Duplo DF-777 Automatic Desktop Friction Feed Paper Folder


The Duplo DF-777 folding machine has five popular sheet sizes (letter, legal, ledger, 1/2 letter, and 1/2 legal) pre-programmed for quick set up and user convenience. The automatic Duplo DF-777 paper folder precisely folds documents such as brochures, menus, letters and invoices at up to 135 letter-size sheets per minute. Users can select from six of the pre-programmed folds for touch-and-go folding or customize their own for non-standard folds. Fold position adjustments are easily done via the control panel. Once the paper size and fold type are entered, the ejection roller automatically moves into position. Cross folding for right-angle folds is also possible.


Non-stop productivity is also ensured with a 4-digit LCD counter and 500-sheet feed tray capacity. Ideal for any office, church or school, the Duplo DF-777 folder brings easy and reliable folding to your fingertips. With a patented friction feed system and adjustable paper and feed separator pressure controls, a wider range of paper stock up to 145 gsm can be fed with increased accuracy and consistency.
