Abstract: A system for packaging a number of substantially cylindrical packages of generally elastic insulation material. The packages have open ends but are surrounded by a substantially airtight foil layer. The packages are placed close to one another and their ends are temporarily, essentially airtightly closed. The packages are pressed closely against each other by holders. The packages are then connected to a vacuum through a perforated plate to reduce their volume. The reduced volume packages are then wrapped within a tight foil enclosure after the holders are removed but before the vacuum is disconnected. The system not only reduces the volume of the individual packages but also eliminates interspaces therebetween.
