The DF-850 Tabletop Paper Folder is one of Duplo’s quietest tabletop folding machines. It features a speed of up to 241 sheets per minute and can process 11" x 17" sheets. The DF-850 utilizes a three-roller friction feed system to process a wide range of paper stocks and can also perform cross folds by reprocessing single folded sheets and folding them in a second direction.
