Meixin Water-Jet Turn-up: Principle & Benefits

As paper machines continue to operate at ever-higher speeds and wider web widths, automated reel changing has become an essential requirement for modern paper manufacturing. Traditional manual reel turn-up exposes workers to severe safety hazards and generates substantial quantities of paper waste at the spool bottom, directly restricting production capacity, operational stability, and finished product quality. The Meixin Water-Jet Reel Turn-Up System delivers an advanced, fully automated solution engineered to solve these long-standing industry challenges. The system seamlessly integrates ultra-high-pressure water cutting with precision adhesive transfer. Installed on a main beam positioned above the paper reel, a dedicated ultra-high-pressure pump station delivers high-energy water streams through specialized nozzles. Two traversing nozzle assemblies move rapidly across the web to execute precise, clean paper tail cuts, while a synchronized metering glue pump unit applies an optimal layer of adhesive onto the newly cut paper tail. As the treated tail reaches the new empty reel spool, it adheres instantly and spreads flatly across the full web width, realizing a smooth, high-quality turn-up without stopping or slowing down the paper machine. Beyond technical performance, the system delivers substantial practical and economic benefits for paper mills. Full automation completely removes workers from high-risk operational zones, significantly elevating workplace safety standards. Field-proven engineering yields an exceptional turn-up success rate exceeding 99.5%, ensuring continuous and stable production runs. Furthermore, rapid paper transfer secures the web flatly against the new spool, preventing bottom-layer wrinkles and eliminating unnecessary paper waste. Controlled via an intelligent PLC system, the equipment easily adapts to diverse paper grades, including corrugated paper, kraft paper, duplex board, newsprint, and tissue paper. In terms of financial return, the finished product yield rate can rise by 0.5% to 3.0%. By minimizing scrap paper and maximizing saleable output, this single capital investment generates continuous operational savings, enabling paper mills to achieve a quick payback period while pursuing higher capacity, lower material loss, and safer operations.
