PFFC - March 2009 - (Page 38) SLITTER INSPECTION Brisbane facility. The company wanted to upgrade its slitting and rewinding capacities to handle thinner substrates without stretching. The Jupiter TC4 actually was recommended by Gallus after Hally failed in its attempt to upgrade one of its existing slitter inspection machines. Using the Jupiter TC400, Haley Labels now can convert substrates ranging from flexible packaging to cardboard and from paper labels to booklets. “We were looking for something that could run faster, but we had very specific requirements around the unsupported webs, using very thin films, and trying to run them at speeds without any stretch or tension issues,” explains Haworth, who visited Prati’s Italian headquarters to see slitter inspection equipment in operation. “We spent some time looking at the Jupiter TC400 and trialing material we had brought with us. When we came back, we decided we should have one.” Enhanced Productivity Perfect Roll Protection It’s like having a security force protecting your roll products 24/7. Plastic plugs up to 8" dia. Over 500 core plug sizes, styles and duty ranges! Basic roll protection starts with the perfect core plug. That’s where Badger Plug gives you more! More sizes … more shapes … more material choices … and more exacting tolerances.Your perfect core plug is only a phone call away. “Unsupported film is used for wrapping around the product with glue-applied [labels],” explains Tania James, operations manager. “Stretched film distorts the printed images and also creates dispensing problems, as the eye marks used by the machine change position. But the software-controlled rewind tension measurements on the Jupiter TC400 keep the material in constant web tension, preventing this stretching.” The Jupiter TC400 has three rewind tension measurements, keeping constant web tension. It also inspects for missing labels and waste, presenting all defects at the correction table. While rewinding, a constant tension on the shaft and variable tension on the substrate prevents conic distortion on the roll. “The other aspect for us was the ability to present cleanly finished and edged rolls,” says James. “Unsupported film has a tendency to take a variable web path because it is so light. On non-servo machines, you get a feathering of the edges on finished rolls. But with the Jupiter, Prati has been able to develop a smooth edge.” James estimates that since the Jupiter TC400 began operation, production speeds have increased by 30% –40%, which enhances productivity downstream. “It also handles the more difficult jobs we had trouble with before, such as perforations,” adds Haworth. “Because of the good tension controls on the machine, we can process them a lot faster as well.” uSupplier Infot uPrati srl | www.praticompany.com PFFC-ASAP 314 Nobody protects your rolls better!
