APPARATUS AND METHOD FOR BENDING CONTOURED METAL SHEETING ABOUT A FOLD LINE
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 forming surface to engage and compress a portion of the second sheet section of the contoured metal sheet therebetween when the relative movement between the securing section and the forming section moves the backing surface to a position remote from the forming surface of the forming member.

B21D 7/03 - Apparatus with means to keep the profile in shape
A method of bending a contoured metal sheet about a selected fold line. The contoured metal sheet has a longitudinal axis extending along the length of the sheet, and a contoured profile that extends perpendicular to the longitudinal axis of the sheet. The method comprises: engaging a first sheet section of the contoured metal sheet with a forming member which comprises a forming surface having a contour shaped with a substantially symmetrical mirror profile to the contoured profile of the first sheet section. The engagement of the forming member with the first sheet section bends the first sheet section of the metal sheet about a fold line relative to a second sheet section of the metal sheet to position the first sheet section at a selected angle relative to the second sheet section about the fold line, and also transforms the contoured profile of the first sheet section into a new contoured profile comprising a symmetrical mirror of the contoured profile of the second sheet section about the fold line.
