Comexi · Slitting & rewinding
S2 DS
A duplex slitter for straightforward flexible-converting requirements. Compare it with the turret S2 DT around reel-change frequency and handling needs, while checking the required reel finish and slit widths.

Understand the process
Turn a parent reel into production-ready reels
Slitting divides a wide web into narrower lanes and rewinds them onto finished cores. The goal is not only the right width: clean edges, suitable reel hardness and stable unwinding at the customer’s next process also matter.
Unwind and control
Feed the parent reel through guiding and tension-control elements. Different zones can require different tension levels.
Cut into lanes
Choose a supported razor or shear-cutting arrangement around material stiffness, thickness and edge-quality requirements.
Rewind and unload
Build finished reels with appropriate tension and contact pressure, then unload and identify them for the next operation.
What we review with you
- Reel quality
- Wrinkles, telescoping and uneven winding can involve tension, alignment and incoming reel condition; inspect the full process.
- Material selection
- Film, paper, foil and laminates do not necessarily use the same knife setup. Validate the actual structure.
- Real productivity
- Include loading, knife setup, reel changes, unloading and packing in the cycle assessment, not just maximum running speed.
