    摘要: An apparatus for transferring a wet paper web from a press nip to a drying cylinder (52) of a papermaking machine, and for structuring the web, comprises an impermeable transfer belt (35) having a web-contacting surface, the wet paper web passing through the press nip enclosed between a press felt (33) and the transfer belt, and a permeable structuring fabric (37) for transfer of the web onto the drying cylinder, the structuring fabric having a structured surface and being arranged in a loop within which a suction transfer device (38) is disposed, said suction transfer device having a suction zone (41). According to the invention the web-contacting surface of the belt has a non-uniform distribution of microscopic-scale depressions, and that the suction zone includes a transfer point (40) spaced a distance D from the press nip along which the belt runs, the belt being arranged to bring the web into contact with the structuring fabric in the suction zone for a length L, such that suction is exerted on the paper web to transfer the paper web from the belt onto the structuring fabric. at the transfer point.

    摘要: An apparatus and method for turning-up a web is disclosed that results in greater efficiency. The method has been found to work especially well when the web is a bulky tissue web, but is also suitable for other web materials. The apparatus includes a reel spool having a cylindrical surface, the cylindrical surface includes at least one axial line of adhesive and a plurality of apertures operatively connected to a source of vacuum.
