Abstract: In a stack changing device, on a sheet feeder the remaining stack bars (7A, 7B) are pulled from the stack area, out-of-line in relation to each other. For improved stack joining, the inner remaining stack bars (7A, 7B) are each pulled more slowly than the outer remaining stack bars (7A, 7B).

Abstract: In a non-stop stack changing device, remaining-stack bars are pulled from the stack area one by one and out-of-line in relation to each other. To this end, a pull/push drive is provided, which makes it possible to push the remaining-stack bars simultaneously into the grooves of a pallet carrying a sheet stack. Furthermore, the pull/push drive makes it possible to pull the remaining-stack bars in pairs from inside outwards out of the stack area. In addition, the remaining-stack bars can be pulled in a first and second sequence in accordance with this model. An individual motor drive is provided for this purpose, which operates interlockingly on each individual remaining-stack bar.
