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).
