Abstract

See full text

A printing system includes an endless metal transport belt for transporting sheets in a transport direction, wherein the metal transport belt comprises multiple through holes through which an underpressure or overpressure may be applied on the sheets, a sheet separation system for separating the sheets from the metal transport belt by applying a local overpressure, and a sheet separation guide which guides the separated sheets away from the metal transport belt. The sheet separation system includes a stationary sliding surface, wherein the metal transport belt slides over the stationary sliding surface, wherein the stationary sliding surface includes a number of blow holes which define the overpressure zone, and wherein the blow holes are configured to apply a local overpressure in the overpressure zone through the metal transport belt onto the underside of the sheets. The overpressure zone is formed in the curved part of the stationary sliding surface, wherein the overpressure zone has an upstream end and a downstream end, which are defined by the location of the blow holes, and wherein the sheet separation guide directly adjoins the overpressure zone at the downstream end thereof.
