ABSTRACT:
A sheet-conveying drum for skew register correction in multicolor printing that does not affect the drive in sheet-fed rotary presses. The sheet-conveying drum comprises gripper bars and support or carrying webs that are disposed on a drum shaft. The web disposed nearest the drive input has on its flange an arcuate bearing surface around which the drum body can be skewed relatively to the drum shaft. The web disposed opposite the drive input is coupled to an adjusting eccentric bushing by way of a flange to cause the drum to skew. The movements of drum skewing do not adversely affect the drive and, therefore, the transmission ratios of the sheet-guiding cylinders relative to one another.
