Abstract
Hot foil stamping machine stamping a foil onto a substrate, which improves stamping quality under changing conditions, includes a control unit for controlling the temperature of the stamping interface surface to a predefined desired temperature. The control unit receives at least an actual temperature of the heating plate from the at least one temperature sensor and provides a manipulated variable to the at least one heating device. Further, the stamping machine includes a state observer for estimating an actual temperature of the stamping interface surface of the at least one stamping plate based on a physics-based analytical model of the heat transfer between the heating plate and the stamping plate. The control unit also includes a feedback controller for calculating the manipulated variable for a heating device based on the predefined desired temperature and the estimated actual temperature of the stamping interface surface provided by the state observer.
