Abstract: The invention relates to a Yankee drying hood arrangement (1) which is shaped to be fitted over a Yankee drying cylinder (2) such that the drying hood arrangement (1) can cover a part (4) of the circular cylindrical surface (3) of a Yankee drying cylinder (2). The Yankee drying hood arrangement (1) comprises a plurality of nozzle boxes (5) distributed equidistantly around an imaginary axis (X) such that, when the Yankee drying hood arrangement (1) is fitted over a Yankee drying cylinder (2), the nozzle boxes (5) are spaced from the circular cylindrical surface (3) of the Yankee drying cylinder (2) but form a curved structure (6) that follows the outer contour of the circular cylindrical surface (3) of the Yankee drying cylinder (2).

Abstract: The invention relates to a process and a machine for making a tissue paper web (W) in which the tissue paper web W is passed through an extended nip N formed between an extended nip unit (2) and a Yankee drying cylinder (1) and in which the tissue paper web W is carried on a felt (3) through the extended nip N in such a way that, in the extended nip N, the tissue paper web W contacts the outer surface (4) of the Yankee drying cylinder (1). The web W and the felt (3) are led over a suction roll (5) prior to the extended nip N in such a way that the felt (3) contacts the suction roll (5) and the tissue paper web W is separated from the suction roll (5) by the felt (3). The suction roll (5) has a suction zone (6) over which the felt (3) and the tissue paper web W pass together, and a first hood (7) is arranged opposite the suction roll (5) and partially surrounds the suction roll (5).
