Abstract
A system for positioning a cover relative to a book block. The system comprises a drive unit to cause movement of at least one of the book block and the cover and a position sensor operable to detect at least one of a position of the book block and the cover. The position sensor is operable to generate a position signal indicative of the position. The system also comprises a controller in communication with the position sensor and the drive unit. The controller is operable to receive the position signal and to control the drive unit based on the position signal to adjust a relative position of the cover and the book block.
