Abstract
A press particularly for forming a blocklike tablet or compact from powder. A die is split into opposed halves for defining a die opening vertically therethrough. The die is supported within a carrier having an openable front door. The carrier is mounted on a carriage which is horizontally rollable on a base frame between compacting and loading positions. The carrier preferably has limited resilient floating movement relative to the carriage in the vertical direction. A first pressure cylinder has its housing carried by the carrier so that its piston rod extends horizontally for direct compression against a rear side of the die. A second pressure cylinder has its housing mounted on the frame and its piston rod extending vertically downwardly for compression against a punch which projects downwardly into the die opening to compress the powders therein against a lower punch. The die is vertically aligned with the piston rod of this second cylinder only when the carriage is in the compacting position.
