The Comexi DUO2 slitter is a top range machine, which will provide you with excellent results in both quality and productivity, even in the most demanding jobs

Due to its robustness and design, it will generate large diameter reels at the exit at a very high working speed.  

Thanks to its regulating and control elements it will produce jobs with handling difficulties, without any problem. With the Comexi DUO2 you will not have any problems working with thicker structures in the flexible packagings sector or even with aluminium, wax or non-woven packagings.

Main benefits for you

Success with the most difficult jobs
Success with the most difficult jobs

The Comexi DUO2 is an all-purpose machine capable of performing demanding jobs successfully and at speed, and this means that large reels can be supplied to those flexible packaging markets who ask for them. Thanks to its top range control systems, it will efficiently manage webs that are difficult to control because of their great thickness, their gauge difference or their low adherence. Thanks to its leading speed, its acceleration, its high degree of automation and control, it will beat productivity records.

Maximum quality and productivity

With the NIP tension gap system, you will work with different tensions in rewinding and unwinding. It includes the ALTS rewinding system with a motorized horizontal lay-on pressure roll, which will give you greater stability in rewinding. The Comexi DUO2 provides a real reading of the tension since it has independent motors for each shaft. Searching for quality does not mean compromising productivity, and you will have a high production rate thanks to the spectacular acceleration ramps that will help you work at a higher average speed. This will be particularly important when producing large format reels.

Easy use and maximum personalisation

The Comexi DUO2 looks after whoever works with it. With ergonomic handling, it is very intuitive thanks to tools like the PC touch panels where you can mark the machine rhythm and also manage and store the production data. The machine includes , very useful tools like the automatic recommendation of the rewinding taper.

We adapt to the needs of each client and therefore we offer the possibility of personalising the machine with multiple automating options: splicing tables, automated slitting, automatic reel unloading, robotised labelling of finished reels, robotised transport and palleting, multiplying the product offer if a laser perforation system is installed.
