DEFINITION

Classification: 156/379.8

With means to assemble laminae or position them relative to each other:

(under subclass 379.6) Subject matter including a mechanism for handling separately the laminae to be bonded, for holding them in an offset relation during bonding, for overlapping edges of a single lamina, or holding the edges in overlap, etc..

(1) Note. A mechanism for merely holding work in place does not qualify a patent for classification in this or its indented subclasses. The criterion to be applied is as follows: If the claimed mechanism calls for no more elements than can be used to heat, compress, mold, etc.., a single article or layer of material, it is not classified in this or indented subclasses, even though only a portion of the article or material is thus treated.
