Title (EN) METHOD OF MANUFACTURING INSULATING BOARDS COMPOSED OF INTERCONNECTED ROD-SHAPED MINERAL FIBRE ELEMENTS
(FR) PROCEDE DE FABRICATION DE PANNEAUX ISOLANTS COMPOSES D'ELEMENTS EN FIBRE MINERALE EN FORME DE BAGUETTES ET RECIPROQUEMENT RELIES
Abstract:
(EN) A method of manufacturing insulating board elements composed of interconnected mineral fibre lamellae comprising converting a melt of mineral fibre forming starting material into fibres, supplying a binder to said fibres, causing the fibres to form a fibre web, cutting the fibre web in the longitudinal direction to form lamellae, cutting said lamellae into desired lengths, turning the lamellae 90° about their longitudinal axis and bonding the fibres together to form boards, the lamellae having been subjected to a surface compression followed by a longitudinal compression either before or after the fibre web is cut into lamellae.
(FR) Procédé de fabrication d'éléments de panneau isolant, composés de lamelles de fibres minérales réciproquement reliées, qui consiste à convertir en fibres une masse fondue d'un matériau de départ formant des fibres minérales, à ajouter un produit liant auxdites fibres, à les amener à former une bande continue de fibres, à couper la bande de fibres dans le sens longitudinal pour former des lamelles, à couper lesdites lamelles à leur longueur souhaitée, à les tourner de 90° sur leur axe longitudinal et à lier ensemble les fibres pour former des panneaux, les lamelles ayant été soumises à une compression de surface suivie d'une compression longitudinale soit avant soit après que la bande de fibres a été coupée en lamelles.
