The apparatus has a preliminary stacking device (22) arranged above a stacking shaft (12). A number of base elements (50) move into and out of a preliminary stacking shaft (24). The base elements are arranged sequentially along a continuous circulatory path (51). A drive arrangement (47) drives the base elements in a working portion (85) of the path along a movement direction (U) oriented from top to bottom such that the elements are moved to a feed unit (28) when an intermediate stack (20) is formed on an immediately preceding base element. |
