Duplex Long Folder Slitter

SWI Machinery Introduces the Latest in Sheet Metal Machinery, the Duplex Long Folder Slitter

SWI Duplex folders are way ahead of the competition.

When designing the Duplex, we listened to what our customers wanted from an up & down folder. We listened to what they didn’t like about other machines on the market. The Duplex eliminates the inefficiencies seen in other up & down folders through intelligent design and incredible ease of use. Those of us who have used the SWI Duplex know that it’s easier to use than any traditional long folder.

We tested it with real flashings from one of the largest roofing companies in Australia. We now know that the SWI Duplex has at least 57.7% more capacity than a traditional long

folder. In one test, we achieved 82.2% capacity improvement.

SWI’s latest model Duplex folder incorporates dozens of advancements in control and mechanical design, making them the preferred choice of the world’s largest and smallest roofing fabricators stat include Kingspan in Europe and Metal Sales in the USA.

With the seemingly endless race to make folders move faster and faster, SWI has taken advice from Europe’s most experienced safety experts to engineer a machine that provides exceptional throughout with movements limited to sensible speeds that are less hazardous to operators.

Furthermore, our Duplex folder is the ONLY sheet metal folder to have been given the European CE approval by independent TÜV Nord Certified Machinery Safety Experts from Pilz. SWI’s CE Certification is underwritten by Pilz Europe.
