Slitter management at board and paper machines was developed by Valmet to help our customers overcome winder problems such as poor slitting equipment condition, poor quality blades and bands, dull blades and bands, hand injuries and insufficient operator slitting process knowledge and abilities. Valmet Slitter management brings slitting best practices to your winder. Our services and technology include state-of-the-art blade design and materials, sharpness techniques, safe and easy slitter changes, and comprehensive OEM slitter section training.
Improved cut quality
Valmet Slitter Management Program is tailored to your needs. It includes the high-quality top slitters and carbide bottom bands with the hardened outer surface, superfinishing grinding of top and bottom slitters, automatic replacement of top and bottom slitters from a blade pool, slitter blade storage & transport boxes, and transportation to grinding and back. Further, the first installation of slitters is always conducted by our specialists.
The Slitter management program considerably reduces the maintenance costs, extending slitter blade life and blade change intervals, thus improving slitting performance. More effective winder operation improves the productivity of the entire line. With a fixed yearly fee contract, customer can reduce costs and administration with increased cost predictability. It also reduces the customer inventory value and minimizes the yearly transactions from sourcing.
Our customer Norske Skog Skogn reached several improvements such as less dust, better roll quality and slitting results as well as improved maintenance efficiency.
