摘要： A method and apparatus for manufacturing calendered paper in which the paper is calendered after drying. The paper is dried (D) sown to a moisture lower that the target moisture of calendering. The paper is run via wetting (1) to calendering, wherein at least one of the surface layer of the paper is wetted in the wetting in such that the moistening water is absorbed in the surface layer of the paper while at lest the central part remains substantially dry. From the paper wetted at least on one of its sides, gradient paper is manufactured by means of gradient calendering by restricting the paper-molding effect of the calender to the wetted surface layer in such a way that at least the paper is elastically restored substantially in its original state, whereafter the obtained gradient paper is reeled.

The drying fabric is adapted to support and transport the paper web about a portion of the circumference of the cylinder of each dryer. The fabric support members preferably include a first fabric support member located at an upstream end of the apparatus for directing the wet web and the fabric onto the cylinder of the upstream through-air dryer, and a second fabric support member located at a downstream end of the apparatus for directing the web and the fabric from the cylinder of the downstream through-air dryer. The hood further interacts with at least the first and the second fabric support members and covers a portion of each cylinder about which the fabric and the wet web are wrapped. Further, the plenum cooperates with the hood and at least the first and the second fabric support members to substantially seal the enclosure containing each cylinder. Preferably, and more specifically, the plenum forms seals with both the first and the second fabric support members with at least one of the seals being formed by the plenum sealingly engaging the fabric wrapped about the corresponding fabric support member.
