Abstract
A sheet-guiding drum in a sheet-processing machine, comprises a gripper system, a gripper shaft, and a gripper tube. A method for producing a gripper system is also disclosed. The sheet-guiding drum further improves the sheet transport process, in particular the turning process, in sheet-processing machines. The problem addressed by the invention is in particular the provision of a low-wear rolling-element bearing that preferably eliminates the aforementioned disadvantages and, in particular, meets all further boundary conditions. This problem is solved in that the gripper tube is assembled from tube segments.
