Abstract
A feed apparatus ( ) comprising a conveyor belt ( ), the conveyor belt ( ) comprising modules ( ) with an upper ( ) and a lower ( ) surface, the modules ( ) comprising hinge eyes ( ) pivotally hinged to each other perpendicular to the feed direction. The feed apparatus ( ) comprises at least one rotatable and toothed driving wheel ( ) meshed with the conveyor belt ( ), with the pressure receiving surface ( ) of the teeth wholly or partially in contact against at least the outer surface ( ) of its own hinge eye ( ). Therefore an optimum force transmission to the belt itself is achieved, which occurs through the teeth of the sprocket wheel applying driving force at the hinge eyes, thus making the force transmission occur close to the center line of the axis of the hinge eyes. There is a good lateral steering of the belt, so that the risk that the belt hops off the toothed wheel is minimized.
