It is the word that is used by the extension for a flexible bags that volume can be changed by the compression or expansion.They are not used to deliver air such as the light and tight and the bag which allows the distance between the lens and film of a folding photographic camera that is to be varied , which is termed as flexible bellows.
METALLURGY:
Some processes such as metallurgical iron smelting and welding that is required so much of heat that they could only be developed after the invention and in antiquity of the bellows.Although , the bellows are often used to deliver additional air to the fuel with raising the rate of combustion and gives rise to the heat output.
There are various kind of bellows that are used in metallurgy which are as follows:
BOX BELLOWS:
In Asia , there use are traditional.
POT BELLOWS:
