Circulating Feeder overview

The Circulating Feeder Vacuum Suction Paper Folder is a precision-engineered industrial-grade circulating feeding buckle folding system designed for medium-to-high volume post-press finishing, built to meet stringent quality standards for binderies, packaging facilities and publishing houses.

It is equipped with a circulating feeding system that delivers smooth, accurate circulating vacuum suction feeding via air-suction circulating feeding technology, ensuring consistent sheet transport for stable production runs. Integrated double sheet detection function prevents feeding errors and protects the folding unit from damage, while the PLC controlled system enables precise fold setting, easy operation and quick format changeovers.

Equipped with precision buckle plates, it supports a comprehensive range of fold patterns including half fold, tri fold, accordion fold, double parallel fold, cross fold, gate fold and letter fold, making it highly versatile for instruction leaflets, carton instruction inserts, pharmaceutical inserts, promotional brochures and product catalogs. Suitable for paper stocks from 40 to 210gsm at operating speeds of up to 180m/min, it delivers precise fold registration and clean, crisp creases for professional-grade output quality.

Built with a heavy-duty industrial frame and wear-resistant folding components, it requires minimal routine maintenance and ensures stable long-term performance. CE certified for safety and quality compliance, this circulating feeder folder is a reliable and cost-effective solution for businesses seeking to enhance post-press folding precision and production efficiency.

Folded product applications

Brochures and catalogues

Brochures and catalogues

Parallel, roll and gate folds in 100–200 gsm stock, folded square enough to stack flat.

Production considerations

Commercial print shops alternate between brochure, catalogue and mailer formats. Fold-pattern coverage and changeover time therefore matter alongside running speed.

T490, T600 and T780 configurations cover different sheet formats. Round-pile feeding can support longer runs on compatible T600 and T780 lines. Match the plate set and feeder to the real job mix.

Book signatures

Book signatures

Parallel and cross folds for section-sewn and perfect-bound work.

Production considerations

Publishing signatures require stable register through parallel and cross folds so sections collate and bind cleanly.

T600 and T780 configurations address different sheet formats. A compatible round-pile feeder can reduce stops on long batches. Set the fold pattern and feeder against the actual signature stock.
