Sheet-metal elements made of flexibly rolled material strip

摘要

The invention relates to sheet-metal elements made of flexibly rolled material strip having different thicknesses in the longitudinal direction of the strip. A solution according to the invention consists in a sheet-metal element reshaped about the longitudinal direction of the strip or reshaped transverse to the longitudinal direction of the strip from a flexibly rolled material strip having different thicknesses in the longitudinal direction of the strip to form a tube or profile body having an out-of-round cross-section and variable wall thickness over the length or over the circumference.
