<p>The invention relates to a channel, comprising guide means for objects (2), arranged in single file which are pushed by each other. The guidance means are comprised of a base (5), walls (6) and lateral walls (7). The channel has, along the length thereof, an automatic ejection zone (8) for debris (3, 4) of all kinds. In said ejection zone (8), the guidance means are partially removed, forming a window (9) or trapdoor, such as to permit a dropping of said debris by simple gravity. The substitute guidance means in said ejection zone comprise, for the base (5), a flat section (10), arranged within the field with a transverse offset and, for the lateral wall (7), a bar (13), extending between the two upper ends of said lateral wall (7). The window (9) has a length at least equal to the height of the objects and the width thereof is at least equal to the distance separating the walls (6) and lateral walls (7).</p> |
