Cores, Shafts, and Chucks in a Digital World

Of course, there's another side to this viewpoint. But while other experts think cores, shafts, and chucks are impacted by this digital revolution, they say it has more do with how the equipment is manufactured than how the digital functions affect them on-press.

"In all web processes, continuous roll quality is an important part of web stability, production quality, and end-product quality," said Jeff Damour, engineering manager, Converter Accessory Corp. (CAC). "Shafts and cores are similar to a building's foundation. If the foundation is poorly constructed—not level or out of square—the entire building suffers. As the building goes up, the impact of the defects increase. The same is true with rolls. If the core or shaft is of poor quality, the roll may be defective.
