About The DJJF Dual Fully Automatic Surface Rewinder
Simply put, the DJJF is the equivalent of two JJF rewinders combined into one system. As with the JJF, the DJJF requires minimal operator involvement to keep both machines running in a fully-automatic mode. By sharing a few common components between the two rewinders, production becomes twice that of a single JJF unit. This significantly reduces a converter’s overall investment, labor requirement and production floor space.
The DJJF can be customized or retrofitted with Jennerjahn’s patented coreless technology allowing converters to maximize their initial investment.
Applications
The DJJF slitter rewinder is utilized in the highest volume applications where full automation is necessary. By sharing a few common components between two rewinders, production becomes twice that of a single JJF unit. This significantly reduces a converter’s overall investment, labor requirement and production floor space. The JJF can be used for a wide variety of converted products: point of sale, ATM, lottery ticket, airline boarding passes, pressure sensitive labels and many more.
Operator Responsibilities Per Cycle
None!
Automation
Cores are automatically fed into a sorting unit where they are aligned and staged in the autoloader. The machine inserts the cores into the rewinding station, cuts the tails, wraps the tails around the cores, tucks the tails, winds the roll to the desired length, transfers the rolls to the seal station, seals the tails of the finished rolls, transfers the rolls to an exit conveyor and conveys the rolls outside of the machine.
