A sheet stacker comprising :
- A sheet flipping device for flipping a received sheet around a flipping axis with respect to an orientation wherein the sheet was received;
- A holding device for releasably holding at least a portion of the sheet at least partially during the flipping of the sheet by the sheet flipping device, wherein the holding device is configured for movement of the held portion of the sheet in a first direction perpendicular to the flipping axis;
- and
- a sheet supply path for supplying sheet to the sheet flipping device, wherein sheet supply path and the holding device are moveable with respect to one another between a first position wherein a portion of the sheet may pass into the sheet flipping device without being adhered against the holding device and a second position wherein the holding device is able to draw a portion of the sheet against it.
