In press line operations, a workpiece conveyor device is necessary to carry workpieces from one press to another. Preferably, this conveyor should be readily removable for repairs, adaptable to a large number of presses, and readily reprogrammable to adapt to a variety of workpieces. To achieve this, a conveyor is provided having a cross member mounted on a movable carriage which moves along a track on a frame bridging the intermediate space between two presses. Horizontal movement of the carriage along the track, vertical movement of the cross member on the carriage, and movement of a positioning device for the workpieces is provided by setting drives controlled by a continuous-path numerical control unit. For repairs, the entire frame can be moved out of the intermediate space in a direction at a right angle to the direction of workpiece travel.
