High speed automatic laminator equipped with top sheet and bottom sheet automatic feeding system, is suitable for the automatic laminating for preprint sheet to corrugated paperboard. Several patent technologies are adopted in High speed automatic laminator, and it is a newly developed high efficiency automatic laminator. Top sheet sucker feeder system and bottom sheet suction belts feeding system make sheets feeding more smooth and reliable; skillful front register’s design ensures that bottom sheet will never exceed the top sheet and make the die cutting easier; pre –stacking table can be used for preparation of next batch of top sheet while the laminator is running, increases the machine’s productivity; Siemens PLC control system and other imported electric equipment simplifies the electric structure and stabilizes the control system.
