  • Patent number: 8435022
    Abstract: The invention relates to a dispersion installation for dispersing dispersible material on a dispersing material conveyor belt so as to form groups of material for producing wood-material boards. Said system comprises at least one dispersion material bunker for the dispersible material dispersed on the dispersing material conveyor belt, having at least one top side filling opening. A chute is connected to the filling opening via which the dispersible material can enter into the dispersion material bunker. The invention is characterized in that at least one brake cylinder device is arranged inside the chute, said brake cylinder comprising at least two rotationally driven brake cylinders.

  • Patent number: 7770715
    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.
