(under subclass 240) Apparatus in which any of the elements of the chamber, as the side walls or portions thereof, or a pressure surface which is stationary relative thereto during the application of compressive force to the material are movable relative to one another for purposes other than the application of compressive force to the material.
(1) Note. In these devices the box parts may be movable relative to each other, that is, the bottom of the box may be separable from the side walls or the side walls movable relative to the box bottom. Where the box is movable as a unit transversely to the direction of compressive force, search this class, subclass 229.
