Abstract
Abstract A measuring system on a press for making pressings from powder material is designed for cutting out the effects of any stretching of the press frame produced by high pressing forces. A plate supporting one tool part is fixedly supported on a frame and, in relation to the plate, further tool parts may be moved. The measuring system is made up of first measuring elements fixed in relation to the moving tool parts, and second measuring elements, designed for use with the first measuring elements and fixed in relation to the press. The first measuring elements are fixed to the plate or a support on which this plate is itself supported.
