A bushing assembly/support structure arrangement (100) is provided. The arrangement comprises a bushing assembly (110) and a support structure (200). The bushing arrangement includes a bushing main body (120) comprising at least first and second side walls (122a, 122b) and a tip plate (124) extending between the side walls. The tip plate contains a plurality of orifices (124a) through which molten mineral material flows prior to being attenuated into fibers. The bushing assembly further comprises a first support rail (130) coupled to the main body first side wall, and at least one first bracket (140) having an intermediate member (140e) coupled to the main body first side wall. The support structure comprises a bushing frame (210), and at least one first support strap (220). The support strap has a first end (220a) fixedly coupled to the bushing frame and second end (220b) extending toward a first location on the support rail adjacent the first bracket for supporting the bushing assembly.

L'invention concerne un dispositif (100) constitué d'un ensemble filière (110) et d'une structure de support (200). L'ensemble filière (110) comporte un corps principal de filière (120) comprenant au moins une première et une seconde paroi latérale (122a, 122b) et une plaque d'extrémité (124) disposée entre les parois latérales. La plaque d'extrémité (124) est traversée par une pluralité d'orifices (124a) à travers lesquels s'écoule la matière minérale en fusion avant d'être réduite en fibres. L'ensemble filière (110) comporte également un premier rail d'appui (130) relié à la première paroi (122a) du corps principal (120) et au moins un premier organe de fixation (140) comprenant un élément intermédiaire (140e) relié à la première paroi (122a) du corps principal (120). La structure de support (200) comporte un cadre pour filière (210) et au moins une première patte de support (220). Cette patte de support (220) possède une première extrémité (220a) solidement fixée sur le cadre pour filière (210) et une seconde extrémité (220b) qui s'étend vers un premier emplacement situé sur le rail d'appui (130), à proximité du premier organe de fixation (140), destinée à servir de support à l'ensemble filière (110).
