(EN) METHOD FOR PRODUCING A FILTER ELEMENT
(FR) PROCEDE POUR PRODUIRE UN ELEMENT FILTRANT
Abstract
(DE)
Es wird ein Verfahren zur Herstellung eines Filterelements beschrieben, welches aus einem Faltenpack eines Filtermediums besteht. Bei diesem Verfahren werden wenigstens zwei Leimraupen entlang zweier Seiten auf das Filterelement angebracht und dies ist zu einer kompakten Einheit geformt. Zur Abdichtung wenigstens zweier Seiten werden ein oder zwei Dichtstreifen mit einem Schmelzkleber angebracht, wobei der Dichtstreifen ein vorkonfektioniertes V-förmiges Profil aufweist.
(EN)
The invention relates to a method for producing a filter element comprising a folded pack of a filter medium. According to this method, at least two glue beads are applied along two sides of the filter element and the latter is moulded into a compact unit. One or two sealing strips are applied with a hot-melt adhesive for sealing at least two sides, said sealing strips having a pre-made V-shaped profile.
(FR)
L'invention concerne un procédé pour produire un élément filtrant constitué d'un ensemble plissé, réalisé à partir d'un matériau filtrant. Selon ce procédé, au moins deux cordons de colle sont appliqués longitudinalement sur deux côtés de l'élément filtrant pour permettre l'obtention d'une unité compacte. Afin d'étanchéifier au moins deux côtés, une ou deux bandes d'étanchéité sont appliquées avec un adhésif thermofusible, lesdites bandes présentant un profil en V formé au préalable.
