Claim 0:
1. A device for changing a sheet pile in a sheet feeder for a sheet treating machine, the device comprising:
a main pile supporting unit comprising a supporting surface adapted to support a pallet carrying a sheet pile; and
a residual pile supporting unit
comprising a plurality of residual pile bars extending substantially parallel to each other and being substantially parallel to the supporting surface,
the plurality of residual pile bars are coupled to a bar actuating unit adapted to move the plurality of residual pile bars into a sheet pile region and retract the plurality of residual pile bars from the sheet pile region,
the plurality of residual pile bars are arranged in the residual pile supporting unit-such that the plurality of residual pile bars are positionable in respective slots of the pallet being supported on the main pile supporting unit when the plurality of residual pile bars are in the sheet pile region,
each of the plurality of residual pile bars are movable within a predefined range of movement in a direction substantially orthogonal to the supporting surface, and the plurality of residual pile bars are movable independently from each other.
