The Duplo DFC-120 is a used book binder — also known as a collator or gathering machine — designed to assemble multi-page document sets by drawing sheets from multiple feed positions and compiling them in sequence. Duplo is a well-established manufacturer of document finishing equipment, supplying print shops, copy centres, and commercial printing operations with collating, binding, folding, and trimming solutions.
At the heart of this machine is a friction collating system with 12 individual loading positions, each with a capacity of 28 mm at 64 g/m². The main output tray — referred to as the boom — offers a larger holding capacity of 78 mm at the same paper weight. The machine handles paper dimensions ranging from 160 × 140 mm up to 320 × 450 mm, covering formats from A5 through to A3SR, and accepts paper weights between 53 and 128 g/m². Output speed reaches up to 4,200 sets per hour, selectable across five speed settings depending on the chosen operating mode.
Four collation modes are available. Normal mode gathers sets sequentially from the top position downward. Interleaving mode allows a specified number of sets to be separated by an inserted sheet, such as an envelope. Duplicate mode pairs two adjacent positions so they work in tandem. Block mode divides the machine into upper and lower halves, stacking paper alternately from each block. The machine also features a three-step overlap control, automatic position selection, and programmable set counting.
The detection system is comprehensive, monitoring for unremoved paper, double-feed errors (detected optically), empty positions, paper jams, a full output tray, and errors from connected downstream devices. The feeding mechanism incorporates adjustable pressure on the feed wheels and back-pressure regulation on the separator, which the seller notes improves handling of problematic paper types.
This unit supports integration with finishing equipment — including sewing, folding, and trimming machines — connected to the stacker output. When a paper size is selected on the stacker, the setting is automatically communicated to all linked finishing devices. Two DFC-120 units can also be paired to create a 24-position assembly, with paper directed either right to the output hopper or left toward finishing machines. The listing notes that the electronic components have been renewed.
Physical dimensions are 820 × 560 × 1,144 mm and the machine weighs 74.2 kg. Power requirements are 230 V, 50 Hz at 2.8 A. A base stand is included with the unit.
