Solutions for folding a square box
As customer expectations rise nationwide, box makers are pushing for higher quality finished cartons that meet evolving packaging demands. Sauer System delivers the precision tooling, machine upgrades, and technical services converters need to achieve one ultimate goal — folding a square box consistently.Precision Scoring for Perfect Folds
At the core of quality folding lies proper scoring. Sauer System’s proprietary G3 male scorers set the industry standard for accuracy, producing deep, consistent score lines while preventing liner cracking. Available in custom configurations, they bring unmatched precision to any application. Complementing them are bonded polyurethane female scorers, engineered for even pressure across shafts with an exact ground finish — ensuring every fold begins with a flawless score.Precision Heads and Alignment Stability
A square box starts with straight, skew-free sheet feeding. Sauer System’s precision-manufactured heads maintain tight outer diameter tolerances for flawless board transfer. Paired with yoke upgrades, they help keep heads aligned, reducing gap variation and improving overall folding consistency.
Controlled Folding for Consistent Results
The folding section is where twisting and skewing can compromise gap variation consistency. Sauer System provides innovative sheet control solutions that tackle these issues head-on. The Roller Eliminator Upgrade replaces rollers with a continuous spring-loaded pressure shoe that keeps steady nip pressure on the folding belts. The FRX Adjustable Folding Rod Upgrade delivers smooth, clean flap folding and repeatable setups — ensuring optimal fold quality.Beyond Scoring and Folding
Sauer System’s expertise extends across the entire machine. Specialized solutions include precreaser heads and rings with proprietary profiles for improved crease consistency, split folding belt pulleys designed for easy maintenance, and comprehensive field service programs for troubleshooting gap variation and optimizing performance.
