(under the class definition) Apparatus in which the material to be treated is held between two opposed members which are movable or expansible towards one another to press or retain the material, and away from each to release the material. Usually at least one member is a fixed bed supporting the material.
(1) Note. Opposed conveying, feeding or discharging means which may apply pressure to the material conveyed are not here, but are with the appropriate type of apparatus; see particularly subclasses 110+, for external drum type, and the various subclasses under subclasses 201+, particularly subclasses 203+.
(2) Note. For devices wherein an absorbent member claimed as such contacts an article to be dried, see this class, subclasses 95+ and for other drying combined with absorbing, see subclass 71 and for spacing sheets or webs by alternate spacer sheets or webs, see subclass 94.
(3) Note. For driers combined with expressing or wringing, see this class, subclass 70.
(4) Note. For textile washing and wringing presses, see Class 68, Textiles: Fluid Treating Apparatus, particularly subclasses 94 and 241 and their indented subclasses.
(5) Note. For baling, expressing, copying, packing, and bundling presses, see Class 100, Presses, particularly
subclasses 211+ for presses having a flexible or deformable pressure surface, and subclasses 214+ for reciprocating platen presses not elsewhere provided for. (6) Note. For similar treating presses, see Class 144, Woodworking, subclasses 256.1+.
(7) Note. For heat exchanger platens, per se, see Class 165, Heat Exchange, subclasses 168+.
