Abstract
The invention concerns a pressing arrangement for a moving web. The arrangement comprises a cylindrical roll forming a press zone with a glide-belt which is at least partially and slidingly supported by a shoe having a contour of alterable convexity along the press zone surface so as to alter the length of the press zone. Supply mechanisms are provided to supply lubricant for a lubricating film between the glide belt and the shoe. The shoe can be supported by a counter roll situated on the opposite side of the shoe relative the press roll and have a concave surface mating the counter roll thus enabling adjustment of the shoe around the centerline of the counter roll. In an alternative arrangement a desired press zone length could be obtained by installing a removable insert having a proper contour in the press zone area of the shoe.
