摘要：The invention relates to a method of forming a sheet-like workpiece (1) into a lengthwise irregular shape in a roll-forming machine (2) having several sequentially arranged stations (3A-G) with upper and lower forming tools (5, 6). According to the invention, this is specifically achieved by intentionally interrupting the roll forming of the workpiece during its passage through the roll-forming machine. More specifically, the forming is interrupted before the entire workpiece (1) has passed all forming stations (3-A-G). This enables forming products having a genrally tapered shape in the forming direction, in one and the same work step and at a comparatively low cost is.
