Abstract: A glue actuator mounting assembly adapted to mount to a folder apparatus has individual opposed guide strips forming a sheet path and glue actuators slidably mounted across the sheet path, such that individual actuators may be moved and repositioned laterally, and guide strips may be positioned to allow each glue actuator, regardless of lateral position, to have access to a sheet moving in the sheet path. In a preferred embodiment a stop bar is included having extendable tabs for extending between guide strips and forming a stop for sheets moving in the sheet path. In a preferred embodiment the actuators are mounted on slide rods that engage open slots in a carriage of the actuator mounting assembly such that the rods carrying the actuators, along with the actuators, may be lifted off the actuator mounting assembly.
