Abstract
A material web drier containing a device for controlling the gas flow of a drying medium as a function of the actual state of the wet material web which is to be dried, comprising nozzle casings or surfaces containing blow-out or discharge openings arranged in cooperating relationship with respect to the material web. The discharge openings are directed towards the material web and serve for blowing-out the drying medium onto the web. For the purpose of dosing the gas flow or stream effluxing at the nozzle casings or surfaces, there are provided opening and closing elements which free the discharge openings or partially or completely close the same, as desired, whereby it is possible to vary the impingement of the material web by the drying medium selectively at discrete locations or regions thereof, both in the lengthwise and transverse directions of such material web.
