Abstract
A sheet transport assembly is provided for transporting a sheet along a process unit configured for applying a process to the sheet. The sheet transport assembly includes: a conveying unit including a transport belt and a deflection element. The transport belt is configured for advancing the sheet in a transport direction along the process unit to the deflection element, the sheet being placed with a contact side on the belt and a process side towards the process unit. The deflection element is arranged in contact with the transport belt to deflect the transport belt downstream in the transport direction relative to the process unit. The sheet transport assembly further includes a separating unit for separating the sheet from the transport belt. The separating unit is connected to an air supply source. The separating unit includes a restrain blowing device arranged for directing a restrain air flow onto the process side of the sheet in a restrain area for urging the sheet towards the transport belt proximate to the deflection element. The separating unit further includes a lifting blowing device arranged for directing a lifting air flow onto the contact side of the sheet in a lifti…
