Corrugated Board Manufacturing

• Paper feeding is carried out by using vacuum absorption method, a high-pressure blower is equipped to ensure the stable corrugation process at high speed;
• The width of groove on lower corrugating roll is less than 2mm, efficiently preventing the marks of stripes on corrugated cardboard;
• Universal joint transmission system is adopted to reduce vibration, enabling the operation more stable and reliable;
• Reduction gearbox is designed with oil-immersed lubrication to lower the machine vibration;
• Automatic glue feeding, pneumatic control of glue application and return can provide cushion effect;
• Engraved glue applicator roll is chrome plated;
• The glue width is electrically adjusted with convenience and fastness;
• The surface of glue applicator roll is engraved and chromium-plated;
