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 (8), whereby the bending rolls (1, 2) are mounted rotatably about their mutually parallel longitudinal axes (10, 20) on a bending stirrup (3), which is situated with its length perpendicularly to the longitudinal axes of the bending rolls (1, 2). Each of the bending rolls (1, 2) is aligned with a means of a mutual forced rotary coupling of both rolls (1, 2) and at least one of the rolls (1, 2) is coupled to a drive of its rotation, whereby the bending stirrup (3) is mounted rectilinearly reversibly slidingly in the direction of its length in a rotary bending carrier (5), which is mounted in a bracket (6) rotatably about its longitudinal axis (50), which is parallel to the longitudinal axes (10, 20) of both rolls (1, 2) and is situated in a plane interlaid by the iongitudinal axes (10, 20) of both rolls (1, 2) and at the same time is perpendicular to the direction of the length the bending stirrup (3), the bracket (6) being mounted on the frame (0) of the bending head rectilinearly reversibly slidingly in the direction (X) perpendicular to the Iongitudinal axes (10, 20, 50) of both rolls (1, 2) and of the rotary bending carrier (5) and parallel to the direction of the length of the bending stirrup (3), all in a mutual initial position "zero" " during insertion and removal of the bent materia! into and from the rolls (1. 2). |
