The production line according to the present invention is provided with a pressurization measurement apparatus adjacent to a press-working apparatus, a temporary laminate assembly worked and laminated by a press in the press-working apparatus is sent to the pressurization measurement apparatus, and a laminate assembly is produced by being pressurized and being subjected to regular caulking by a hydraulic servo press of the pressurization measurement apparatus. At this time, the lamination height of a regularly caulked laminate assembly is measured by a linear scale secured at the pressurization measurement apparatus. The main controller of a control apparatus inputs data of the measured lamination height, and adds and subtracts the set number of thin plates to be laminated of a laminate assembly by controlling the laminating means of the press-working apparatus so that the measurement lamination height is matched to the set lamination height using the measured lamination height, the preset lamination height, the height dimension tolerance, and the tolerance for judging the number of thin plates.
