ABSTRACT OF THE DISCLOSURE The invention relates to a machine for processing metal in sheet or plate form, and especially for bending metal sheets. The machine includes a machine frame structure with a table base and a ram vertically displaceable in relation to the table base. An upper tool is mounted on the ram and a lower tool is disposed on the table base. These two tools cooperate to perform the processing of the metal sheet. One of the tools is supported by an elastic support means or by an oil cushion to provide, directly or indirectly, an elastic or compliable supporting of the tool. Thus, either the elastically supported tool itself or a support member supporting the tool comprises a plurality of individual elements which are disposed tightly besides each other and are independently displaceable in a vertical direction so that, in operation, only those elements are displaced towards the supporting means on which the work-piece to be processed rests.
