The edge press plate motor (M36) turns on and retracts the edge press plate which releases the book
edge . Book rotation motors 1 and 2 (M42, M41) both switch on and turn the book rotation plates [4]
and the book counter-clockwise 90 degrees (front to rear).
The slide motor (M44) turns on and raises or lowers the book rotation grip unit [1] and the book [2] until
the bottom edge of the book is at the cutting position.
The edge press plate motor (M36) turns on and pushes the edge press plate [1] against the book [2] to
compress the edge of the book.
The cutter motor (M35) turns on and pushes the blade [3] against the edge of the book to perform the third
cut on the fore edge.
If more than 35 mm needs to be trimmed from the fore edge, the edge is trimmed twice in order to reduce
the size of the trimmings for collection and disposal.
