Window patching

Window Patching Machine

Sometimes there’s no substitute for seeing what’s inside the box. But placing and gluing a rectangular patch of window film in precisely the right spot over a cutout on a folding carton It can be a perfect solution, both for functional reasons (so the product does not come into contact with the carton) and for aesthetic reasons (so the product is visible). Here how it’s done.

• Die-cut cartons are fed print side down through the window machine.
• A pattern of adhesive is applied to the carton blank
• The roll of window material is unwound and cut to length
• This “patch” is transferred to a vacuum cylinder
• At the precise moment, the vacuum is released and the patch is compressed onto the carton as it passes below.
