Abstract
A counter roll () is positioned to engage a paper or board web () in a paper or board making machine along a contact line. A pressure-sensitive EMFi film () is disposed on the counter roll to measure the pressure profile of the web along the contact line. A coating apparatus () applies a coating to the web passing over the counter roll (), and a pressure profile of the applied coating is measured by the pressure-sensitive film () on the counter roll (). The pressure-sensitive film () may also be disposed to detect details of coating application in a curtain coater (). Moreover, the film may be driven to provide adjustable vibration for cleaning the coater, or conditioning or controlling the coating flow.
