Converting of high quality coated board grades. A fully capable rotary die cutter is an available option. All common sealing methods are possible: Glue, tape, stitch as well as combination sealing options. One color and multi-color jobs, even in small order sizes can efficiently be run. Highest accuracy slotting an die cutting assure precise folding for perfectly produced packaging.

The following key questions are answered in this module: In what order does a flexo folder-gluer perform its operations? Typically, a flexo folder-gluer performs its functions in the following order: blanks are fed one at a time; printed with one or more ink colors; scored, slotted and trimmed; glued and folded; and counted and stacked.
How are the sheets of corrugated board fed one at a time into a flexo folder-gluer? Blanks can either be pushed or pulled into a flexo folder-gluer using a kicker-type feeder, a suction-type feeder, or a combination. Feed or pull rolls accelerate each blank as it enters the machine to create the required spacing between the blanks. When more than one color is to be printed, how is the order of application determined? Because the inks are somewhat transparent and the printed surface becomes less and less absorptive, darker colors are usually printed first and lightest colors last.
Why is it important to continuously agitate flexographic inks, even during short down times? Flexographic inks tend to thicken as they are agitated until they reach a stable viscosity.
Continuous agitation maintains their viscosity and and also avoids drying of the inks in the pans and circulating systems. How can adjustments and maintenance be performed on the different sections of a flexo folder-gluer? Rollout and rollaway models allow for easier access to the sections. In rollout machines, the printing and die cutting sections can be rolled out to the side, while in rollaway machines, the sections are mounted on rails and remain inline when they are separated.
Sample Video Transcript Below is a transcript of the video sample provided for this module: Although different equipment manufacturers have slightly different designs, the same basic operations occur in all flexo folder gluers. The blanks are scored across the flutes at the corrugator. Before they reach the flexo folder gluer, these scores help create the box flaps.
Then, at the flexo folder gluer, the blanks are fed into the machine one at a time at the feed section. From the feed section, the box blanks travel to the printing section, where they are printed. Next, at the scorer slotter, each blank is scored in the flute direction and slots are cut to complete the box flaps.
The box blanks are shipped to the customer in their knocked-down or flattened state in order to save space. Click here to view your cart.
