Abstract
A sheet accelerating device driven by the single-revolution shaft of a feeding attachment with a front-feed unit which runs faster or slower than the single-revolution shaft is constructed in such a way that high feeding accuracy is also guaranteed at high operating speeds, and this is achieved by the provision of an intermediate gear between the advancing unit and the single-revolution shaft, the intermediate gear having a step-by-step motion gear and control gear which allows adjustment of the speed of the rotating element of the step-by-step motion gear for a part of its rotation in relation to the speed of the single-revolution shaft.
