Abstract (en)
[origin: US4934016A] In the device for continuously cleaning a running web of material, the web is continuously moved past an air suction space which extend across the entire width of the web and is in flow connection with an air suction power unit via an air suction channel. The air suction space, which is in flow connection with the air suction channel, can be converging guides, of which a plurality are arranged in tandem in the direction of movement of the web. A plurality of them are also arranged side by side, and these open out into a mutual plane parallel to the web of material. For creating a spread-out holding effect, a plurality of rods, serving as support of the web of material and obliquely towards the middle of the web, and extend in the opening plane of the converging air guides.
