KB 2160 SHEETER

Material to be cut:
- Fine papers starting at 25gsm
- Carbonless paper: 40-250gsm Operating speed: 300m/min
Operating speed: 300m/min

The Koehler Paper Group is one of Europe’s most prestigious groups. It specialises in the production of thermal paper, carbonless paper and special fine paper.

Two years ago, it entrusted PASABAN with the task of designing and building a sheeter for its plant capable of meeting very high quality, production and flexibility objectives. The company that manufactures “Papers for the future” also wanted to prepare for the future and to provide its clients with a finished product in perfect condition whilst achieving the necessary productivity to finance a high service and the quality of its stacks.

With the Pasaban KB 2160 sheeter, the Koehler Group has solved a frequent problem affecting fine and carbonless papers. They are special papers having substantially less weight and rigidity than other papers, so the surface of the sheets ends up scratched as a result of the high-speed cutting and handling thereof. Pasaban sheeters are capable of processing paper of up to 30gsm at 300m/min without scratching it or hindering the processing thereof.

Pasaban’s technology and know-how guarantee that the sheeter will work properly and fulfil all the goals of the client to its complete satisfaction. On 28 April 2015, the Koehler Group inaugurated the finishing plant with the PASABAN sheeter.

The characteristics of this sheeter are aimed mainly at obtaining:

• Perfectly cut sheets.
• Sheets without scratches or microcapsule burst.
• A good stacking quality for all kinds of paper.
• A high output, thanks to having six unwind stands and an operating speed of 300m/min.
• The flexibility to deal with frequent order changes in regard to both the format and the quality.
• This flexibility must be coupled with reliability.
• Good ergonomics in the operation of the machine.

Sheeter tech specs:

• Reel width: 2,250mm
• Net width: 2,160mm
• Unwind stands: 6
• Cutting tolerance: ±0.5mm
• Cutting block: 300m/min
• Automatic reject gate synchronised with the detector.
• Overlapping system for light paper.
• Automatic stack changeover without sheet loss.
• Fully automated format and order changeover.
• Dust removal equipment.
• Special ergonomics kit for operators for making it easier to operate and safely access the machine.

Special specifications for increasing productivity and flexibility:

• The sheeter can load six (6) reels in an automated manner and automatically unload the cores of the finished reels. Changing from one set to another takes less than three (3) minutes. With this system, the reel set changeover is significantly sped up and made more flexible, which can take a lot of time in other sheeters.
• Operators can work during this process with the utmost safety.
• Format changeover is fully automated. The sheeter will make all the required movements for changing format automatically, thus drastically minimising its downtime, and is capable of performing order changeovers fast and reliably.

Pasaban and the Koehler Group have executed a project that has led to the installation and commissioning of the most productive and flexible sheeter in the current carbonless and fine paper industries. Both work groups have collaborated efficiently in the commissioning of this KB2160 sheeter having six automatic unwind stands.
Once again, setting the market’s standard.
