Abstract
A glue application system (10) for applying glue to books (12) moving from a binder (16) along a predetermined path (14) includes a first roller (30) which rotates in the predetermined path to apply glue to the books. A heater (114) maintains the temperature of the first roller at a predetermined temperature. A second roller (32) rotates in the predetermined path, downstream of the first roller, to apply glue to the books. A second heater (130) maintains the temperature of the second roller at a temperature less than the temperature of the first roller. A glue reservoir (50) disposed below the first and second rollers contains a supply of liquid melted glue (56). A pump (70) pumps liquid melted glue up to the first and second rollers. An electric motor drive assembly (89) is selectively engageable to drive the pump when a binder drive assembly (79) is not driving the pump.
