Abstract
Apparatus for packaging mineral fiber insulation material includes a compression member to gradually compress the material, where the compression member contains a plurality of depressions, the downstream edge of the depressions being sloped to gradually blend with the plane of the compression surface, and the upstream edge of the depressions forming an abrupt drop from the plane of the compression surface, thereby defining an aperture at the upstream edge of the depressions for the escape of air during compression of the material, where the upstream edge is adapted to support the insulation material during the venting of the compressed air.
