Whenever repeatability, productivity and ease of use are of essence, the 4-roll is the technology of choice. In a 4-roll machine, latest development of the rolling technology, the bottom roll clamps the plate guaranteeing a perfect control over its position throughout the whole forming process. The side rolls, actuated by the unique DAVI planetary guides technology, provide the necessary bending force achieving the tightest diameters per capacity on the market (1.1 of the top-roll) obtaining the highest accuracy thanks to the perfect parallelism offered by the patented Servo-Tronic© system. Compared to other technologies, 4-roll machines stand out for allowing fully CNC-automated production processes, significantly decreasing the reliance on operators’ skills and, hence, making it the most suitable tech for mass-production.

Introducing Davi’s 4-roll plate rolling machine, a state-of-the-art technology that excels in repeatability, productivity, and ease of use. This advanced machine features a bottom roll that clamps the plate, guaranteeing precise control throughout the forming process. The side rolls, powered by Davi’s planetary guides technology, provide exceptional bending force, achieving the tightest diameters in the market. The patented Servo-Tronic© system ensures parallelism of the rolls at all times, even in the event of electronics failure. With its compact and closed frame, customizable options, enhanced operability, and reduced maintenance requirements, Davi’s 4-roll machine is a top choice for mass production and various industrial sectors.

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  thickness, up to 80-100 mm , and more, it is recommended for limited production volumes.

The Davi 3-roll variable-axis plate rolling machine is a flexible and accurate tool for plate bending. It features motorized rolls, precise positioning, and a sturdy frame for enhanced performance. The tilting rolls enable precise cone bending, while mechanical and hydraulic symmetry ensure improved tolerances and load distribution. With the patented Servo-Tronic© system, rolls parallelism is maintained, and the multi-gearbox configuration enhances operability and maintenance. Davi machines are reliable and efficient for plate bending applications.

WHAT IS A PLATE ROLL? | Engineering Machinery | #knowledgelab

A Plate Rolling Machines is a bending machine that transforms a flat sheet of steel into a circular cross-section, typically named a shell or can. The shell can be used to build tanks; boilers and a huge number of different others circular containers. The plate roll can be made with two, three, or four rolls, and the bending process is performed by inserting the sheet inside the rolls. After having pinched the sheet with the rolls, and rotating the rolls, to feed the sheet, the circular can is made. The position assumed by the side rolls estabilish the diameter of the shell.

Plate Rolling Machines – 3 Rolls Plate Machine | 4 Rolls Plate Machine | NC & CNC Controlled Plate Machines.

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.
