New high-speed decorator from CMB
The can decorating machine has been engineered to produce flawlessly decorated beverage cans at high speed. It is designed to reduce changeover time for can manufacturers who produce high volumes of cans in short runs while minimising spoilage and saving ink.
The Sovereign Decorator uses up to eight colours to enable beverage can manufacturers to offer brand owners more sophisticated and distinctive designs than ever before. Using unique, oscillating rubber rollers the decorator offers smooth and even printing. The print rollers’ oscillating speeds can be individually fine-tuned to allow the inkers to work with any ink colour or viscosity. The Sovereign Decorator has an innovative linear bearing spindle disc design that applies consistent mandrel-to-blanket pressure to the can surface during the printing process, maintaining a high print quality. The decorator inkers also feature anti-ghosting rollers, eliminating the occurrence of ghosted images.
For added flexibility and efficiency on the production line, the Sovereign Decorator features an innovative infeed and outfeed design that improves the loading and discharge of cans, increasing throughput speeds and simplifying can size changeovers for operators. The rollers can be programmed for new inks and graphics using a library of printing recipes to facilitate fast, straightforward label changes. Operators can adjust printing programs and label registration while the machine is running, further minimising production downtime.
The Sovereign Decorator has several features to reduce ink and spoilage. If the can is not correctly aligned, the automated rejection system removes it from the production line before the printing process, minimising the number of incorrectly decorated cans. The system’s new, pneumatic single mandrel trip ensures that only the substandard can is rejected, further reducing spoilage for beverage manufacturers. The Sovereign Decorator’s innovative ductor rolls, which take the ink from the fountains to the printing system, are fully adjustable according to the amount of ink required for a design.
Rather than using gears in the inker drives the Sovereign Decorator uses belt drives, which require no lubrication, eliminating oil leaks, and reduce vibration.
“It’s no question that the marketplace for beverages is fiercely competitive, and cans are a hugely popular packaging format. Until now, beverage can manufacturers either had to sacrifice print quality for speed or efficiency for superior aesthetics. The Sovereign Decorator changes that, letting our customers have the best of both worlds,” says Jim Cozier, general manager, CarnaudMetalbox Engineering. “Through our engineering skills, and research and development programs, we were able to bring this machine to market to give can manufacturers the flexibility and high quality required to consistently meet their client needs.”
