Abstract
A sheet stack changing device for a sheet processing machine having a main stack lifting mechanism and a remaining-stack carrying device. The remaining-stack carrying device has bars for temporarily holding a remaining stack, a drive mechanism for moving the bars forward into the stack and retracting the bars from the stack in a staggered relation to one another. The remaining-stack carrying device is raised by a lifting mechanism. A pulling mechanism connects the bars with a carrying rail slidably engaged on the remaining-stack carrying device so that the carrying rail slides forward with the bars and retracts independently from the bars.
