ABSTRACT:
An input station for a belt conveyor of the kind including a continuous conveyor belt that moves in a conveyor run through an input station to a discharge location, around a head pulley, and in a return run around a tail pulley back to the input station and the conveyor run. At the input station the conventional center support rollers are retained but the support rollers along the sides of the belt are replaced by a plurality of elongated, stationary, flat support members that support the sides of the conveyor belt throughout the input station, improving the seal to input station skirtboards and materially reducing or eliminating input leakage while maintaining roller support and flexibility in the center of the belt, with minimal friction increase.
