Abstract

A blowing arrangement for a sheet-delivering device of a sheet-processing machine has a plurality of blowing nozzles arranged to be located above a sheet-delivering device and spaced from one another in a direction which is transverse to the sheet-transportation direction and at an angle to the sheet-transportation plane so as to blow air contrary to the sheet-transportation direction and between a sheet placed in the sheet stack and a sheet transported to the latter, wherein the blowing nozzles are also arranged at diverging angles to the sheet-transportation direction as considered in the sheet-transportation plane.
