• before the stack of products is moved by the robot, pivoting the stack of products about a horizontal axis with a pivoting device that is different from the robot;
• with the stack of products being out of a horizontal position, aligning the stack of products and/or straightening the stack in one direction and/or straightening the stack in two directions perpendicular to one another and/or vibrating the stack and/or aerating the stack and/or modifying a fanned-out stack of products to become an unfanned stack of products;
• and
• subsequently taking over the stack of products by the robot from the pivoting device and subsequently moving the stack of products by the robot.
