ABSTRACT:
Apparatus and methods for compressing a mass utilizing a plurality of interfitting anvils mounted for movement relative to one another along co-planar paths and include faces which, when the anvils are operatively moved relative to one another, exert compression on a mass positioned between the faces in at least two directions in a plane simultaneously. The faces of the apparatus can be so shaped that the cross section of the mass being compressed is urged toward a shape other than that of a regular polygon. Methods of the invention include the consolidation of a mass of compactable material enclosed within a hollow tube having deformable walls, the extraction of juice or oil from fruit or seeds and the internal fracturing of solids so as to swell materials such as solid rocket propellants.
