Providing a change in paper and board winding and unwinding processes

The new technology offers significant runnability improvements for paper and board reels in the most demanding winding operations, especially in centre drum winders and special unwinding stands like sheeters as well as corrugators.

A new generation of chucks

“To meet today’s challenges of paper and board manufacturers and to offer significant productivity improvements in a cost inflation environment, we developed a new generation of chucks exclusively with our partner,” said Markku Ronnila, product manager paper mill cores in Europe. “Our new chuck technology is a step change in paper and board winding and eliminates typical problems such as vibration, torque transmission issues and chew-out. We called this innovative technology ViPer Chucks in reference to the improved vibration performance.”

Significant process improvements

ViPer Chucks offer significant process improvements during winding runs, less vibration leading to reduced web-breaks or web-tension, overall faster winding speeds and reduced chew-out causing less abrasive dirt. Consequently, this avoids frequent chuck cleaning and saves employees’ working time. The chucks also provide better torque transmission for heavy reel weights. The result allows for higher productivity due to significantly reduced process interruptions coming along with an improvement on process safety. Existing chucks can be easily replaced in a plug-and-play solution.
