ABSTRACT:
A book binding process and apparatus are shown wherein polyurethane adhesive (PUR) attaches a crepe portion of a book binding to a book block and hot glue attaches the crepe portion to the book cover. The PUR delivery system includes an inclined trough positioned adjacent a polyurethane adhesive delivery roll. A polyurethane adhesive source delivers polyurethane adhesive upon the inclined surface of the trough and the polyurethane adhesive is metered onto the roller as a function of the separation of the leading edge of the trough and the roller.
