A METHOD FOR COMPACTING POWDERED, GRANULAR, OR PARTICULATE MATTER, AND FOR CONTAINING THE COMPACTED MATTER DURING SUBSEQUENT PROCESSING

摘要

This invention relates to a method for compacting powdered, particulate, or granular matter and for containing the compacted matter during subsequent processing. When a continuous tube woven of high-tensile strength material is subjected to an axial elongating force, its radius tend s to undergo a reduction proportional to axial elongation, and its included volume decreases. When su ch a tube in relaxed untensioned state is uniformly filled with other material and then subjected to an elongating axial force, the volume within the tube tends to reduce and the contained material is subjected to a compacting force. Axial elongating force may be maintained or varied during subsequent processing of the contained powder. The tube may be wound on a bobbin or other shape during further processing of the contained material. To fabricate very long continuous filled tubes, the tube may be woven in the region surrounding a nozzle through which the contained material is extruded at a uniform rate, Since the tube is woven; small apertures exist through the tube wall through which other substances m ay be introduced or extracted
