Sonoco Capped End Revives Cores Wars

Article excerpt

NEWSPRINT ROLL CORE makers market their products in an unusually round-about way: They try to get newspapers interested in the core in hopes the papers will pressure their real customers, the paper mills.

"We're going after the end user and then our customer, the mills And if you know mills they won't change anything unless their customer tells them, 'You've got to change,"' Newark Paperboard Products' Bill Barrett said while pitching Greensleeves cores on the show floor of the recent Nexpo in Orlando.

So does this approach work?

"Absolutely," said Lynn Roper Jr., paper mill core product manager for Sonoco Products Company "We are much more involved with the printer than we were, let's say, 15 or 20 years ago.... Newspapers are measuring everything for performance, including the cores -- and we hear about it."

Coming to trade shows such as Nexpo, Roper said, "helps to generate conversation."

Indeed, Sonoco and Newark are generating considerable heat with aggressive marketing campaigns that have set off a kind of Core War.

Both make cores designed for the Goss CT 45 and 50 reelstands, which changed the rules for newsprint rolls when they were introduced more than a decade ago.

Newsprint roll diameters increased significantly, requiring a core that could stand up to the side-to-side pressures core-makers call "axial crush." On the press floor, that meant if a core could not take the pressure, the web would begin to wiggle and shimmy in the press -- throwing off register and increasing web breaks. For publishers, had cores could translate into poor quality and missed deadlines.

With the introduction of the CT 45/50, chucking also changed -- and changed again more recently The issue of how cores fit into the reelstand has emerged as the biggest battlefield in Core Wars.

Sonoco fired the most recent shot with the introduction at Nexpo of the Ultra CPC-B. Though beveled at the end like its CPC predecessors, this core, unlike other Sonoco cores for the 45/50, for the first time has a metal end or cap. A big recyclability claim of Sonoco for its 45/50 cores had been that the core was entirely fiber.

Sonoco's Roper says the cap was added because of runnability problems with newer -- and smaller -- chucks now on the Goss reelstand. In addition, the beveled plain fiber-end core required careful mounting and, therefore, more training than some press operators ever got. …
