New sustainable blade packaging

To decrease the carbon footprint of transportation of blades we have introduced a new sustainable slitter blade packaging made of 100% recyclable cardboard. The total weight of the box with blades is now less than 10 kilograms, while the old metal box weighs almost 25 kilograms. The lighter box increases the safety of the operators when lifting. Naturally, the new box is a more sustainable option compared to the old metal box.

The packaging is used for transporting, as well as for blade storage by the winder. The lighter box increases the safety of the operators when lifting and decreases the carbon footprint of transportation.

Valmet Slitter Holder Quick Change

Valmet Slitter Holder Quick Change is safer and faster than the conventional change methods. Further, it does not require any planned shutdowns.

Safe, fast and easy top slitter 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 roll and cutting quality
  • Less roll rejects, dust and fewer complaints from printing houses
  • 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.
