<p>A press (10) particularly for forming a blocklike tablet or compact from powder. A die (45) is split into opposed halves (54, 55) for defining a die opening (78) vertically therethrough. The die (45) is supported within a carrier (41) having an openable front door (48). The carrier (41) is mounted on a carriage (12) which is horizontally rollable on a base frame (23) between compacting and loading positions. The carrier (41) preferably has limited resilient floating movement relative to the carriage (12) in the vertical direction. A first pressure cylinder (61) has its housing (62) carried by the carrier (41) so that its piston rod (63) extends horizontally for direct compression against a rear side of the die (45). A second pressure cylinder (65) has its housing (66) mounted on the frame (11) and its piston rod (67) extending vertically downwardly for compression against a punch (74) which projects downwardly into the die opening (78) to compress the powders therein against a lower punch (72). The die (45) is vertically aligned with the piston rod (67) of this second cylinder (65) only when the carriage (12) is in the compacting position.</p> |
