A conveying apparatus for feeding sheets into a processing apparatus is discloses which comprises a plurality of nips within which sheets are gripped and driven along a conveying direction towards the processing apparatus, each nip being defined between a respective drive wheel and an opposing reaction surface. The drive wheels are omni-wheels configured to apply a frictional force to advance the sheets in the conveying direction while permitting free movement of the sheets in a direction transverse to the conveying direction, the reaction surfaces permitting free movement of the sheets in the transverse direction, and an elongate guide is arranged on one side of the conveying apparatus, to extend generally parallel to the conveying direction, the conveying apparatus being configured to urge conveyed sheets in the transverse direction into contact with the guide. A control system is provided to move the guide generally in the transverse direction in dependence upon sensed fiducials on the conveyed sheets, to ensure correct alignment of the sheets in the transverse direction with respect to the processing apparatus.

A sheet conveyor is provided for transporting a sheet. The sheet conveyor includes a supplying conveyor, a receiving conveyor and a sheet guidance unit. The receiving conveyor includes a support surface arranged for supporting the sheet on a contact side of the sheet and an attraction unit arranged for attracting the sheet to the support surface. The supplying conveyor includes a transport belt being arranged for advancing the sheet in a transport direction along a transport path towards the support surface of the receiving conveyor; the sheet having two side edge portions relative to the transport path. The sheet guidance unit is arranged at a downstream end of the transport path for guiding the sheet towards the receiving conveyor, wherein said sheet guidance unit includes a lifting element arranged for lifting both side edge portions of the sheet away from the support surface while a middle portion of the sheet in between both side edge portions is guided towards the support surface.

Disclosed are a method and a device (1) for handling individual intermediate layers (5). The method involves removing from each of at least two separate stacks of intermediate layers (7) an individual intermediate layer (5) arranged topmost on the particular stack of intermediate layers (7). The removed individual intermediate layers (5) are moved into a detection range of a sensor system (13) of its own and the particular own sensor system (13) identifying, preferably by means of optical detection, an outer edge (6) of the particular intermediate layer (5). Subsequently, the removed individual intermediate layers (5) move toward a particular target location (Z1, Z2), the particular, preferably optical detection thereby being taken into account, such that the intermediate layers (5) reach their particular target location (Z1, Z2) in a predetermined position.
