DEFINITION

Classification: 264/301

(under subclass 299) Processes in which the molding material is applied in bulk to the molding surface causing a relatively small proportion to be deposited or adhered to the molding surface followed by relatively separating the mold

form with the adhering material from the remaining bulk.

(1) Note. This subclass includes, for example, pouring molding material into a mold and pouring out the excess which does not cling to the mold walls or dipping a mold form into the molding material and removal of said form therefrom with a coating of said material adhered to the molding surface.

SEE OR SEARCH THIS CLASS, SUBCLASS:

215, for processes of forming indefinite length or continuous articles wherein the molding surface, e.g., belt or wheel, dips into the molding material.

308, for incremental molding processes.

SEE OR SEARCH CLASS 162, Paper Making and Fiber Liberation,

228+, for processes of accreting from a bulk supply of pulp suspension.

430.1+, for processes of coating by immersion and see the class definition of Class 264 at section II F for the line between Classes 264 and 427.
