(under subclass 214) Apparatus having three or more pressure surfaces at least two of which are movable along paths in different directions and which act either simultaneously to co-compress the same material or sequentially so that one moving platen recompresses material compressed and held compressed by another moving platen.
(1) Note. This subclass includes wool press tables which have upwardly swinging hinged ledge leaves as one pair of platens. For such devices in which the leaves have means to carry with them a binder card, search this class, subclass 16.

42, for methods of pressing in which there are successive compressions from different directions.
215, for reciprocating platen presses of the box and piston type where there are means to place the material to be compressed on the means which supports the material during the pressing operation.
240+, for box and piston type presses in which a side of the box may be removable as on hinges but in which the movement of such side does not have a compressing function. SEE OR SEARCH CLASS
