A dryer section for drying a web of fibrous material is provided, which has at least one drying unit for reducing the moisture content of the web by means of convection drying. The drying unit has at least one nozzle for applying a drying fluid to the web, at least one discharge device for the moist air produced during convection drying, and transport means for moving the web relative to the drying unit. The drying unit has at least one ultrasonic generator, which is arranged, for excitating vibrations in the drying fluid, in the region of the nozzle in such a manner that the reduction of the moisture content by ultrasound can be supported over the entire width of the web.

The invention relates to a method for producing thermosensitive recording material, comprising a carrier substrate and a thermal reaction layer containing a color former and a color developer. According to the invention, an application suspension, containing the starting materials of the thermal reaction layer, is applied to the carrier substrate and the carrier substrate is subsequently dried with the applied application suspension. Then the dried carrier substrate with the applied thermal reaction layer is guided through a smoothing mechanism in order to be smoothed, wherein the dried carrier substrate with the applied thermal reaction layer is pressed extensively against a roller by means of a predetermined contact pressure. The invention also relates to a recording material which is produced according to the inventive method.
