Glue actuator mounting for a form-folding and gluing machine

A sheet stop and actuator assembly for a sheet folding apparatus, comprising:

• a frame including cross members adapted for mounting to the sheet folding apparatus;
• a plurality of opposed, substantially flat, guide strips slidably mounted to the cross members, the guide strips spaced apart and forming a sheet path with a width greater than the width of any sheet to be processed, wherein sheets may enter from and exit to the sheet folder apparatus, and wherein any individual guide strip may be added or deleted, and may be positioned at any position across the width of the sheet path;
• an adjustable actuator carriage mounted to the frame above the sheet path, position of the actuator carriage freely adjustable in the direction of sheet movement in the sheet path, and adapted to engage at least two parallel rods extending across the width of the sheet path;
• two or more glue actuators slidably mounted on two parallel rods engaging the carriage and extending across the width of the sheet path, such that the two or more glue actuators may be moved laterally along the parallel rods to any position across the width of the sheet path;
• and
• a stop bar mounted to the actuator carriage and having mount locations outside the width of the sheet path, the stop bar extending laterally across the width of the sheet path, the bar having extendible and retractable tabs adapted to extend between the guide strips across the sheet path, forming thereby a stop for sheets moving in the sheet path;
• wherein combined position adjustability of the carriage and guide strips allows glue actuators to be positioned to place glue dots at any position across the width of a sheet while maintaining a sufficiency of guide strips positioned to form the sheet path.
