Slitter management for improved cutting process at tissue machines

Be smart, stay sharp - Slitter Management Program to secure an effective replacement process and continuous sharpness  

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 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, tissue makers can reduce costs and administration with increased cost predictability. It also reduces the customer inventory value and minimizes the yearly transactions from sourcing.

Safe, fast and easy top slitter change - Valmet Slitter Holder Quick Change   

Changing top slitters is traditionally complicated needing special tools, taking time, and causing hand injuries. Since Valmet Slitter Holder Quick Change was introduced to paper and board mills, our customers witness a safe, fast and easy slitter change:  

  • Minimum six times quicker slitter change than with the original holder 
  • No threads, screws or tools required 
  • Enables change of top slitter without planned shutdowns 
  • Improved cutting quality 
  • Less roll rejects and dust  
  • Top slitter release mechanism operates only when the slitter is not in the slitting position. The function prevents accidental release of the top slitter. 
  • Braking mechanism in the bearing assembly stops the rotation of the slitter and holds it in place when it is not in the slitting position

Slitter management services  

Additionally, needed amount of Valmet Slitter Holder Quick Change can be included to Slitter management agreement fee to avoid investment and to ensure the performance of cutting devices.  

We recommend a full mechanical winder audit to be performed annually. The audit helps identify winder issues beyond the slitter section, catching winding process problems before they snowball into larger issues. This service can be included in the slitter management program. 

Whether you are operating under a slitter management agreement or not, Valmet can supply exchange units or rebuild your existing equipment. This service is available for all Valmet slitting equipment.
