  • Patent number: 8919008
    Abstract: The invention relates to a Yankee dryer (1) made of steel with a cylindrical steel shell (2) that is closed off at each end by a cylinder end cover (3, 4). According to the invention the Yankee dryer (1) has a one-piece central shaft (7) with a first and a second connecting flange (8, 9) to join the central shaft (7) to the end covers (3, 4), where the diameter of the first connecting flange (8) is smaller than the diameter of the opening (6) in the second end cover (4) so that the central shaft (7) can be pushed through this opening (6) into the Yankee cylinder (1). The invention also refers to a manufacturing process for a Yankee dryer (1).

  • Patent number: 8302898
    Abstract: The invention relates to a device for continuous reeling of a pulp web (1), particularly a paper web, for example tissue, where the pulp web (1) is carried over a reel drum (2) that is supported on rocker arms (4) and is then wound onto a winding unit (5), and the pressing force in the nip (24) is measured between paper roll (16) and reel drum (4) with the aid of a load-sensing device (7), where the rocker arm (4) can be preloaded against the load-sensing device (7), where the rocker arm (4) can be preloaded against the load-sensing device (7) by means of a preloading element (8). It is mainly characterized by the preloading force for preloading the rocker arm (4) against the load-sensing device (7) being adjustable by means of the preloading element (8).
