Heat-bonding textile materials and stiffening materials - using weighing balance altering voltage of heated capacitor plates

摘要

The panels of textile materials which are to be stuck to corresponding panels of stiffening material pass through a hydraulically driven fixing press which has a fixed pressing table contg. one capacitor plate and a movable pressing plate contg. the other capacitor plate. The two condenser plates each have ducts which are provided with several bores opening onto the facing work surfaces and which are connected to the suction side of a fan. Theses capacitor plates are heated to provide the necessary heat action or fusion and the mass of stacked material to be treated is weighed. The result is fed into a known capacity regulator system to control the processing temp. by regulating the HF energy. The weighing result can directly alter the comparison voltage e.g. through a potentiometer which is driven by the indicator shaft of a balance.
