Abstract
The material web (1) is acted upon by heated circulating air which permeates with the aid of a fan (7) from a pressure chamber (14) via inlets (6, 6') into the nozzle casings (4, 4'). In order to achieve laminar flow and thus an improved distribution of air, the fan (7) is removed as far as possible from the inlets (6, 6') and preferably suspended beneath the cover-wall (16) of the housing (2). This results in a relatively large and longitudinally extended pressure chamber (14) between the inlets (6, 6') and the pressure side (12) of the fan (7).
