Abstract
Apparatus for trimming a perfect bound book is disclosed having a platen for supporting a portion of the book as it is trimmed. A clamp holds the book against the platen, and a blade is provided having a cutting edge with the blade being movable toward and away from the book platen between a retracted position and an operable position in which the cutting edge is in operative engagement with the book. An ultrasonic (or other vibratory) member carries the blade, and the ultrasonic member is rendered resonant so that the cutting edge trims the book along the side of the book. A method of trimming a book using a vibratory blade is also disclosed.
