DEFINITION
Classification: 156/535
(under subclass 349) Apparatus having means limited in their action to the bonding area of the lamina, and physically modifying the bonding surface by (1) changing the shape or
roughing of the joining surface to facilitate the bond, (2) removing foreign matter from the surface to aid the bonding action.
