A fabrication process whereby the metal sheet is deformed continuously in a linear manner by passing it through a consecutive series of rolls which produce a predetermined profile in it
An operation used in forming sheet Strips of sheet are passed between rolls of definite settings that bend the sheet progressively into structural members of various contours, sometimes called molded sections
A continuous bending operation in which sheet or strip metal is plastically deformed along a linear axis by being passed through a series of roller dies and progressively shaped to the desired contour
