ABSTRACT OF THE DISCLOSURE A machine for processing metal in sheet or plate form, especially for bending metal sheets. The machine comprises a frame with a table base on the frame and a ram which is vertically displaceable in relation to the table base. The ram has an upper tool, while a lower tool is disposed on the table base, these two tools cooperating to process the metal therebetween. The lower tool is elastically supported on the table base by means of a plurality of individual re- silient supports which are arranged in a row on the table base. A plurality of intermediate parts are inserted between the table base and the supports and said parts are displa- ceable groupwise out of the effective region of selected supports into a neutral position, so that only the supports lying directly under the workpiece to be processed are ef- fective.
