The single facer shapes the fluted medium and bonds it to a linerboard, forming a single-faced corrugated board. By applying precise heat and pressure, it ensures proper flute formation and consistent bonding. Its performance directly affects the quality of the corrugated board, including surface flatness, adhesive strength, and production stability. Modern single facers are equipped with advanced temperature and pressure control systems, along with quick-change flute roll mechanisms, supporting efficient and high-speed production of various flute types.
- This single facer incorporates a glue application system that eliminates the traditional glue pan, reducing glue splashing and preventing premature curing of the adhesive. By maintaining an optimal distance between the glue roll and the corrugating roll, it ensures consistent glue application and minimizes waste.
- Instead of a gear-based drive, it uses a servo motor with a custom variable-speed transmission. The main motor drives the unit directly via synchronous belt, improving energy efficiency by more than 30% compared to standard corrugators.
- During stops, the corrugating and pressure rolls disengage and rotate at a constant speed to maintain even temperatures across the surface. This design avoids defects such as the “banana effect” and ensures consistent board quality when restarting.
- The control panel is built directly into the single facer’s body, offering a clean layout and quicker operator response, all while saving floor space on the production line.
- Its patented front-push flute roll change system allows operators to complete a roll replacement safely and efficiently in under 10 minutes, enabling faster format adjustments without compromising safety.
- Unlike most positive-pressure designs, our single facer uses a negative pressure system that improves paper threading, keeps the workspace cooler, and prevents starch splatter or blockages inside the glue unit. It’s easier to maintain, with fewer moving parts and reduced downtime.
