DEFINITION

Classification: 264/109

(under the class definition) Processes directed to bonding to each other individually distinct particles which are associated randomly by bulk handling or deposition to form a layer containing a major amount of the particulate material.

(1) Note. The relative sizes of the particles are immaterial, however the particles must retain their discrete nature during the associating and bonding operation. Further, the mere presence of particles in a liquid carrier is not sufficient for this subclass (e.g., fillers or slurries), this being considered to be the molding of a fluent or liquid mass rather than the association of particles and is provided for in appropriate subclasses below.

(2) Note. The material is usually but not necessarily in the form of fibers or granules and bonding of the particulate material may be effected by applying an adhesive or by the latent adhesive characteristics of the material.

SEE OR SEARCH THIS CLASS, SUBCLASS:

6, for processes of forming solid particulate material by liquid or melt comminuting combined with uniting of said bulk assembled or deposited particles.

91, for processes of applying vacuum or suction to bulk assembled particles. 131, for a molding process combined with a step of coating with particulate material.

239+, for processes of molding (1) plastic compositions containing particulate material as a filler; (2) colloidal or nonsettling dispersions, e.g., rubber latex or clay; and (3) plastic particulate material which lose their identity during molding to form a homogeneous product and see (1) Note above.

19, Textiles: Fiber Preparation,

144+, for a process of bringing particles together, for example by air laying, and see the notes in subclasses 144+ for the line between this class (264) and Class 19.

23, Chemistry: Physical Processes,

313+, for agglomerating processes provided for in that class.

44, Fuel and Related Compositions,

550+, for a solid fuel consolidation or shaping process which goes beyond mere molding of a starting composition, especially subclasses 596+ for a process which includes pressing using a specified condition or technique.

51, Abrasive Tool Making Process, Material, or Composition, for a process of making an abrasive tool, material, or composition for abrading purposes. Also see "Search Class'' under the definition of Class 51 for related fields of search for preparing abrasive material stock.
