摘要 |
An apparatus for coating a pasty mixture on a substrate and the method for coating the pasty mixture is disclosed. The weight of the paste (21) per area is measured continuously without contact by irradiating the belt-shaped paste-coated punched metal electrode (41) with beta ray (51), during running of the electrode (41) on a production line. Then trapping dosage of the beta ray radiation transmitted through the electrode (41) by an ionization chamber (4b,50) is followed by processing the measured value in a micro-processor unit (6) on the basis of comparing with a previously determined reference value. By means of the output signal from the processor (6), the gap of slit (24) between the blades (23a and 23b) is feed-back-controlled, so as to control thickness, hence weight per unit area of the pasty mixture uniform. <IMAGE> |
