The Vertical Cartoning Machine works with sleeve-style cartons. These are usually die-cut and scored sheets of paperboard or corrugated material and, in some situations, plastic (PVC materials are most common) that have been folded and glued along a side seam to form what amounts to a knocked-down sleeve. The cartoning machine pulls each knocked-down sleeve out of a supply magazine, typically via vacuum, then erects and presents these opened cartons to the product-loading station(s) of the machine.
Vertical cartoners that handle sleeve-style cartons, unlike horizontal machines, erect and position cartons in a vertical orientation for loading. This style is ideal for loading multiple loose products (granular products, fasteners, bite-size candies, etc.) with the aid of gravity.
Whether the product is loaded manually or automatically, the loaded cartons are transported ahead for the automatic closure of both ends. Carton closure is typically accomplished by glue sealing or with a tuck-in flap closure. Heat-sealing or hot-air-activation closure methods also can be used, provided there are preapplied adhesive strips or some type of polysubstrate on both sides of the carton.
