| 摘要 |
<p>The invention relates to a method and a device for coating a continuous strip of material (B), specially paper or cardboard, with a liquid or paste-like application medium. Said pre-dosed application medium is applied (at 240) directly or indirectly to the material strip (B), whereupon final dosing according to the desired weight of application and/or equalization (at 255) is carried out. Final dosing and/or equalization occurs only after a minimum time period (tmin) starting from pre-dosing in order to guarantee the formation of a coating of immobilized solids on the material surface in the application medium. Additionally or alternately, the immobilization of solids can be actively accelerated (by 278, 280, 282, 284). Another aspect of the invention provides for final dosing only after a maximum time period (tmax).</p> |
