Abstract
The stacking machine for making stacks of adjacent disk-like workpieces, e.g. metal covers, has a conveyor trough along which a column of workpieces being divided into stacks moves in its longitudinal direction until the stacks reach an unloading station. To maintain a space between successive stacks spherical spacers are inserted between the stacks into a gap formed there by the feed mechanism. A return trough inclined to the conveyor trough running from the unloading station to the feed mechanism is provided for feed back of the spherical spacers. This return trough may be mounted beside or below the conveyor trough. Only a very minimal construction expense is necessary to maintain the gap between the stacks and to feed back the spherical spacers which is effected because of the action of gravity alone.
