• The hot-plated is composed of intensive gravity press roll structure, while its' inner structure is separated into "S" shape, which are good for steam and water separation, and improves the steam utilization. 
• The lifting of press roll is controlled by hydraulic.
• The upper conveyer belt is designed to adjust offset automatically, and two sets of tension adjustment system are additional, one for manual fine-turning, one for quick pneumatic adjustment.
• The upper "S" shape cotton belt device is equipped with double cylinder.  
• The lower cotton belt is available for "S" shape manually adjusting offset and tension, one set of pneumatic fine-turning system is additional.
• The drive roll is covered by wearproof rubber, ensures the cardboard flat transmission.
• The main drive motor is an energy saving converter motor, with the features of  low speed and large torque, wide rang of speed adjustment, and easy maintenance.
• All of the electrical components are in according with the national standard.
• The main structure is made of high tensile steel and GB profiles, with a firm structure, beautiful shape, running stable with high speed. 

NC thin blade slitter scorer

• Blade and scorer configuration: 4 blades with 6 scorers and 5 blades with 8 scorers are available.
• The blades and scorers are available to rise and drop controlled by electrical, which is designed to adapt for the different thickness of cardboard.
• The machine frame is moveable transverse also controlled by electrical, which is make for the offset adjusting.
• New style of high speed thin edge cutting system, ensure a glossy and smooth incision
• Equipped with pneumatic controlled self blade sharpening syetem, so as to sharpen the blades without stopping the machine, the sharpening frequency is available to be set up depends on different cardboard.
• The blades are made of tungsten alloy steel, the lifetime will over 3 million Meters.

NC Helical cross cutter

• 200 group of orders storage is available, changing order automatically without stopping the line, also could be implanted into production management system.
• The transmission gear of cutter shaft is made of precise forging steel with high frequencny quenching, which makes an non-backlash and high precision transmission.
• The blade is made of rapid steel, to reach a long lifetime, and the blade is helical structure designed, with sawtooth shape, scissors cut.
• The sun shape wheel type of paper feeding roller guarantee a uniform pressure and stable delivery.
• The main structure and frame are made of gray cast iron, it's good at anti-vibration and rigidity.
