Duplo DF-1300L Paper Folding Machine

Duplo DF-1300L Folding Machine

Duplo has been the leading manufacturer of automated paper folders since introducing the world’s first auto setting, friction feed folder over 40 years ago. The DF-1300L, our air suction feed model, brings it with expanded capabilities to handle digitally printed output and longer sheet sizes. Our folders are widely known for their ease of use and reliability to process everyday documents such as letters, invoices, and flyers. The DF-1300L delivers with more diverse applications such as tri-fold brochures, letter landscape guides, and much more.

Quickly fold office documents printed off your larger format press with the compact DF-1300L by its side. The DF-1300L features high speed folding up to 310 sheets per minute and can process
sheets up to 25.5” in length. The air suction feed system makes it possible to feed coated sheets as well as bond, NCR, and offset. The folder utilizes optical and ultrasonic sensors to detect any
double feeds as well as side air to aid when feeding longer sheets. It fits perfectly in corporate, school, church, and medical office environments as well as small digital print shops.

Get easily started with the touch of a few buttons using the color touchscreen panel. The DF-1300L comes pre-programmed with six of the most popular fold styles to save you time. Standard paper sizes such as letter, legal, ledger, half letter, and half legal are automatically detected when loaded on the feed tray. The delivery stack roller adjusts according to paper size and fold type without intervention.

Custom fold styles with non-standard paper sizes, including larger formats, are created by digitally moving the fold plates on the control panel and can be saved in one of the 30 job memories for future use. The DF-1300L can also perform cross folds by reprocessing single folded sheets and folding them in a second direction.
