An apparatus and process are provided for filling a passage between first and second elements with fiber insulation material. The apparatus comprises a support, an exhaust box rotatably mounted on the support and having an inner cavity and a fixture, a device effecting rotation of the exhaust box, and first and second elements. The first element has an outer surface and the second element has an inner surface. The second element is positioned relative to the first element such that the first and second elements define therebetween the passage which is filled with fiber insulation material. At least one of the first and second elements is perforated. The apparatus further includes at least one filling nozzle adapted to supply fiber insulation material to the passage and a vacuum source adapted to draw a partial vacuum in the exhaust box inner cavity while the fiber insulation material is supplied to the passage. The partial vacuum causes air to be pulled through the at least one perforated element thus causing the fiber insulation material to be densely packed within the passage.

[ What is claimed is:] [1.]1. An insulation packing process comprising the steps of:providing a first element having an outer surface and a second element having an inner surface, at least one of said first and second elements being perforated;providing said first and second elements on a fixture, said second element being located so as to be positioned relative to said first element such that said first element outer surface and said second element inner surface define a passage between said first and said second elements for receiving fiber insulation material, said fixture forming part of an exhaust box and said exhaust box having an inner cavity which communicates with a vacuum source;supplying fiber insulation material to said passage such that said material is packed into said passage;rotating said fixture and said first and second elements during said supplying step; anddrawing a partial vacuum in said exhaust box via said vacuum source while the fiber insulation material is being supplied to said passage, said partial vacuum causing air to be pulled through said at least one perforated element so as to cause said fiber insulation material to be densely packed within said passage.
