Abstract

The invention relates to a press for making dimensionally stable stacked pressed articles from a powdered material. The said press has a lower (16) and an upper pressing ram hammer with a basic body (1) which is fixedly supported in the press and in which there are arranged hydraulic annular piston systems (2, 3, 4) which are arranged one above the other. According to the invention, the basic body (1) is formed from a plurality of levels (1a, b, c) which are arranged so as to be situated at a distance from one another, and one above the other, while being fixed with respect to one another, each level containing at least one of the coaxial hydraulic annular piston systems (2, 3, 4). <IMAGE>
