Abstract

The invention relates to a method of transporting sheets in a digital printing machine.
The invention is characterized in that an individual sheet in a transport loop can essentially be negatively accelerated and essentially be positively accelerated.
Further, the invention relates to a device for transporting a sheet, in particular after a sheet has been picked off a stack and separated.
In accordance with the invention, this object is achieved in that the sheet is continuously accelerated from a stopped state to a transport speed.
