A sheet transfer method for carrying a predetermined number of sheets from a destacking position to a restacking position by a vertically and horizontally movable transfer unit incorporating an entry-conveyor, a mid-conveyor, and an exit-conveyor. In this method, at the time of destacking a pile from the remaining stack, the advance of the transfer unit from one end to the other end of the stack, and the rotation of the pair of the entry-conveyor and mid-conveyors are concurrently effected substantially at the same speed, but in directions opposite to each other until the pile is progressively supported on the mid-conveyor. After the arrival of the transfer unit at the restacking position, the retraction of the transfer unit toward the destacking position, and the actuation of the pair of the mid-conveyor and exit-conveyor are concurrently effected substantially at the same speed, but in directions opposite to each other until the pile is clear of the transfer unit. |
