Abstract:
A device for forming a pile of sheets comprising:a pile carrier; said pile carrier comprising a pile supporting surface to receive sheets; a stop; said device for forming a pile of sheets defining an axis, the axis having an orientation in said device; said stop being configured and being disposed in said device for forming a pile of sheets so as to be pivotable with respect to the axis; a linear guide to guide the axis; said stop having a first alignment position on a first level relative to said linear guide and a second alignment position on a second level relative to said linear guide; structure to generate a first actuating force to pivot said stop about the axis; structure to generate a second actuating force to move said stop from the second alignment position toward the first alignment position; structure to pivot said stop around the axis and away from said pile against the first actuating force; said stop being configured to be raised from the first alignment position to the second alignment position and configured to retain the orientation of the axis by said stop being pivoted around the axis and away from said pile against the first actuating force, said stop being further configured to then be pivoted by said structure to generate a first actuating force toward said pile; said stop being configured to be pressed against the pile supporting surface by said structure to generate a second actuating force upon said stop being in the second alignment position; said linear guide being configured and disposed to force a linear vertical dislocation of the axis upon movement of said stop; an end stop; said end stop comprising a vertical support surface; and said vertical support surface of said end stop being disposed to limit pivoting of said stop to align said stop substantially identically under the influence of the first actuating force at the first and second levels and at every intermediate position of said stop between the first level and the second level.
