Roberts PolyPro Gives Converters A Clear Window of Opportunity

Mar 19, 2003

CHARLOTTE, NC - Roberts PolyPro Inc., an innovative leader in packaging and converting solutions, will unveil their new high-speed In-Line Windowing Applicator at CMM, Chicago April 14-17, booth #1020.

The newly designed In-Line Windowing Applicator applies windows to folding cartons with extraordinary speed and precision. The modular unit can be directly integrated with existing folder/gluers, thus eliminating handling labor. It has single lane in-line speeds of 36,000 to 50,000 per hour depending on carton size and pitch.

"This machine was developed because current windowing systems are generally slow and labor intensive. Window applicators and folder gluers are separate production processes involving needless product handling and excess work-in-process. Our new windowing applicator eliminates all of that," says Allan Sutherland, President.

The In-Line Window Applicator offers numerous benefits not currently available with traditional off-line windowing systems. Quality is improved by reduced handling and the use of fast setting glue eliminates window stickers. Also, the system applies the adhesive to the window, not the folded carton, thereby effectively reducing adhesive application speed and eliminating problems associated with dust build-up, misfeeding of cartons and other commonly occurring problems with traditional window systems.

Some of the features and benefits of the new Window Applicator include:

  • In-line system eliminates multiple unnecessary handling and labor cost compared with off line systems.
  • Adhesive application is designed for instantly curable adhesives.
  • Adhesive is applied to film at film speed rather that to the carton at carton speed using anilox roll/print technology.
  • All individual components such as vacuum drum, knife roll, print cylinders and film metering are driven by servo motors allowing for on-the-fly phasing and easy setup.
  • Make-readies are simplified with recipe selection from operator interface terminal.
  • Integrated web aligner, Coast Controls All Air Guiding System is standard.

Roberts PolyPro produces window application systems that can apply a full range of window sizes to folding cartons and feed the cartons directly into a folder/gluer. A window system version is available to run a double sided window carton in a single pass.

The Window Applicator is part of Roberts Polypro line of converting machinery, engineered to dramatically increase throughput with less labor and maintenance and increased operator safety.

Roberts PolyPro produces a modular line of converting machinery, as well as a comprehensive line of handles, spouts and other value-added components. For more information about Roberts PolyPro, call 704-588-1794, send them a fax at 704-588-1821 or visit their web site at
