PROCESS FOR THE PRODUCTION OF ARTIFICIAL GLASS FIBER PRODUCT AND THE DEVICE FOR IMPLEMENTATION THEREOF |
摘要 |
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 (4). 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. |
