Abstract:
A process for automatically and continuously changing a sheet stack in a sheet feeder of a sheet-processing machine including a remaining-stack carrying device having remaining-stack bars, the sheet stack having a pair of opposing stack edges and a middle area interposed between the opposing stack edges, the stack changing process comprising the steps of:temporarily receiving a remaining stack from a pallet on the remaining-stack bars by sliding the remaining-stack bars underneath said remaining stack from a common side of the stack into a stack position, continuously raising said remaining stack with the remaining-stack bars, and depositing said remaining stack on a newly fed-in sheet stack which has been moved into position below said remaining stack by sequentially removing the remaining-stack bars from the stack position starting with at least one of the remaining-stack bars in the middle area of the sheet stack and then progressively removing others of the remaining stack bars progressing outwardly to the remaining-stack bars adjacent the opposing stack of the sheet stack.
