Since the discover by ancient peoples that metal can be liberated by applying heat to rock ore, methods for extracting and
manipulating metal materials have been rapidly refined. The interest in metal working is sparked by modern society's need for
metal products and tools. It seems like everything from household tools to automobiles and skyscrapers are products of metal
forming. Today's population has become dependent on metal to complete daily tasks and function in society. For that reason,
metal forming has become and increasingly important trade.
Roll forming is one method of metal forming. It is important to note that rollform can be written as either one word or separated
into two words. These two forms of using the word "roll form" will be used interchangeably throughout this article. The art of
roll forming is a continuous process. A roll forming machine consists of several sets of consecutive rolls. Each set of rolls is
called a stand. As the metal passes through each stand it is only bent slightly. Therefore, each stand only incrementally contributes
to the desired specification of the metal. The metal piece will continue rolling through the roll forming machine, being manipulated
by each stand, until it reaches the desired cross-section profile. The practice of roll forming is best used when making parts with
long lengths. Roll forming is a common way to form objects out of sheet metal.http://www.soocuu.com/

A roll forming machine will shape a piece of metal into a specified cross-section profile. Simply put, a cross-section profile
refers to the desired result, in other words, the concluding shape of the metal. A variety of cross-section profiles can be
obtained through roll forming. Each desired shape, however, will require a specifically crafted roll tool. For example, on roll
forming machine cannot produce a variety of differently shaped metal. One machine will produce a specific form. If another
form is desired a new carefully crafted set of roll tools will be required. It may seem silly to possess a machine that only
shapes metal into one form. One must remember, however, that roll forming machines are intended for industrialized purposes.
Factories such as automobile plants or factories that produce aluminum cans require machines to make the same bends in the
metal without requiring change. http://soocuu1.spaces.live.com/
