Claims
- 1. A process for the production of a uniform flow of particles to be discharged over the width of a hopper, such as fibers consisting of cellulose-containing or mineral-containing materials or fibers, chips or mixtures of such particles provided with binders for the production of boards from these materials by charging a hopper with a feeding device arranged above the hopper transversely to the longitudinal axis of the hopper and with a stationary feed to the side of the hopper that supplies particles to the feeding device, the process comprising the steps of arranging a horizontal endless belt conveyor with a discharge end above the hopper, shifting the entire conveyor in a back and forth direction so that the discharge end traverses the hopper from side-to-side thereof in a forward direction toward the hopper and a backward direction away from the hopper, driving the endless belt of the conveyor in the same direction at a given speed, shifting the entire conveyor back and forth at the same or higher speed as the belt of the conveyor to render the relative belt speed zero or higher when the entire conveyor is shifted in the forward direction toward the hopper and twice as high or higher than the belt conveyor when the entire conveyor is shifted in the reverse direction away from the hopper whereby the speed of the endless belt relative to the stationary feed remains the same when the entire conveyor is shifted back and forth, and supplying the width of the endless belt with material from the stationary feed.
- 2. A process according to claim 1 including the step of guiding the particles into the hopper as they are dropped from the discharge end of the endless conveyor belt.
