T520/14-buckle overview

The T520 14-Buckle Leaflet Folding Machine is a professional-grade automatic buckle folder purpose-built for commercial post-press finishing, optimized specifically for leaflets, flyers, brochures and promotional inserts.

Featuring a 14-buckle plate configuration, it supports an extensive range of fold patterns including parallel fold, cross fold, accordion fold, gate fold and letter fold, enabling intricate multi-panel layouts that meet diverse promotional print design requirements. It processes 35–200gsm paper stocks from 60×100mm up to 520×1000mm at a top speed of 180m/min, delivering precise fold registration and sharp, uniform creases for consistent, professional output.

Equipped with a high-performance suction feeder, double-sheet detection and an optimized anti-jam paper path, it ensures stable uninterrupted feeding with a 550mm maximum paper pile height, minimizing manual intervention and production downtime. PLC-controlled with stepless speed adjustment, it allows flexible setup for different job specifications and supports optional configurations including independent knife units, vertical stackers and CCD vision inspection systems.

CE-certified and durably constructed for continuous operation, the T520 14-buckle folder is a reliable workhorse for print houses, commercial printing facilities and promotional product manufacturers.

Performance Features

  • Modular folding units: 4~20 buckle plates optional for the first folding station, 4~10 buckle plates optional for the second station, compatible with a wide range of folding patterns.
  • Stable sheet feeding: High-performance feeder with 3-hole suction wheels delivers precise sheet positioning and adapts to various paper grammages.
  • High-wear folding rollers: Helical-groove steel-base polyurethane rollers with 75% larger paper contact area, featuring anti-slip, wear-resistant and rust-proof performance.
  • Automatic pile control: Dual automatic adjustment of pile height enables uninterrupted feeding and reduces manual intervention.
  • Electrical control: PLC with variable frequency stepless speed control, standard overload protection, and flexible operating speed adjustment.
  • Detection and protection: High-sensitivity double sheet and paper jam automatic stop system ensures stable operation; CCD Vision Inspection System is available as an option.
  • Process options: Supports scoring, perforating and slitting functions, covering diverse post-press processing scenarios with one machine.
  • Belt drive: Belt drive structure guarantees low noise and low vibration; precision-engineered sheet feeding angle effectively prevents paper wrinkling.

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.

Packaging inserts

Packaging inserts

Leaflets and promotional inserts folded to carton size, packed by automatic equipment.

Production considerations

Carton inserts and promotional leaflets are folded to a finished size that downstream equipment can pick up consistently. Square edges and flat stacks may be needed for automatic packing.

Select the folding platform around the carton insert and printed stock. Review any knife or pressing step separately and confirm module envelopes and interfaces for the ordered line.
