ABSTRACT:
In a device for advancing several workpieces placed side by side, a slide comprises several thin plates arranged alongside of one another. These thin plates are positionable against the workpiece end remote from a stop and are movable back and forth over a predetermined compensation distance parallel to the direction of advance of the workpieces. The compensation distance is longer than the greatest difference in length between the workpieces. The thin plates are prestressed by an energy accumulator which exerts a force which is larger than the force required for the advance of the workpieces. A first switch is arranged on the slide to switch off the slide drive as soon as one of the thin plates is displaced beyond the compensation distance in the direction opposite to the direction of advance.
