摘要

The shaped sheet producing process involves using a deforming roll (1) on the edge of the sheet (2) to produce a flange pointing away from the sheet plane of less thickness than the initial thickness of the workpiece (u) from the sheet edge. A translatory movement takes place between the sheet and the deforming roll.
