ABSTRACT:
An isostatic press comprises a pressure vessel defined by a tubular jacket and by two end plugs. The jacket is, in the direction of its longitudinal axis, displaceble between two positions. The jacket surrounds a third plug centrally located between the two positions of the jacket so that, when the jacket is in one of its end positions, the central plug closes one end of the jacket, and vice versa. The two jacket positions alternatingly serve as pressing and charging positions so as to permit recharging of the press at one position simultaneously with carrying out a pressing operation at the other position. This arrangement approximately doubles the productivity of the press.
