DEFINITION

Classification: 100/315

Reciprocating platen-type press:

(under subclass 305) Apparatus wherein the means for subjecting the material to compressive force includes a material contacting rigid planar surface and means to move the rigid planar surface towards and away from the material.

SEE OR SEARCH THIS CLASS, SUBCLASS:

214+, for a reciprocating press without the heating, cooling, or drying means.

295, for a platen or pressure surface.

300+, for a platen press for a brake assembly.

62, Refrigeration, for an apparatus for removing heat from a

substance by a change of phase of the coolant or refrigerant, especially 341, for a device for making a congealed product having a shaping press.

99, Foods and Beverages: Apparatus,

372+, for cooking apparatus having two imperforate movably connected heated plates or mold which confine and contact food material there between including waffle irons and sandwich grills.

144, Woodworking,

256.1+, for a wood bending press, especially subclasses 256.3+ for a wood bending machine which includes a platen press and a heating device for drying the wood in its bent form.

156, Adhesive Bonding and Miscellaneous Chemical Manufacture,

498, for a laminating device having cooling means and subclasses 580+ for a device for adhesively bonding comprising a specialized laminating press, especially subclasses 583.3 and 583.9+ for a platen press.

219, Electric Heating, the generic class for electric heating devices, especially

243+, for an electrical heating means combined with a nominal press (e.g., electrically heated iron, etc.) where no significant structural details of the press or article being pressed are claimed.

425, Plastic Article or Earthenware Shaping or Treating: Apparatus,

200+, for a mixing or kneading device upstream of a plastic or article former, especially subclass 208 wherein the kneading device is in the form of a helix.
