Inspection Rewinds Step Up to the Plate

October 2005
Operators can do more with less with inspection rewind systems.

BRING UP THE subject of inspection rewinds and people don't automatically think Derek Jeter—for obvious reasons. But a closer look reveals it's not as far-fetched a comparison as some might believe.

Jeter, the New York Yankees' short-stop, has earned several accolades for his all-around ball playing ability. He earned 1996 American League Rookie of the Year, 2000 World Series Most Valuable Player, 2000 All-Star Game Most Valuable Player, and 2002 ESPY Play of the Year. He's not flashy or cocky, but he's turned heads during his 10-year career for his consistency and aptitude, carrying a career fielding percentage of .975 and a career bating average of .314.

Inspection rewinds aren't full of razzle-dazzle either, but they are the all-around, can-do-it-all equipment of the package printer. They do everything from rewinding rolls and inspecting webs to slitting, counting, and diecutting—on a consistent and high-quality basis. In some cases, inspection rewind features help companies expand the range of substrates they can handle, as well as open up new finishing techniques to their customers.

One example of this is how today's new and improved inspection rewind systems equip converters and printers with the ability to handle all kinds of packaging materials. As brand owners turn to new and unique film substrates to help with product differentiation, their business partners have to have equipment that can offer better control of the web during the inspection rewind process.

According to Nick Knezic, sales and marketing manager, KOR Engineering Inc., slippery and extensible substrates like unsupported films and clear-on-clear labels, call for better motor drive and tension control systems. With this point in mind, KOR Engineering recently refined its inspection rewinders to help label converters and printers extend their offerings to include flexible packaging, Knezic said.

Another significant improvement in inspection rewind equipment has come by way of better embedded micro controller-type technology, said Ron Suenram, product manager - web guiding & inspection, Fife Corp. "The embedded micro controller has greatly improved over the last several years," he said. "These improvements have allowed better image processing, which has enabled us to move away from PC-type technology. The benefit with embedded micro controller-type technology is that you have more control over design. As we all know, PC-type technology is heavily influenced by Microsoft and Intel, which can change several times over the typical life of a product. These changes make product support and backwards compatibility very difficult and/or next to impossible for suppliers of video web inspection systems."
