Abstract (en)
The present invention relates to a method for the dry pressing of a material in granular or powder form, to a device suitable to be used to perform pressing. The device includes: a bed plate (14); a movable body (10)for supporting a mold; a plurality of vertical rods (15)which engage the movable body from below; a supporting member (17)for supporting the rods; and a movement member (19,20) for vertically moving the supporting member. The method includes feeding liquid at low pressure to cylinder and piston assemblies (28, 29)which support the rods, closing a flow control means in order to prevent the escape of the liquid, and actuating a movement member in order to lift the movable body (10). <IMAGE>
