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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hot foil stamping machine","description":"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","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11981118","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
