A longitudinal conveying system (10) for mechanically feeding one or more workpieces (12) to a predetermined loading position, comprising a pair of spaced, parallel longitudinal workpiece supports (15), with each such supports including an upper support face and having a distal end and a proximal end. A loading position (13) is located adjacent the proximal end of the workpiece supports (15), and a longitudinal conveying beam (20) is moveably located intermediate the workpiece supports (15). The conveying beam (20) has an upper surface (21) for supporting one or more workpieces (12). Driving means (36, 45) for moving the conveying beam (20) in an upward direction, a forward conveying direction toward the proximal end, a downward direction, and a backward direction is provided for enabling the conveying beam (20) to lift workpieces (12) from the workpiece supports (15) for movement toward the proximal end. The downward movement is substantially vertical, and the upper surface of the conveying beam (20) is lowered below the upper workpiece support faces prior to the backward movement.
