Abstract

Eine Trockenpartie 10 einer Maschine zur Herstellung einer Materialbahn 12 wie insbesondere einer Papier- oder Kartonbahn umfaßt wenigstens eine Trockengruppe 14 mit zumindest einem Trockenzylinder 16 und wenigstens eine Bahnleiteinrichtung 18, 20, um die die Materialbahn 12 mäanderförmig herumgeführt ist. In dieser Trockenpartie 10 wird der sich in der Materialbahn 12 quer zur Bahnlaufrichtung ergebende Schrumpfverlauf dadurch eingestellt oder kontrolliert, daß wenigstens ein, vorzugsweise mehrere Bereiche geschaffen werden, in denen jeweils eine zumindest im wesentlichen freie, ungehinderte Schrumpfung der Materialbahn 12 möglich ist.

A drying section 10 of a machine for producing a material web 12, such as in particular a paper or cardboard web, comprises at least one drying group 14 with at least one drying cylinder 16 and at least one web guiding device 18, 20, around which the material web 12 is guided in a meandering manner. In this dryer section 10, the shrinkage course which results in the material web 12 transversely to the web running direction is adjusted or controlled by creating at least one, preferably several areas, in each of which an at least substantially free, unimpeded shrinkage of the material web 12 is possible.
