    Abstract: A plurality of hoppers or bins which are product-loadable from above are uniformly spaced from each other and are transported along a path of conveyance. The hoppers or bins, each of which is bounded by two walls or faces which are substantially transverse to the direction of conveyance, pass by a plurality of individual infeed conveyors which are staggerdly arranged in the direction of conveyance. These individual infeed conveyors possess controllable grippers or clamps which are spaced from one another.
