Title
(EN) APPARATUS AND METHOD FOR FIBER BATT ENCAPSULATION
(FR) APPAREIL ET PROCEDE POUR ENCAPSULATION DE NAPPAGE FIBREUX
Abstract
(EN)
Disclosed is an apparatus and a method for at least partially encapsulating a fiber batt (100) or other substrate by applying a polymer fiber layer to one or more surfaces of the fiber batt or substrate by melt-blowing. The melt-blowing assemblies (110, 118) are arranged and configured to extrude both a polymer melt (112) and a hot gas stream (114) whereby the hot gas stream attenuates the polymer melt to form polymer melt fibers and to direct the polymer melt fibers toward a surface to be coated. The melt-blowing assemblies are further arranged and configured to apply a cooling fluid (120) to the polymer melt to quench a surface portion of the polymer melt fibers before the polymer melt contacts a surface of the fiber batt. A combination of melt-blowing assemblies may be provided in either fixed or moveable configurations for coating one or more sides of the fiber batt.

Un appareil et un procédé d'encapsulation au moins partielle d'un nappage fibreux (100) ou d'un autre substrat par application d'une couche fibreuse polymère sur une ou plusieurs surfaces de nappage fibreux ou du substrat par procédé de fusion-soufflage. Les ensembles de fusion-soufflage (110, 118) sont disposés et configurés de manière à extruder à la fois le polymère fondu (112) et un courant gazeux chaud (114), le courant atténuant le polymère fondu afin d'obtenir des fibres de polymère fondu et de diriger les fibres vers une surface à recouvrir. Les ensembles de fusion-soufflage sont disposés et configurés de manière à appliquer un fluide de refroidissement (120) sur le polymère fondu afin de faire subir à la partie superficielle des fibres de polymère fondu un bain d'extinction avant que le polymère fondu entre en contact avec la surface du nappage fibreux. Une combinaison d'ensembles de fusion-soufflage peut adopter les configurations fixes ou mobiles afin de revêtir un ou plusieurs côtés du nappage fibreux.
