- Completes the reinforcement patch application and handle-hole punching processes in a single pass during paper bag production, without requiring an external patching or punching station.
- Operates in full synchronization with the reliable main frame and feeding mechanisms of conventional square-bottom SOS paper bag machines.
- Automatically cuts reinforcement paper supplied in rolls or special reinforcing film to predetermined fixed sizes for patching.
- Features a uniform coating system that uses water-based adhesive (water glue) to bond the cut patch smoothly to the paper surface.
- Immediately after bonding, an integrated shaped die-cutting station creates precise, smooth hand holes aligned with the mouth of the bag.
- Its design conceals the patch on the inside, giving finished packaging products a clean, elegant appearance with no visible patch marks on the exterior.
- By creating a double layer around the hand hole, it maximizes the bag's resistance to tearing and deformation under heavy loads.
- For printed roll applications, it features an advanced servo registration control system that ensures the patch and hand hole are positioned precisely at the center of the graphic designs.
- Minimizes the need for manual labor throughout the production line, delivering significant savings in labor and time for businesses.
- Features a user-friendly mechanical design that quickly adapts to orders for bags of different sizes and optimizes make-ready times.
