Abstract
In a book binding apparatus, a book to be bound is clamped between a pair of plates, the distance between the clamps controlling the distance between a pair of groove bars engaging a cover to be bound to the book. A backup roll is positioned to engage the cover on the side opposite the groove bars, and to be movable along the cover to form grooves therein. A glue assembly is movable with the backup roll and includes a glue tube which is moved across the cover transversely of the direction of movement of the backup roll. The extent of transverse movement of the glue tube is controlled in response to the thickness of the book. A positive displacement pump supplies glue to the glue tube.
