The head (1) has holders (4a, 4b) movably supported on a carriage (3) against each other in a pull-out position. A bending core (13) comprises bending core sections, and bending fingers (12a, 12b) are arranged at holders and swivelable around the core sections on a circular curve type path. Middle points of the path are coincided with each other in the pull-out position, where the bending fingers are swivelable in the path. Drives (9a, 9b) i.e. numerical control drives, are supported at the holders. The bending fingers are designed as bending rollers or sliding pieces. |
