Adding to an already versatile line of digital print finishing solutions, Duplo’s Integrated Folding System (IFS) achieves the next level in automation. Incorporating an in-line knife folder with a DC-series finishing unit, the IFS eliminates the need for a separate folding device and enables users to not only slit/cut/ crease with the DC-746/646, or slit/perforate/crease with the DC-446, but also fold digitally printed applications in a single pass using one system. By performing the functions of multiple machines, the system removes the bottleneck of the finishing process that occurs when setting up jobs separately. With a speed of up to 50 sheets per minute, the IFS can carry on the automation and capabilities of the integrated DC-series unit.
The Integrated Folding System has been designed to be easily set up using a centrally located control panel. Regardless of how complex the job requirements may be, the operator is guided throughout the complete programming process making it easy for inexperienced operators to set up and run the system with confidence. With the DC-746 IFS and DC-646 IFS, jobs are programmed via the PC Controller software.
The DC-746/646 IFS has a unique capability that no other system has which is to slit, cut, crease, and fold multiple-up pieces simultaneously in one pass. This means that when pieces are laid out in rows (see Fig. X), the cutter, creaser, and folder can perform their functions on more than one piece at a time.
Using two knife blades, the IFS can perform the most common folds including single, letter, Z, gate, and double parallel along with an infinite number of custom folds. The combination of the knife folding mechanism and the spring-loaded folding rollers make it possible to fold a wider range of paper stocks with greater accuracy and no adjustments. Even when switching between paper thicknesses, the spring-loaded folding rollers will automatically adjust to compensate for the thickness.
The DC-746 IFS can be configured with a long vertical stacker (15.75”) where the finished pieces, both folded and unfolded, are collected. The DC-646/446 IFS have the option to be configured with either the long stacker or a shorter vertical stacker (8”). The vertical stacking method accommodates twice as many pieces than shingle conveyors, enabling more pieces to be stacked before filling the receiving tray and requiring unloading. In addition, this method provides the ability to stack in rows, keeping the finished pieces neatly stacked. The vertical stacker can be added to the DC unit independently without the folder.
The Integrated Folding System is made up of several modules and can be configured to meet individual needs. For example, if space is limited, a customer with a DC-646/446 IFS can choose to add a short vertical stacker which is half the size of the larger, high capacity stacker.
Users who already have a DC unit can upgrade by adding a configuration kit and updating their software.
