Product Overview
The Double Facer Machine is an important section of a corrugated board production line, used for bonding the single-faced corrugated board with the liner paper to produce double-faced corrugated board.
The machine combines heating, pressing and conveying functions to complete the continuous bonding process. It is installed after the Glue Machine and before the Slitter Scorer and NC Sheet Cutter in a corrugated board production line.
The Double Facer Machine is available in different working widths and configurations to match various corrugator line speeds and production requirements.
Key Features
- The heating plate size is 160mm x 600mm (height*width). The surface of the heating plate has been grounded. The number of heating plates can be selected from 8 to 20 pieces according to the corrugated production line speed.
- The hot plate adopts a dense gravity roller structure.
- The lifting and lowering of the pressing roller adopts an electric structure.
- The left and right correction adjustment of the upper conveyor belt adopts automatic two-side adjustment. There is 1 set of upper conveyor belt tensioning system, 1 set is manual (fine adjustment), and 1 set is pneumatic adjustment (fast).
- The heat conduction piping of the heating plate is divided into 6 sections to control the temperature.
- The upper acupuncture belt adopts a double-cylinder S-type acupuncture belt tensioning device.
- The lower belt adopts S-shaped manual deviation correction and tensioning mechanism, the structure is simple and practical, and the lower belt has a set of manual fine-tuning type.
- The surface of the driving roller is covered with wear-resistant rubber and has a medium height to ensure the smooth output of the cardboard.
- The electrical components adopt international famous brands, the device works stably and the operation is reliable.
- The main drive motor is a variable frequency speed regulating motor, with large torque at low speed, wide speed regulation range, reliable use and simple maintenance.
- The interior of the hot plate is a partition isolation structure, so that the steam flows in an S-shaped direction, and the separation function of steam and water is obvious, which improves the utilization rate of steam.
- The main frame of the double facer is made of high-strength national standard profiles, with firm structure and beautiful appearance, suitable for high-speed work.、

Working Process
The working process of the Double Facer Machine includes:
1. Board Alignment and Feeding
Single-face corrugated board and liner paper are accurately aligned and continuously fed into the double facer section.
2. Gluing and Hot Pressing
Starch adhesive is applied to the flute tips of the single-face corrugated board. The layers pass through the heating plates and pressure section, where heat and pressure activate the adhesive and bond multiple layers together.
3. Heating and Drying
The steam-heated plates provide controlled heating to remove moisture from the adhesive and ensure stable bonding quality. Pressure can be adjusted according to different board structures and thicknesses.
4. Cooling and Forming
The bonded corrugated board passes through the cooling section, where heat and moisture are gradually removed to improve flatness, stiffness, and dimensional stability.
5. Finished Board Transfer
The finished corrugated board is continuously delivered to the next process, such as thin blade slitting, scoring, and sheet cutting.
