The fabrication process of plate rolling is when metal is passed through a pair of rolls to thin out the material.   It can either be hot rolling (metal is rolled at temperatures above the recrystallization temperature, which is anything done with heat) or cold rolling (metal is rolled at temperatures below recrystallization temperature, which is at room temperature or near room temperature).   The rolling machines that cold roll, do not expend any energy to heat the material. The whole process is done at room temperature and this saves energy. There are various types of rolling process including controlled rolling, roll forming, profile rolling, roll bending and ring rolling.  A basic roll forming machine has four major parts to it. The first is the entry section where the workpiece is placed. The second is the station rollers, where the material is bent by moving through them. Next, the cut off press, where the material is cut to the specified length. The last part of the machine is the exit station, where the final piece exits the process and is moved.

Plate rolling machines involve multiple forces and multiple directions of inertia during the operation.  Four-roll plate rollers are the fastest and produce the most accurate bends. This machine has the plate securely locked in place between the top and bottom rolls.  A three-roller machine has one pressing top roll and two pressing side rolls. The top roll will move in a vertical plane while the side rolls move on the horizontal plane. 

The four-roll machines do not need the material to be flipped or altered after pre bending.  The material stays inside of the machine and this allows the material to be formed directly after pre bending.  Four-roll machines require the pit to be constructed to working level because the material is loaded parallel to the floor.  Three-roll, Variable-geometry machines are best used for medium to thick materials. The upper rolls will move up and down, while the lower rolls will move horizontally from right to left.  Three-roll, double-pinch machines also do not require anyone to flip the material after pre bending.

These rolling machines may work with several different types of materials and this may affect how the machine performs.  Crowning is used to help adjust the rollers to correct any kind of deviation from the plane. If you do not have sufficient crowning, you may end up with workpieces that are unsatisfactory.  With all things being equal, optimal crowning is 75% of nominal capacity.
