Abstract
A conveyor displaces a succession of identical screens along a closed annular path having a generally horizontal upper stretch and a lower return stretch spaced below the upper stretch. Particle mats are formed on the screens on the upper stretch. A press along the upper stretch downstream of the mat-former compresses the mats into rigid panels. A screen changer includes a unit for removing a bad screen from the conveyor and a unit for feeding a fresh screen to the conveyor and thereby replacing the bad screen with the fresh screen. One of the units is generally entirely within the path, below the upper stretch and above the lower stretch.
