Abstract

In a drying section of a machine for producing a material web such as, in particular, a paper or cardboard web, a pick-up suction roll, in particular a larger pick-up suction roll, is provided between the last pressing nip of a pressing section and a subsequent impingement drying unit, which suction roll removes the material web from a pressing felt guided through the pressing nip or from a transfer belt and transfers it to the impingement drying unit.
