Duplo DF-850 Folder Machine


The Duplo DF-850 folder machine is a manual-setting paper folding machine which folds documents at up to 241 single letter size half-fold sheets per minute while still being user-friendly. Whether the application is a letter, flyer, brochure, invoice or billing statement, set up is simple. There are two easy-to-follow charts that indicate where to position each fold stopper for six popular folds. For non-standard paper sizes and custom folds, adjustments knobs enable the user to make minor adjustments to achieve the desired fold.


With a patented friction feed system and adjustable paper and feed separator pressure controls, a wider range of paper stock can be fed with increased accuracy and consistency.  A 4-digit LCD counter and a 500-sheet feed tray capacity ensure non-stop folding. The Duplo DF-850 is ideal for any office environment, school, or church. Additionally, the Duplo DF-850 paper folder is capable of cross folding with right angles with no additional parts or adjustments required.
