DEFINITION

Classification: 264/271.1

Preform embedded in or surrounded by shaped material:

(under subclass 259) Processes in which the preformed self-sustaining body has molding material shaped about it so that said body is surrounded by or embedded in said molding material.

(1) Note. Shaping of a molding material to a planar surface only if a preform is not within the scope of this subclass. To be placed herein, the patent must include confining the preform in two dimensions thereof with the shaping material so as to embed or surround the preform.

SEE OR SEARCH THIS CLASS, SUBCLASS:

35, for processes of forming structural installations in situ in which molding material is shaped around and united to a core or preform.
