The present invention relates to a device for manufacturing comical poles or comical pole members by roll forming sheet metal, whereby said device (1) comprises a conveyor path (5) along which sheet metal is transported, and a plurality of groups (10) of forming rolls (11, 12) positioned in succession along the conveyor path (5). In order to facilitate the roll forming and eliminate the risk of bending the sheet metal during the roll forming, the forming rolls (11, 12) in at least on of the groups (10) thereof are mounted on frame members (13) which are pivotable about vertical axes (26) such that the forming rolls (11, 12) can be set to run at such angles ( alpha or beta ) relative to the centre line (6) of the conveyor path (5) that are dependent on the comical form of the finished pole or pole member or portions thereof. |
