How exactly does a rolling mill work? - Practical Machinist

By placing the sheet of metal on a flat surface and putting weight on top of it you would be applying pressure. By forcing the sheet metal between two rollers being 1/16" apart, the 1/8" thick sheet would try to force those rollers apart, but since the rollers refuse to move apart they are opposing this pressure simply by not moving.
