Abstract
An apparatus for coating a paper web in which a coating mix is applied onto a paper web using an applicator unit which forms a linear mechanical force on the web against a first backing surface situated on the back side of the web. The coating mix applied onto the web is doctored using a doctor unit acting against a second backing surface. The speed of at least one of the backing surfaces is independently controlled relative to the speed of the first backing surface and the web speed in order to attain control of the tensile stress of the web.
