What Are 4-roll round bending machines?
Plate Roll machines or sheet metal bending machines are used for bending sheet metal webs and are divided into different types by the number of rollers installed. The 4-roller round bending machine is one of the designs and is often considered a good choice for entry-level plate rolls.
The four rollers consist of an upper and lower roller and two side rollers. The sheet metal that is being bent is clamped and guided with the help of the top and bottom rollers. Finally, the two adjustable side rollers exert the necessary bending force on the sheet. How the rollers can be adjusted varies from design to design. The 4-roll plate roll is ideally suited for bending tight radii.
