(under subclass 209) Coating apparatus having means for handling individual sheets or for applying a coating to the faces of sheets arranged in a pile.
(1) Note. A "sheet" is defined in the definitions of subclass 231.
(2) Note. Where a stack of sheets is handled as a unit and coated as a unit rather than as discrete sheets, classification is in the appropriate subclasses which provide for the specific work handling or coating apparatus.
(3) Note. In this and the indented subclass may also be found, for example, devices for applying adhesive to the top sheet in a stack of sheets and then removing the coated sheet from the stack so that the next sheet may be coated. Here also are devices for stacking or unstacking sheets before or after the coating operation.

412, Bookbinding: Process and Apparatus,
9+, for apparatuses for applying glue or adhesives to the back of a stack of sheets combined with other operations provided for in that class; in particular, subclass 36 for adhesive tapes used in an edge binding operation; and subclass 37 for adhesives used in edge binding operations. Riffling or otherwise disturbing the stacked sheets to aid in the penetration of glue or adhesives between the sheets combined with adhesive or glue applying may also be found in class (412).
