Abstract (en)
The procedure for transporting a strip of a non-woven material (WE) on a conveyor belt (100) that has at least one section (100a) where it rises at an angle and/or varies in speed differs by applying an electrostatic charge to the strip and/or conveyor belt in the aforementioned section, with the charge covering at least the full width of the non-woven material. The electrostatic charge is supplied by an ioniser (15) with at least one ionising bar located above and close to the conveyor belt's rising and/or variable speed section.
Abstract (fr)
On transporte une bande de non-tissé (WE) au moyen d'une bande de transport (100) comportant au moins une portion de transport (100a) qui est ascendante et/ou qui subit des changements de vitesse. En cours de transport, on charge électrostatiquement la bande de non-tissé (WE) et/ou la bande de transport (100), en sorte de faire adhérer la bande de non-tissé à la surface de la bande de transport dans ladite portion de transport (100a) ascendante et/ou à vitesse variable. Application : transport d'une bande de non-tissé (WE) à l'entrée d'un étaleur-nappeur (1).
