Patent

CA 2618825

A non-woven product having a core layer (32) containing dense particulate additive between adjacent layers (33) which are substantially free of additive is made by fiberising a mineral melt on a spinner (1) comprising at least one fiberising rotor (2, 3, 4) mounted for rotation about a substantially horizontal axis, and the resultant fibres are collected in air streams (5) as a cloud of fibres which travels towards a travelling collector (11) on which a web (14) is formed and carried out of the spinning chamber (9). Dense particles such as magnesium hydroxide are ejected from a suitable ejector (15) on to a baffle (16) by which they are deflected across the width of the chamber and lengthwise over the length of a intermediate collecting zone (B) to form the core layer (32) while the initial and final collecting zone (A and C) are substantially free of the dense particulate additive.

L'invention concerne un produit non tissé possédant une couche d'âme (32) contenant un additif particulaire dense entre des couches adjacentes (33) qui n'ont sensiblement aucun additif. Selon l'invention, le produit est fabriqué en défibrant une masse minérale fondue sur un métier à filer (1) qui comprend au moins un rotor de défibrage (2, 3, 4) monté de façon à tourner sur un axe sensiblement horizontal, les fibres résultantes étant recueillies dans des jets d'air (5) sous forme de nuage de fibres qui se déplace vers un collecteur mobile (11) sur lequel une bande (14) est formée et transportée hors du compartiment de filage (9). Selon l'invention, des particules denses, telles que de l'hydroxyde de magnésium, sont éjectées d'un éjecteur approprié (15) sur une cloison (16) qui les fait dévier sur la largeur du compartiment et, dans le sens de la longueur, sur la longueur d'une zone collectrice intermédiaire (B) pour former la couche d'âme (32) alors que les zones collectrices initiale et finale (A et C) sont sensiblement exemples de l~additif particulaire dense.
