Abstract: In metering viscous paste from a paste pot onto a carrier tape using a scraper, uniform coating thickness is obtained by causing the scraper to oscillate relative to the paste in a plane parallel to the carrier tape, with a speed which equals at least the tear velocity between scraper and paste. The scraper projects into the paste to a depth at which the paste does not yet firmly adhere to the carrier, and holds back the excess paste free of torn-off portions even at high tape speeds. An important application of this method is in the production of raw sinter tape in connection with the manufacture of electrodes for galvanic elements.

Abstract: The sealing ring which encircles the pole bolt protruding through a cell cover is compressed between the cover and the head of the pole bolt. The degree of compression is limited by a non-elastic spacer ring encircling the sealing ring.
