<p>A plurality of laterally spaced apart, longitudinally extending, V-shaped upper conveyor slats (10) are provided. Each upper conveyor slat (10) has a crown and opposite side portions that slope laterally outwardly and downwardly from the crown. The side portions have lower surfaces. A plurality of laterally spaced apart, longitudinally extending, V-shaped lower conveyor slats (12) are provided. These lower conveyor slats (12) are positioned between the upper conveyor slats (10). Each lower conveyor slats includes a valley and side portions that slope laterally outwardly and upwardly from the valley. The side portions have upper and lower surfaces. The side portions of the upper conveyor slats (10) overhang the side portions of the lower conveyor slats (12). A plurality of slide bearings (14) are positioned vertically between the upper and lower conveyor slats (10, 12) where the side portions of the upper conveyor slats (10) overhang side portions of the lower conveyor slats (12). The slide bearings (14) have upper surfaces on which the lower surfaces of the side portions of the upper conveyor slats (10) slide. The slide bearings (14) also have spaces in which outer edge portions of the side portions of the lower conveyor slats (12) are received and slide. In use, the upper and lower conveyor slats (10, 12) reciprocate in a longitudinal direction and are supported for such movement by the slide bearings (14).</p> |
