Latest Patents
One of Shirai's latest patents is a method and production line for laminate assembly. This production line features a pressurization measurement apparatus adjacent to a press-working apparatus. A temporary laminate assembly, worked and laminated by a press, is sent to the pressurization measurement apparatus. The laminate assembly is produced by being pressurized and subjected to regular caulking by a hydraulic servo press. The lamination height of the regularly caulked laminate assembly is measured by a linear scale secured at the pressurization measurement apparatus. The main controller inputs data of the measured lamination height and adjusts the number of thin plates to be laminated to match the set lamination height.
