Er exceed. When laminating, it is very easy to make top paper and bottom paper alignment, or top sheet exceeded. 6. Fully automatic glue supply system: glue will be automatically supplied during lamination, and recovered, avoiding glue wasted. 7. Scientific design for linear speed of metering roller, avoiding glue thrown when high-speed running. 8. The whole machine adopts plc control system, compared with other time-delay device or middle relay control, the bottom paper is transferred more precise and stable, furthermore, speed is greatly increased, and circiut breakdown can automatically display and alarm. 9. Clean the lower roller in gluing section by blade with circulated water, complete cleaning, convenient to replace the blade 10. Floating movable pressing section is adopted to make the laminated paperboard smooth. This section can be moved front and back to take in paper conveniently. 11..
