Folder-Gluer Folding & Creasing: Precise Folds, Solid Glue

A folder-gluer's core job is folding, gluing, and forming die-cut board. Creasing depth and folding precision directly decide whether boxes form square and open smoothly.

The Scenario: Three Difficulties in Folding and Forming

Folder-gluer folding is hard in three ways:

Pain Points

• Creasing too deep or shallow—folds crack or don't fold fully;
• Poor fold alignment—boxes form crooked, not square;
• Irregular-shaped boxes have complex fold paths, harder to form.

The Solution: Three Process Control Points

Folder-gluer folding has three points:

1. Creasing depth control. Adjust creasing depth by board thickness so folds are clean without cracking.

2. Folding precision adjustment. Precisely set folding guides and blades for accurate alignment.

3. Irregular-box adaptation. Adjust folding stations for irregular boxes to achieve complex forming.

The Result: Precise Folds, Solid Glue

With creasing and folding controlled, boxes form square and glue holds—yield rises.
