Main benefits for you

Automatic slitting system
Automatic slitting system

Positioning of knives and counter knives is completely automatic; therefore, circular knives and razor blades are positioned rapidly and accurately

High quality, greater productivity
High quality, greater productivity

It offers the highest quality and uses a NIP to isolate the tension between unwinding and rewinding, a horizontal lay-on-roller ALTS rewinding system for extra stability, independent motors on each shaft and true tension readings. S1-DS has amazing acceleration rates that increase the average speed, especially when producing largeformat reels.

Easy to use
Easy to use

The S1-DS slitter is ergonomic and easily operated, thanks to tools like the PC Touch- Panels that set the machine’s pace and store production data. The machine incorporates useful tools, such as the automatic rewind taper. Comexi offers the option of customizing the machine with several automation options: splicing tables, slitting automation, automated reel unloading, robotic labelling of the finished reel, robotic transport and palletizing and laser perforation system.
