Plate Rolling

Born in Italy in 1966, DAVI is the world's largest manufacturer of Heavy-duty plate rolls, Sheet rolls, Sheet bending machines, Heavy-duty angle rolls, high productivity lines, and customized rolling machines. Its leadership is evident with regards to sales volume, employees, production, assets, and rating. DAVI also owns the highest number of patents in the industry.

DAVI product portfolio includes the widest range of heavy-duty plate rolls (both 3 and 4 rolls), for plates from 2 to 6m width and 6 to 400mm thickness; high productivity 4 roll and robotic lines, for plates from 1 to 6m width and from 2 to 15mm thickness; customized machines for tank trailers, aircraft, aerospace, shipyard sectors, for plates from 6 to 24m width and beyond.

Davi offers both 3 Roll as well as 4 roll Plate rolling machines. In 3 roll machines, Davi offers the MAV version, which is the Variable geometry Rolling machine, and MCO which is the 3 roll Double Pinch Rolling machine.

In the MAV, the side rolls can be moved in and out independently, optimizing the geometry for any application. Positioning the side roll to reduce the flat-end, results in the shortest flat-end for any thickness, thanks to the “variable” geometry, vs. any other “fixed” geometry 3 roll plate roll. Opening completely the side rolls, increasing the bed, the machine can form much thicker plates than any other roll in the industry. Moving independently all three rolls allows the best geometry for any angle of the cone. This is the most advanced plate roll for thickness greater than 60-80 mm,(2 – 3 Inches). A machine apart, with many exclusive benefits, the best solution available in “super heavy applications”.

Whereas the MCO , offers the most common design in the industry, with the top roll fixed, and the two side rolls that move up and down to pre-bend the edges, and to roll the plates. The most inexpensive roll for plates from 15-20 mm (5/8 – 3/4 inches) thickness, up to 80-100 mm (3 – 4 Inch), and more, it is recommended for limited production volumes. The MCO is called “double pinch” because it performs the pre-bending of both ends of the plate without removing the material from the machine (impossible on any single initial pinch, asymmetric design). As the side rolls widely raise and drop to pre-bend the two edges, the large free access allows to form high stock bar through the rolls, compared to other roll designs.

In the 4 roll models, DAVI offers 2 versions viz MCA and MCB .

The MCA version is innovative and exclusive in design, to roll plate up to 10-15 mm (1/2 inch) thick. Accurate, fast, easy, and intuitive, it is the most high-tech plate roll for “light gauge” in the market. The machine is controlled, by an entry-level, user-friendly CNC, to roll parts in automatic mode. More powerful DAVI CNCs controls are self-programmable, without the need for experienced operators.

Whereas the MCB offers the most advanced machines to roll plates from 15-20 mm (5/8 – 3/4 inch), up to 80-100 mm (3 – 4 inch) thick, and more. Accurate, easy, intuitive, and fast (up to 6 meters – 20ft per minute), it is the most high-tech in “high productive mid-heavy application” in the market.

‘Always on time’ is one of the mottos that distinguishes DAVI, a company that can claim almost 10,000 machines installed all over the world, has an 11,000 OEM parts and components warehouse to feed its massive production, builds 300 machines per year, and always keeps 100 machines ready for immediate delivery, even those for heavy industries. These are some of the reasons why DAVI can offer the shortest delivery time in the market. DAVI is proud to keep its supply chain always 100% Made in Italy, selecting the best suppliers (all ISO certified) for every specific product.
