ABSTRACT:
Bookbinding apparatus for applying glue to the backbone edge of collated book sheets conveyed through a gluing station comprises counter rotating applicator rolls for transporting glue from a rectangular glue pot to the backbone the rolls substantially completely spanning the parallel sidewalls of the glue pot so that glue can not flow between the ends of the rolls and the side walls. Doctor blades extend from the ends of the glue pot to respective rolls so as to confine the adhesive below the rolls. One of the doctor blades is linearly retractable from its roll to an extent limited by a linearly adjustable stop which meters a volume of glue carried to the book in direct linear relation to the adjustment of the doctor blade stop.
