DEFINITION

Classification: 264/261

(under subclass 259) Processes in which two distinct preformed bodies with opposing surfaces are positioned in a spaced relationship with each other and a fluent molding material at least partially fills the space between the preforms said molding material acting to unite the preforms and being contained at least in part by said preform surfaces.

(1) Note. The fluent material here is introduced primarily for the purpose of filling or partially filling the space between the preforms, with any material which extends beyond the space between the preforms being of insufficient quantity to cover or embed the preforms except, at most, in the areas immediately adjacent the space between the preforms.

SEE OR SEARCH THIS CLASS, SUBCLASS:

277, for processes wherein plural spaced bodies are embedded in or surrounded by shaping material in which the shaping material, while it may function to unite the plural shaped bodies, does more than merely fill the spaces therebetween, but also gives the final article its outer shape or structure, at least in part.
