Abstract: The invention generally relates to the packaging of compressible material into compressed rolls and in particular, to a method and apparatus for packaging fibreglass insulation and similarly compressible materials, into highly compressed, consistently uniform, rolls. Such rolls are easier and less expensive to handle, store and ship. The main design of the invention is for a roll-up machine which has three continuous belts defining a circular cavity and establishing generally circumferential contact with the compressible material so that the compressible material is under compressive pressure as it is being rolled; means for putting the three continuous belts under tension; means for driving the three continuous belts; and means for feeding the compressible material into the circular cavity.
