The invention relates to a method for regulating the vacuum supply of calibration tools (4a, 4b; 5a, 5b), said tools comprising at least one dry calibration tool (4a, 4b) and at least one calibration bath (5a, 5b). According to said method, at least one vacuum pump (17a, 17b, 17c, 17d) is brought into contact with a calibration tool (4a, 4b; 5a, 5b), in order to extract air from the calibration tool (4a, 4b; 5a, 5b), the pressure in said tool (4a, 4b; 5a, 5b) being regulated to a target value by means of a contro l valve (13, 15). The aim of the invention is to reduce the energy consumption and increase the quality of the profile produced. To achieve this, several vacuum pumps (17a, 17b, 17c, 17d) extract air from a common pressurised container (16), the air is extracted from at least one dry calibration tool (4a, 4b) by means of a first control valve (13) in said common pressurised container (16) and in addition the air is extracted from at least one calibration bath (5a, 5b) by means of a second control valve (15) in the common pressurised container (16). The invention also relates to a device fo r carrying out said method.
