ABSTRACT:
A sheet delivery device is provided that allows for high output and accurate operation during changing of the main stack. The device includes two secondary stack carriers which are normally disposed on opposite sides of the main stack in a first lateral waiting position. The secondary stack carriers are reciprocally moveable between the first lateral waiting position and an operative position. In the operative position, the secondary stack carriers accumulate a secondary stack while the main stack is being changed. This secondary stack is later deposited on the new main stack. Cooperating with the secondary stack carriers are separating elements normally disposed above the secondary stack carriers in a second lateral waiting position. The separating elements are reciprocally moveable between the second lateral waiting position and a separating position. In the separating position, the elements accumulate a temporary stack to form an entry gap above the main stack. The secondary stack carriers, which are plate-like enter this entry gap to arrive at the operating position. The separating elements thereafter deposit the temporary stack on the secondary stack carriers to form the secondary stack.
