of the bending arm rotatable about the longitudinal axis of the first bending roll. A rotatable second bending roll is mounted to an opposite end of the bending. A bending support is configured with the first and second bending rolls. The second bending roll is rotationally coupled to the first bending roll in a forced torque transmission manner for mutual counter-direction rotation of the first and second bending rolls. The bending rolls have axially symmetric reduced lateral circumferential sections. The bending roll controls an angle of mutual rotation of both of the first and second bending rolls.

Abstract: The invention relates to a bending head, especially for an automatic bending machine, containing a pair of bending rolls (1, 2) and a bending support (3), whereby below the first bending roll (1) is arranged transversely on the bending head a bending arm (20), which is positioned with its longitudinal axis perpendicularly to the longitudinal axis of the first bending roll (1), the bending arm (20) is mounted on the bending head with one of its ends rotatably about the longitudinal axis of the first bending roll (1) and is coupled to a drive, while at the other end of the bending arm (20) is mounted rotatably about its longitudinal axis the second bending roll (2), whose longitudinal axis is parallel to the longitudinal axis of the first bending roll (1).
