Abstract: A counter roll (26) is positioned to engage a paper or board web (24) in a paper or board making machine along a contact line. A pressure-sensitive EMFi film (28) is disposed on the counter roll to measure the pressure profile of the web along the contact line. A coating apparatus (22) applies a coating to the web passing over the counter roll (26), and a pressure profile of the applied coating is measured by the pressure-sensitive film (28) on the counter roll (26). The pressure-sensitive film (28) may also be disposed to detect details of coating application in a curtain coater (30). Moreover, the film may be driven to provide adjustable vibration for cleaning the coater, or conditioning or controlling the coating flow.

Abstract: The present invention relates to a reeling apparatus (1) for fiber web by which fiber web may be wound to successive reels (4). The reeling apparatus has cutting devices (6) for cutting the web during a reel change, the cutting device being provided with at least one cutting head (6.2) disposed movable in a direction essentially transverse to the web direction to cut the web. A contactless web supporting arrangement (7) is been provided in operational connection with the cutting device to maintain the running of the web stable in a controlled manner during the cutting.
