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.
A box barrage could also be used to prevent the enemy from reinforcing a position to be attacked. In a trench raid of March 1917, the 1st Battalion the Buffs were supported first by a creeping barrage, then by a box barrage once they were in the enemy trenches, to prevent German reinforcement or counter-attack.

When rolling, the top roll presses the metal plate between the two side rolls. The advantage of having the variable three roll is the ability to roll many thicknesses and diameters of cylinders. For example; The side-rolls are what produce the mechanical advantage. With the side rolls all the way open, one has the maximum mechanical advantage ...
