Abstract

An apparatus for feeding and aligning sheets which are fed to a processing machine, e.g. a printing machine, includes at least two parallel transporting belts which, on a side directed toward the sheet, subject the sheet to different retaining forces, in such a way that the retaining force in outer peripheral regions is greater than in an inner region located therebetween. The transporting belts can be activated individually in dependence on the position of the sheet, and they can therefore align the sheet in its transporting direction and obliquely thereto.
