Abstract (en)

[origin: DE19643934A1] The invention relates to a method and a device to produce structured sheet metal. According to the inventive method, a strip of sheet metal (6) initially undergoes a structuring operation wherein a structure (8) is formed, whose structural height (H) is greater than a theoretical structural height (SH), followed by a calibration operation in a calibration unit (9). The structure (8) is guided through two rollers (10, 11) of the calibration unit (9) whereby the height of the structure once it has passed through the calibration unit (9) corresponds to the theoretical structural height (SH).
