DEFINITION

Classification: 162/100

(under the class definition) Processes, for depositing fibers from a liquid suspension thereof to form an interfelted fibrous product (paper), combinations of such fiber depositing steps with other treatments of the deposited fibrous product, treatments of the deposited product prior to the final drying thereof not otherwise provided for, paper

treating processes not otherwise provided for, and products of such processes not otherwise provided for.

(1) Note. In processes classified in this or indented subclass the fibrous nature of the product must be retained. Processes in which the fibers are converted to a nonfibrous form are classified in the appropriate material working class, e.g., Class 264, Plastic and Nonmetallic Article Shaping or Treating: Processes.

(2) Note. In this and indented subclasses the articles are usually classified with the corresponding processes, however, certain subclasses by their nature, as for example, those providing for various manipulative procedures, take only processes, the products being old or conventional or classifiable elsewhere on other bases.

(3) Note. Articles and materials provided for in other classes are not classified in this class (162) merely because they are made of paper (deposited fibers).

(4) Note. Indented subclasses (141-181) also, include the products under "E." of the class definition of this class (162).

SEE OR SEARCH THIS CLASS, SUBCLASS: 13, for processes of digesting fibrous material combined with forming a web or article from the liberated fibers.

232, and 252 to 411, 415 and 416, for apparatus for forming paper from fibrous materials.

29, Metal Working,

90.01+, for processes restricted burnishing or the combination of burnishing and calendering of a dried felted fibrous product.

34, Drying and Gas or Vapor Contact With Solids, appropriate subclasses, for processes restricted to drying of wet felted material by evaporation of the moisture contained therein.

100, Presses, for processes restricted to mechanically expressing liquid from a wet felted web, and processes for calendering a dried web, with or without the steps of moistening and/or drying, the steps of calendering, moistening and drying being taken in any order.

264, Plastic and Nonmetallic Article Shaping or Treating: Processes, appropriate subclasses, for processes under the class definition for forming articles from rewetted paper, see References to Other Classes in the class definitions of this class (162) and (1) Note above, sor a search note to Class 264.

427, Coating Processes, appropriate subclasses, for processes of coating paper not combined with a paper making step, or where the paper is not still wet from the paper forming operation, and for processes of coating dried felted fibrous material.

493, Manufacturing Container or Tube From Paper; or Other Manufacturing From a Sheet or Web, appropriate subclasses for making an article from finished paper.
