ABSTRACT:
A press of pressure cell type includes a press body part. The press body part comprises a number of plates with the planes of the plates oriented parallel to the planes of the adjacent plates. Each plate has a through hole which has the same center axis as the hole of the adjacent plates. Prestressing bands which induce a compressing prestress acting in the planes of the plates are arranged on an external edge surface of each of the plates.
