Abstract (en)
[origin: WO2020148033A1] The invention relates to a device for treating a material web (1), comprising a treatment chamber (2), means for transporting the material web (1) through the treatment chamber (2), said treatment chamber (2) having an inlet slot (3) and an outlet slot (4) for the material web (1), and means (7) for largely sealing the inlet slot (3) and/or the outlet slot (4). The device should be capable of being largely sealed in the region of the inlet slot (3) and/or the outlet slot (4) during operation regardless of the shape of the material web (1). This is achieved in that the sealing means (7) comprise a plurality of segments (8) with respective free ends (8.3) which have a variably adjustable height.
