Automatic Folder Gluer
Packaging manufacturers can use the Automatic Folder Gluer to turn die-cut paperboard and corrugated board into finished boxes with faster folding, more accurate gluing, and more consistent forming quality. By automating sheet feeding, glue application, folding, pressing, and delivery, the Automatic Folder Gluer reduces manual handling and supports stable high-volume carton production.
During operation, die-cut box blanks are fed one by one through the conveyor belt and transferred to the gluing section. Glue is applied to the required positions, then the folding mechanism forms the box structure before the pressing section bonds and stabilizes the finished carton. The completed boxes are then delivered through the output conveyor for collection or the next production stage.
The automatic folder gluer is suitable for packaging producers that need efficient box forming, clean adhesive application, stable folding accuracy, and reliable output for paperboard boxes, corrugated cartons, and other folded packaging products.

-
Feeding SectionThe feeding section uses independent motor synchronous drive and a multi-belt feeding structure to keep sheet feeding stable at high speed. With flexible width and length adjustment and continuous high-pile feeding, the Automatic Folder Gluer ensures smooth and accurate sheet delivery with less manual intervention.
-
Alignment SectionThe alignment section uses automatic correction and adjustable pressing structures to handle paperboard of different thicknesses. This improves sheet conveying accuracy and keeps finished boxes more consistent during continuous production.
-
Pre-Folding SectionThe pre-folding section uses a special-angle pre-folding design to fully shape key crease lines before final folding. An optional multi-hook system can be added to improve box opening performance and support more complex carton structures.
-
Crash-Lock Bottom SectionThe crash-lock bottom section combines multi-hook bottom forming with an adjustable glue tank structure. It supports quick adjustment for different box types and paperboard thicknesses, creating firm bottom bonding and faster job changeovers.
-
Final Folding SectionThe final folding section uses 180° double-fold forming and independently controlled left and right folding belts. This corrects the box blank direction, improves folding accuracy, and keeps sheet conveying straight and stable.
-
Pressing SectionThe pressing section integrates photoelectric automatic counting, water-spray alignment, and paper jam detection. With quick belt adjustment, it ensures finished boxes are neatly pressed, accurately counted, and reliably delivered.
-
Box Collection Conveyor SectionThe box collection conveyor section uses an online-adjustable moving stacker pressure belt and balanced air-pressure control. Synchronized with the main machine, it keeps finished boxes stacked steadily and pressed evenly, improving continuous production efficiency.
The Automatic Folder Gluer can process various corrugated boxes, color cartons, and color packaging boxes, including the following box styles:
- One-End Glued Box
- Lock Bottom Box
- Full Flap Auto Bottom Box
- 4-Corner Glued Box
- Specialty Cartons
- Display Box
- 6-Corner Glued Box
- Reinforced Lock Bottom Box
- Divider Box
- Lock Bottom Box with Divider
※ For production of custom-shaped boxes, dedicated accessories are required.
