ABSTRACT:
The invention relates to a bending apparatus for bending a rod-shaped or ribbon-shaped material, comprising a bending station disposed in a work plane and including at least one bending core or pair of bending cores mounted for displacement perpendicular to the work plane, and at least one rotary body carrying a bending finger mounted for rotation about the bending core and for displacement perpendicular to the work plane. With known bending apparatus it is scarcely possible to vary the bending mode, or the bending radius, respectively, without time-consuming adaptation of the bending station. Such adaptation may be required several times for a single workpiece. In accordance with the invention, the bending core or pair of bending cores is mounted, together with at least one further bending core or pair of bending cores for selectively employ in a bending operation, in a turret head mounted above the work plane for rotation at least to several operating positions. This permits the bending apparatus to be rapidly readjusted during the process of one and the same workpiece.
