Performance
- The JLMT-1450W automatic flute laminator supports three-in-one lamination as well as single-layer corrugated board-to-paperboard lamination.
- The laminator consists of a top-sheet feeding unit, paper transfer unit, top-sheet registration unit, upper and lower corrugated-sheet feeding and registration units, harmonic-drive registration system, dual gluing systems, and a pressing conveyor.
- The feeding unit transfers the top sheet smoothly to the delivery rollers. Feeding is driven primarily by belts, while upper pressure wheels maintain stable sheet contact during transfer.
- A side-lay registration system positions the top sheet accurately before lamination.
- The upper and lower corrugated sheets are fed by suction belts, ensuring smooth transfer to their respective registration units.
- In each corrugated-sheet registration unit, pushers move the sheets forward while maintaining feeding accuracy.
- The dual gluing systems apply adhesive to the corrugated sheets to support secure bonding between the laminated layers.
- After gluing, the pressing conveyor applies consistent pressure to the combined sheets to complete the lamination process.
Main Lamination Process
- The upper and lower corrugated sheets advance synchronously through the flute laminator. One side of each sheet is positioned by a side lay, while spring lays on the opposite side guide the sheet back against the side lay for accurate lateral registration. The pushers then control the forward movement through the laminating process.
- Adhesive is first applied to the lower corrugated sheet, which is then pressed together with the upper corrugated sheet to form a multi-layer corrugated base. The combined board passes through the next gluing unit, where it is laminated to the paperboard top sheet. The final pressing completes the finished multi-layer laminated board.
- The automatic flute laminator is equipped with a harmonic-drive system that controls registration between the paperboard and corrugated sheets. In addition to multi-layer lamination, the laminator can process single-layer corrugated board with paperboard and supports lamination in various configurations, including 1+2, 3+2, 1+2+2, and 3+2+2.
