Abstract
In a process for the production of a uniform flow of particles to be discharged over the width of a hopper, such as cellulose or mineral fibers or glue-coated chips or mixtures for the production of boards consisting of these materials, a feeding device is arranged above the hopper transversely to the longitudinal axis of the hopper for discharging particles into the hopper. A stationary feed arranged to the side of the hopper supplies particles to the feeding device. The feeding device includes a horizontal belt conveyor which carries the particles from the stationary feed to the hopper. The entire feeding device moves back and forth during this procedure whereby the particles are deposited into the hopper from one side thereof to the other. This prevents or substantially eliminates the particles from lumping or sticking together in the hopper which might otherwise occur if the particles were simply directly supplied to the hopper from a stationary source.
