Abstract: A method of bending a contoured metal sheet, the contoured metal sheet having a longitudinal axis extending along the length of the contoured metal sheet comprising: securing a first sheet section of the contoured metal sheet in a securing section between a securing surface of a securing member and an engagement surface of an engagement member; positioning at least part of a second sheet section of the contoured metal sheet in a forming section between a forming member having a pressing surface and a seating member having a seating surface; moving the forming section and the securing section relative to one another to: bend the first sheet section the selected angle relative to the second sheet section over a first bending edge; and feed the second sheet section from between the pressing surface and the seating surface, over a second bending edge, to between a forming surface and a backing surface; and positioning a following section substantially adjacent to the second bending edge to cooperate with the f
