An apparatus (10) and process are provided for filling a passage (62) betwee n first and second elements (110, 50) with fiber insulation material (120). Th e apparatus (10) comprises a support (20), an exhaust box (30) rotatably mount ed on the support (20) and having an inner cavity (33) and a fixture (36), a device (40) effecting rotation of the exhaust box (30), and first and second elements (110, 50). The first element (110) has an outer surface and the second element (50) has an inner surface. The second element (50) is positioned relative to the first element (110) such that the first and secon d elements (110, 50) define therebetween the passage (62) which is filled with fiber insulation material (120). At least one of the first and second elemen ts (110, 50) is perforated. The apparatus (10) further includes at least one filling nozzle (60) adapted to supply fiber insulation material (120) to the passage (62) and a vacuum source (130) adapted to draw a partial vacuum in t he exhaust box (30) inner cavity (33) while the fiber insulation material (120) is supplied to the passage (62). The partial vacuum causes air to be pulled through the at least one perforated element thus causing the fiber insulatio n material (120) to be densely packed within the passage (62). |
