Abstract
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), 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 feedback-controlled, so as to control thickness, hence weight per unit area of the pasty mixture uniform.
