Abstract
Sheet transfer drum mounted between printing units within side walls of a rotary printing press includes two gripper bars arranged symmetrically on a circumference of the sheet transfer drum so as to be located diametrically opposite one another on a y-axis of the sheet transfer drum; a drum body core formed with side surfaces extending between the gripper bars over the entire length of the sheet transfer drum within the circumference of the sheet transfer drum and having a convex curvature with a curvature gradient which is largest in the region of the x-axis and diminishes continuously towards the gripper bars.
