Abstract (en)

[origin: EP0402927A2] The invention proposes a method and an apparatus for bending flat metallic material, such as a structural steel mat, it being possible to clamp the material to be bent firmly between a support (12) and a holding element (14), which can be lowered. A bending element (16) such as a bending rod, then acts on the material in order to bend it to the desired geometry. The holding element (14) can be pulled out laterally from a bent shape. <IMAGE>
