7 Ply Corrugated Cardboard Production Line with 2500mm Width and 250m/min Speed for Industrial Packaging Manufacturing

This fully automated production line transforms paper reels into high-quality 7-ply corrugated cardboard sheets, designed for manufacturing durable packaging boxes with maximum efficiency and precision.

The RS-1500H hydraulic roll stand securely holds corrugated medium rolls in position, ensuring continuous paper feeding throughout the production process.

• Dual paper roll capacity enables non-stop paper changeover
• Full hydraulic control system with 6 hydraulic cylinders
• Cast iron curved arm construction for superior stability
• Advanced tension control with multipoint pneumatic brake system
• Internal mount paper roll clamp design prevents damage to corrugated medium

• Maximum paper width: 1800mm
• Maximum roll inner diameter: Ø1500mm
• Minimum roll inner diameter: Ø350mm

Hydraulically controlled carrier system transports corrugated medium rolls to the roll stand, reducing labor requirements and enabling rapid paper changes.

• Four-wheel sliding plate design operating on dual sliding rails
• Electric hydraulic control for forward/backward movement
