Abstract (en)

[origin: WO2018147773A1] During the roll-forming of a plate bar section (11) to a profile (12, 13) with variable width and upright sides (22, 23) with (Figure 1) or without (Figure 2) flanges (24, 25), the upright sides (22, 23) are clamped in one of the last three forming stations (Figure 12). This can yield a product with a plane bottom so that the product is not bent up (Figure 8) or down (Figure 10), which happens without the above-cited clamping (Figure 13) of the upright sides (22, 23).
