Abstract
A stacker preferably includes two units, each having three storage drums which are arranged one above the other and which can be rotated independently of each other, and a feed device for carrying printing plates to the storage drums and arranged between the units. Further arranged between the storage drums is a drum loader for receiving printing plates from the feed device and for inserting the received plates into empty storage cells of the drums. The drums can be rotated independently of one another in a clockwise or a counterclockwise direction, for insertion or removal of the printing plates, which may be offset plates or other printing plates which must be handled very carefully.
