Abstract
An apparatus for making a substantially air-tight foil package for mineral wool that includes a mechanical compressing device for compressing the mineral wool in a first direction to bring about a dimensional reduction thereof. A wrapping device encloses the mineral wool with a web of a substantially air-tight foil. An evacuating station is arranged downstream of the compressing device and it includes an evacuating device for evacuating air from the mineral wool compressed by the compressing device and enclosed by the foil. The evacuating station includes opposed surfaces for maintaining the dimensional reduction during transfer to the evacuating means of the foil enclosed mineral wool compressed by the compressing device. The opposed surfaces maintain the dimensional reduction during evacuation by the evacuating device.
