Yankee dryer for drying a pulp web

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