摘要： A press apparatus for producing dimensionally accurate pressed articles from a particulate material including a frame (70, 73), which can be connected via respective lower and upper connecting devices (71, 72) to a lower and upper platens of a press, a die holding plate (5) arranged in the frame and preferably rigidly connected with the lower connecting device, in which the die holding plate is displaceable relative to a base body (0), a plurality of punch carriers (1-4), at least one of which is supported on the frame between the die holding plate and the base body so as to be displaceable relative thereto into charging and pressing positions by piston/cylinder drives, and supports (12, 22, 32, 42), which in the final press position support the punch carriers relative to the base body. The support of the punch carriers is improved by arranging the supports between the base body and the associated punch carriers such that in the final press position punches seated on the punch carriers are centrally supported in the line of the pressing force via the supports.
