It can be also called a “roll bending machine”, “plate bending machine” or “rolling machine”. There are different kinds of technology to roll the metal plate: Four-roller machines have a top roll, the pinching roll, and two side rolls. The flat metal plate is placed in the machine on either side and "pre-bent" on the same side.

A press brake is a type of brake, a machine used for bending sheet metal and metal plate. [1] It forms predetermined bends by clamping the workpiece between a matching top tool and bottom die. [2] Bending process A high-tonnage hydraulic press brake Liwei CNC 2000T 12M Heavy Duty model
This experimental machine was described by local papers as 'the world's first steamroller' and it caused a public spectacle. In 1867, the steam road roller was patented and the company began production of the first practical steam roller – the new machine's rollers were mounted at the front instead of the back and it weighed in excess of 30 tons.
Hydraulic machines use liquid fluid power to perform work. Heavy construction vehicles are a common example. In this type of machine, hydraulic fluid is pumped to various hydraulic motors and hydraulic cylinders throughout the machine and becomes pressurized according to the resistance present.
Rolling schematic view Rolling visualization. In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property.
