Corrugated Glue Machine

Uniform Gluing for Strong, Consistent Corrugated Board Bonding.

Corrugated Glue Machine Overview

The corrugated glue machine is also known as a glue applicator. It is an essential part of a corrugated board production line. This machine is installed between the corrugator bridge and the double backer.

AGICO PAPER’s corrugated glue machine applies adhesive evenly and accurately to the flute tips of single-face corrugated board. The glued board then enters the double facer. There, it is pressed and bonded with the liner to form strong, multi-layer corrugated board.

Working principle of the Glue Unit

The glue unit works through four steps: glue feeding, glue metering, flute-tip gluing, and bonding. The machine controls glue delivery, application, and glue volume. The glue is applied evenly to the flute tips of single-face corrugated board.

Board feeding

The single-face corrugated board is fed in from the single facer and enters the glue unit. It first passes through the preheating roll. This adjusts the board’s moisture and temperature. It also helps the glue adhere evenly in the next step.

Glue Application

The hard chrome-plated anilox glue roll rotates through the glue pan and picks up glue. It spreads the glue across the roll surface. The roll gap controls the glue film thickness. You can adjust the gap by electric control with a digital display or by hand.

Flute-Tip Gluing

The glue roller contacts the single-face corrugated board and applies glue to the flute tips. The glue does not directly contact the flute valleys. A pneumatic lifting system works with a hold-down bar or pressure roller during gluing.

Board Merging and Bonding

The glued single-face corrugated board meets the liner. Both then enter the double facer and pass through its heating and pressing section. With heat and pressure, the glue cures and the paper layers bond together. This forms the finished corrugated board.

The glue roll runs in sync with the line speed. When the machine stops, it can run independently at a low speed.

Why Choose Us

Stable Gluing Quality

AGICO PAPER’s corrugated glue machine provides stable gluing performance. It helps reduce problems such as delamination, glue penetration, and board wrinkling. This also helps reduce defective boards and rework, lowering production waste.

Lower Glue Consumption

Accurate glue application helps reduce excess glue and glue waste. When starch-based glue is used for corrugated board production, you can reduce glue consumption and long-term production costs.

Different Flute Types

AGICO PAPER’s corrugated glue machine is suitable for different flute types, such as B, C, and E flute. The gluing settings are easy to adjust when changing orders. This helps shorten equipment adjustment and production preparation time.

Stable High-Speed Operation

The gluing unit runs stably and can work with medium- and high-speed corrugated board production lines for continuous production. A stable glue supply helps maintain consistent gluing performance. It also reduces production interruptions caused by glue supply or gluing problems.

FAQ

1. Where is the corrugated glue machine installed?

It is installed between the corrugator bridge and the double facer. It applies glue to the single-face corrugated board before entering the double facer.

2. Which flute types can it support?

We support common flute types such as B, C, and E flutes. The gluing parameters can be adjusted according to production needs.

3. Can it be added to an existing corrugated board production line?

Yes. It supports production line upgrades. We can provide an upgrade solution based on the working width, installation space, and production speed.

4. What daily maintenance is required?

Clean the glue tank and glue roll regularly to prevent starch-based glue from drying. Check the transmission parts to maintain stable operation.

5. Will the glue dry on the glue roll during stops?

No. The glue roll keeps running at low speed during stops to prevent glue from drying.
