ABSTRACT:
The invention provides a method of bending a sheet metal piece by means of a bending apparatus. The bending apparatus comprises a bending bar, a bending bar holder, a bottom die comprising an adjustable die bottom and a bending bottom die holder. The method of the invention is particularly suitable for bending sheet metal pieces which are shorter than the bending bar and the bending bottom die. In order to compensate for irregularities during the bending, the regions of the bending bar and bending die, respectivley, which are not influenced by the reactive forces of the sheet metal piece to be bent, are under the influence of compensating members bridging the air gap resulting between bending bar and bending die. Thus, the bending press is evenly loaded and the sheet metal work piece can be bent into an exactly predetermined bending angle.
