(FR) ASSEMBLAGE DE FILAMENTS METALLIQUES EN NAPPES POUR LA PRODUCTION DE CORPS EN NIDS D'ABEILLES
Abstract
(DE) Verfahren zur Herstellung eines Vlieses (1) umfassend metallische Drahtfilamente (2) mit zumindest folgenden Schritten: a) Bilden einer Lage (3) mit Drahtfilamenten (2); b) Erzeugen von ersten stoffschlüssigen Verbindungen (4) zwischen zumindest einem Teil der metallischen Drahtfilamente (2) mit einem ersten Fügeverfahren; c) Erzeugen von zweiten stoffschlüssigen Verbindungen (5) zwischen metallischen Drahtfilamenten (2) mit einem zweiten Fügeverfahren. Weiter werden entsprechende Vliese und vorteilhafte Einsatzmöglichkeiten, beispielsweise bei der Abgasbehandlung von Kraftfahrzeugen, beschrieben.
(EN) The invention relates to a method for producing a nonwoven structure (1) comprising metal wire filaments (2) by carrying out the following steps: a) producing a layer (3) comprising wire filaments (2); establishing first integral joints (4) between at least a part of the metal wire filaments (2) using a first joining method; c) establishing second integral joints (5) between metal wire filaments (2) using a second joining method. The invention also relates to corresponding nonwoven structures and to possible uses thereof, for example in the exhaust gas treatment of motor vehicles.
(FR) L'invention concerne un procédé pour la production d'une nappe (1) comprenant des filaments métalliques (2). Le procédé selon l'invention comprend au moins les étapes suivantes : a) formation d'une couche (3) avec des filaments métalliques (2) ; b) création de premiers assemblages (4) par liaison de matière entre au moins une partie des filaments métalliques (2) au moyen d'un premier procédé d'assemblage ; c) création de deuxièmes assemblages (5) par liaison de matière entre des filaments métalliques (2) au moyen d'un deuxième procédé d'assemblage. L'invention concerne également des nappes correspondantes et leurs possibilités d'utilisation avantageuses, notamment pour le traitement des gaz d'échappement de véhicules automobiles.
