1. Method for obtaining an initially stressed press casing, in which the casing elements are initially connected disjoint, characterised in that the casing is then wound up with wire of temperature higher than the temperature of the casing elements, embracing with thus prepared coil all its elements, at the same time connecting the ends of the coil with each other and/or with the casing, followed by equalization of wire and casing elements temperatures.4. Initially stressed press casing, consisting of a bottom head, top head and side pillars, characterised in that the heads (1, 2) and the side pillars (3, 4) have on their outer side oblong cavities, which form a groove (5), in which the pre-stressing wire (6) is placed.<IMAGE>
