New Esko solution boasts 50% increased corrugated finishing productivity

August 12, 2019  By PrintAction Staff

Esko has introduced its latest Kongsberg digital cutting and creasing solution, the Dual Heavy Duty Unit, which it says can increase productivity by up to 50 percent in corrugated finishing.

The latest Kongsberg digital cutting and creasing innovation from Esko is designed to help corrugated converters cut, crease and perforate jobs without the need to change tools, boosting finishing productivity by up to 50 percent.

The newly launched Dual Heavy Duty Unit means operators no longer need to manually intervene in tool changes on Kongsberg digital cutting tables for those jobs that require creasing, cutting and perforation, Esko says. The machine is designed to automatically switch and use the right tool throughout the job, thus ramping-up production efficiency. As well, it combines, for the first time, two independent wheels in one heavy-duty unit.

The uniquely engineered design of a Kongsberg table makes it possible to exercise 50 kg of downforce on corrugated materials from single to triple wall, without compromising speed or quality, Esko says. The Dual Heavy Duty Unit boasts better crease quality, even on materials with a high recycled material content. When combined with the Esko CorruSpeed Tool, converters can cut and perforate corrugated substrates at full machine speeds of up to 100m/min.


The CorruSpeed Tool is designed specifically for high-speed digital finishing of corrugated board and is unique in that it uses a static knife in combination with a patented knife foot design to simulate the effects of ejection rubbers in conventional die tooling, Esko explains. The design, it says, results in cleaner, more accurate cuts without burrs, adding that it produces a crisp edge finish even at the highest speeds, smoothly cutting a variety of corrugated board types up to 7 mm double wall BC flutes.
