Upon rotation of eccentric 1 about fixed axis B, lever 2 oscillates about fixed axis A. At this, lever 3, pivot ted to lever 2, engages pin 4 of link 16 in parallel-crank linkage AECD, and moves elevator 5 upwards, thereby lifting the next workpiece 6, delivered by the conveyer, into a stack. The workpieces are held in the raised position by clips 7. The stack of workpieces 6 reaches a definite preset height, after which lever 8 is deflected and pin a of lever 9 engages a clutch which is not shown. At this a special drive turns pivotted levers 10 and 15 so that pusher 11 shifts the finished stack onto the conveying device. After this, rotation of eccentric 1 is re-engaged. Workpiece 6 runs up against stop 12 which is in its extreme right-hand position when lever 2 turns downward. This is due to the fact that lug b of lever 3 turns angle lever 13 which, turning lever 14, shifts stop- lever 12 to its extreme position. Thus, owing to the action of stop 12, workpiece 6 is in a strictly definite position.
