摘要 |
A device for producing a mineral wool nonwoven fabric, comprising a drop shaft and fibrillation devices in addition to a conveyor device for the conveyance of mineral wool nonwoven fabric. A device is also provided to separate the strip of insulating material into a first section and a second section in a longitudinal direction. A conveyor device directs the first section in such a way that it is placed on the second section. The device enables a mineral fiber product to be created with a density distribution that is such that the upper area and the lower area have a higher density than the area located inbetween. |
