The mills normally make use of three types of rolls to progressively form the flat steel section into the round form prior to welding. The three types are: break down or forming rolls, the idler vertical closing rolls and fin pass rolls. ... Breakdown rolls provide the initial shaping of the strip towards the round form. ... The fin pass rolls provide perfect guidance into the welding section and in addition coin the strip edges to provide the precise circumference.[Source: The making, shaping and treating of steel, by the US Steel, p. 886.]  3, fiche 1, Anglais, - break%20down%20roll
