Water-Jet Turn-Up System

The Reel-Jet™ is a water-jet turn-up system designed for a wide range of products such as tissue, printing, coating, containerboard, linerboard, kraft, pulp and specialty grades for operation on most reel types and paper grades. The turn-up system offers selective cutting profiles such as cross-cutting for heavy grades, parallel cutting for lightweight tissue grades, and other specialized methods to improve reel turn-up efficiency, therefore, minimizing spool core losses.

Given the technical challenge, the turn-up system performs with a high degree of reliability. The turn-up system must start and end the cutting process within a span of a few hundred milliseconds. The turn-up system process starts with the initial chevron-shaped tip adhering to the spool cleanly and once the symmetrically widening web is wound around the spool, the subsequent layers are distributed evenly and without folds until the full web width is rolled up. The entire turn-up system process unfolds without mechanical shock load, dusting, or an undesirable loss of paper on the spool. Compared to a tape turn-up system, there are no tape imprints in the water-jet turn-up system process.

The high-pressure water-jet contains sufficient energy to cut any basis weight reliably. The high-pressure water passes a diamond nozzle to produce a laminar, cohesive jet of ultrasonic speed. Yet the amount of water sprayed to the surface of the pope roller is small enough to leave no trace, nor damage its surface.
