After the last sheet feeds the sub grip unit [D] with the aligned stack (signature) firmly clamped
lowers away from the bottom of the stacking tray and passes the signature to the main grip unit
[E].
The main grip unit rotates the signature clockwise until it is vertical with its spine pointing down
and then lowers it to the spine alignment plate.
The grip unit drops the spine of the signature once onto the spine alignment plate to align the
edges of the sheets in the spine so they are even.
The main grip unit once again clamps the signature and raises to the gluing unit [F]
One cover sheet feeds from the inserter down through the vertical path [G] and stops on top the
cover transport unit [H]. Here the cover registration operation positions the cover to be joined
with the signature.
The gluing unit [F] applies glue to the signature spine.
The main grip unit lowers the signature and pushes it into the center of the cover below supported
by the cover fold plate.
Once the cover and signature are joined at the spine, the grip unit releases the signature, rises
to a higher position, and then clamps the signature again. The cover fold plate retracts and the
grip unit pushes the signature and cover down through the gap created by the retracted cover
fold plate. As the grip unit pushes the signature and cover through the gap, the sides of the cover
fold up around the front and back side of the signature.
The grip unit lowers the joined signature and cover (the book) to the book rotation unit [I] where
the book is firmly clamped between two opposing plates, released and then clamped again to
the book is positioned for the first cut.
In the trimming unit [J] the cutting blade (moving right to left) trims the bottom edge and retracts.
The book is rotated 180°, the blade cuts the top edge, the book is rotated 90° and the blade
cuts the fore edge.
The trimmer unit expels the trimmings from the cutting mechanism and they fall into the trimmings
collection box [K].
Finally, the finished book is lowered to the book stacking tray [L].
