DEFINITION

Classification: 264/241

(under subclass 239) Processes in which different materials, portions or parts are brought into association and united by a mechanical shaping or molding operation.

(1) Note. For location in this subclass the product of such process must be: (a) the result of joining preformed parts with reshaping at the joining areas without destroying the identities of the preformed parts, (b) the result of placing one preform in a mold and adding fluent material, of different character or, (c) composed of clearly defined layers or parts. Resin impregnated felted batts assembled and pressed together to form a homogeneous article, for example, would not be placed in this or indented subclasses unless the patent clearly set forth that the product includes a line of demarcation between the layers. Woven layers, however, by their very nature, maintain their identity as layers when pressed together and would be included.

31+, for processes of forming composite in situ installations.

45+, for composite article making including a pore-forming step.

112+, for processes of forming stratified or layered articles by uniting of discrete, bulk assembled particles.

171.1+, for processes of forming continuous or indefinite length articles which are transversely stratified or plural element containing. 305, for processes in which a shaping surface is successively dipped into the same material.

642+, for processes of forming a multilayered, impregnated, or composite structured product by firing, sintering, or vitrifying of a shaped inorganic preform outside of a mold.
