Title
(EN) A DEVICE FOR MAKING POLYMER FIBRE FOR A SYSTEM OF THE SPUNBOND AND/OR MELT-BLOWN TYPE
(FR) DISPOSITIF DE FABRICATION DE FIBRE DE POLYMÈRE POUR UN SYSTÈME DE TYPE FILÉ-LIÉ ET/OU FONDU-SOUFFLÉ
Abstract
(EN)
A device (1) is provided for making polymer fibre for a system of the spunbond and/or melt-blown type, comprising a distributor (3) including at least one distribution pipe (30) adapted to distribute the polymer fluid, filtering means (4) arranged upstream of the distribution pipe (30) so as to filter the polymer fluid, wherein the filtering means (4) include a porous element (40) defining a plurality of non-rectilinear passage channels of varying sizes.
(FR)
L'invention concerne un dispositif (1) pour fabriquer une fibre de polymère pour un système du type filé-lié et/ou fondu-soufflé, comprenant un distributeur (3) comprenant au moins un tuyau de distribution (30) conçu pour distribuer le fluide de polymère, un moyen de filtrage (4) disposé en amont du tuyau de distribution (30) de manière à filtrer le fluide de polymère, le moyen de filtrage (4) comprenant un élément poreux (40) définissant une pluralité de canaux de passage non rectilignes de tailles variables.
