  • Leaf coater and method for producing leaf type coated substrates
    Patent number: 6783803
    Abstract: A leaf coater, in which a constant quantity of a coating solution is supplied intermittently from a coating solution supply source through a predetermined coating solution quantity intermittent supply means and a coating solution applying means to a blank substrate, for coating blank substrates one by one with the coating solution, characterized in that a coating solution filtration means is provided in the coating solution flow pipeline from said coating solution supply source to the coating solution applying means, and the Young's modulus of the filter medium in the coating solution filtration means is not less than 200 MPa, while the pore size of the filter medium is in the range of 0.05 &mgr;m to 100 &mgr;m; and a method for producing coated substrates using said leaf coater.
    Type: Grant
