<p>A semi-circular stack sheet feeding apparatus for supplying an imbricated stack of sheets to a sheet folding machine or the like is disclosed. The sheet feeding device has a delivery and diverting device for transporting the imbricated stack of sheets in a first delivery direction along the underside of a diverting drum, about a portion of the periphery of the drum and, in a second delivery direction, to a sheet removal platform. A removal device associated with the removal platform removes the uppermost sheet from the platform in a direction opposite the second delivery direction. A stop is provided on the removal platform against which the leading edges of the sheets strike and a stack height sensor is provided for sensing the number of sheets stacked on the removal platform. So long as the number of sheets in the stack is below a predetermined value, the stack height sensor maintains the drive of the delivery and diverting device engaged.</p> |
