Abstract

A sheet transfer drum of a multi-color sheet-fed rotary printing press. A central drum body with flat portions carries at least one gripper system which extends over the sheet width. Jacket segments are mounted on the flat portions of the drum body. The jacket segments are exchangeably attached and they are formed with an inflatable interior. When they are deflated, the jacket segments fold into the flat portions of the drum body.
