Successful start-up of Wuzhou Special Paper’s new winder with Valmet Perforating Splicer
On April 2, 2026, Wuzhou Special Paper successfully started up its new Valmet-supplied winder. The high‑capacity winder, equipped with advanced automation features and Valmet’s new innovative splicing technology Perforating Splicer, will meet the demanding speed and quality targets of the PM 19 production line. This start-up is continuation of the strong and steadily deepening partnership between Valmet and Wuzhou Special Paper, marked by multiple repeat orders and successful projects.
"We are pleased to announce the successful start-up of the winder for the PM 19 production line. We would like to express our gratitude to the project teams of both parties for their efficient coordination and close collaboration. Importantly, this winder features Valmet’s newest Perforating Splicer technology. Leveraging this pioneering technology and advanced automated features, we expect the PM 19 production line to achieve its targets and reach its design capacity and speed at an early date," says Yanchen Zhang, Deputy General Manager of Wuzhou Special Paper Group.
Boosting efficiency with advanced splicing technology
In addition to the winder, Valmet supplied a novel Valmet Perforating Splicer for the PM 19’s winder. This innovation enables the use of a single winder in the production line and is designed to significantly speed up parent‑roll changes, helping the mill to increase throughput and overall efficiency. With this adhesive-free splicing method, the webs are mechanically perforated and interlocked, resulting in a stable lap joint without any glue or tape. This new splicing technology helps Wuzhou maintain the demanding production efficiency targets of the PM 19 line.
With this new splicing technology, the splice is created by connecting the webs with a perforating tool without any additional glue or tape materials.
“Our new Perforating Splicer represents a real step forward in high‑speed winding performance,” says Kenneth Åkerlund, Senior Manager, Reels and Winders, Valmet. “By enabling fast parent‑roll changes and eliminating the need for glue or tape, it boosts capacity while reducing operating costs. The mechanical interlocking of the webs ensures a stable, reliable splice. For a fast-running machine like PM 19, the ability to perform quick and stable parent roll changes is essential, and this solution gives Wuzhou the performance they need as their production continues to grow.”
Successful start‑up reflecting years of close cooperation
"In recent years, Wuzhou Special Paper has built a good partnership with Valmet. For the PM 19 project, our project team and Valmet’s team worked hand in hand throughout the entire process from defining technical solutions and signing the contract, to on-site execution and successful start-up. While we faced challenges along the way, the two sides maintained smooth communication, ultimately ensuring the project’s success,” says Xiaojun Guo, Project and Production Manager, Wuzhou Special Paper.
“We are extremely pleased with the successful start‑up of the winder, and it clearly reflects the strength of our cooperation with Wuzhou. From early planning to commissioning, the project has been driven by open communication and a shared commitment to performance. Seeing the winder running smoothly from day one is a proud moment for both teams and a great example of what close collaboration can achieve,” says Min Zong, Project Manager at Valmet.
Technical information about the delivery
Valmet’s delivery included an OptiWin Drum two-drum base winder with automatic functions such as set change with core and tail gluing and slitter positioning. It is additionally equipped with Valmet Perforating Splicer which improves capacity with fast parent-roll change. The delivery also included spare parts packages and digital services with connectivity.
