Window Film Applicator

The Roberts PolyPro Window Applicator applies windows to folding cartons with extraordinary speed and precision and can be connected directly into any existing folder gluer.

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. 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.

A window system version is available to run a double sided window carton in a single pass.

• In-line system eliminates multiple unnecessary handling and labor cost compared with off-line systems.
• Adhesive application is designed for instantly curable adhesives.
• Window system can be directly integrated with existing folder/gluers, thus eliminating handling labor.
• Adhesive is applied to film at film speed rather that to the carton at carton speed using anilox roll/print technology.
