  Rolling - Wikipedia, the free encyclopedia
Rolling is a combination of rotation of a more or less cylindrically or spherically symmetric object, and translation of that object with respect to a surface (either one or the other moves), such that the two are in contact with each other without sliding.
Rolling of a round object typically requires less energy than sliding, therefore such an object will more easily move, if it experiences a force with a component along the surface e.g.
dice, roll by successive rotations about the edge or corner which is in contact with the surface.

 Hot rolling - Wikipedia, the free encyclopedia
Hot rolling is a metallurgical process in which the metal is passed through a pair of rolls and the temperature of the metal is above its recrystallization temperature, as opposed to cold rolling, which takes place below it.
Hot rolling is mainly used to produce sheet metal, or simple cross sections from billets.
Hot rolling is primarily concerned with manipulating material shape and geometry rather than mechanical properties; This is achieved by heating a component or material to its upper critical temperature and then applying controlled load which forms the material to a desired specification or size.

 Rolling bolsters bolster productivity   (Site not responding. Last check: 2007-10-23)
With this equipment, the operator rolls the bolster out of the press, unbolts it from the bolster, removes it with a crane, sets the new die on the bolster and bolts it, and rolls the new bolster into the press–all within 10 to 15 minutes.
In this case, bolster 1 rolls out of the press with the old die and moves sideways to allow bolster 2 to replace it in the press with the new die.
Rolling bolster systems used to be installed only in presses larger than 800 tons because cost was prohibitive when compared to the cost of the press itself.

 Rolling Mill Printing for Jewellers
The rolling mill is used for reducing the thickness of sheet metal.
The rolls for wire are cut with 'v' shaped grooves arranged in decreasing sizes, allowing for gradual reduction of wire diameter and producing a square cross section of wire.
Rolling wire in a paper sandwich gives slightly raised edges to the wire which now has a soft paper texture and is broadened.

 Rolling (from metallurgy) --  Encyclopædia Britannica
More than 90 percent of the aluminum, steel, and copper produced is rolled at least once in the course of production—usually to take the metal from a cast ingot down to a sheet or bar.
Rolling is the most widely used method of shaping metals and is particularly important in the manufacture of steel for use in construction and other...
The Rolling Stones, named after a Muddy Waters song, were formed in London, England, in 1962 and by the late 1960s called themselves the World's Greatest Rock and Roll Band.

 Metalworking Fluids and Lubricants   (Site not responding. Last check: 2007-10-23)
UCON metalworking lubricants have been successfully used by formulators as the lubricity base for water-soluble cutting and grinding fluids.
UCON metalworking lubricants feature inverse solubility, which means that a material becomes less soluble in water as the temperature of the solution increases.
When a UCON metalworking fluid comes in contact with the hot tool and workpiece, the polyalkylene glycol comes out of solution and coats the metal surfaces with a concentrated lubricant film.

 Society of American Silversmiths - Glossary
The sandwich or "billet" can also be forged without the use of the rolling mill.
Britannia metal was often spun; a typical, modern spun object is the aluminum saucepan.
As in most metalworking techniques, the metal is periodically softened by annealing, or heating, when it has become hardened through being worked.

Rolling is accomplished by repeatedly passing the material backwards and forwards through machine (between side rollers and winding handle roller).
As this is done, a gradual increase of pressure on the main handle tightens radius on each pass through machine.
