Abstract

A process of producing profiles whose cross-section is variable in the longitudinal direction, characterised by the process stages of cutting a blank 31 with a substantially constant width along a longitudinal direction, deforming the blank 31 by deep-drawing to form an open profile whose cross-section is variable along the longitudinal direction, and cutting the flanges projecting from the open profile.
