2 Process Idea

The basic idea of the flexible rolling process is a modification of a conventional cold rolling process. During the rolling, the roll gap is adjusted in order to achieve the desired thickness profile in rolling direction (see Fig. 1). Thereby, a material flow in rolling direction is achieved and smooth thickness reductions in longitudinal direction can be produced. These homogeneous thickness reductions outreach comparable tailored blanks produced by joining operations as no welding seams are necessary. Therefore, no material weakening occurs as the flexible rolled sheet still shows a persistent microstructure without a welding seam throughout the whole sheet [6].
