Abstract
A sheet inverting and stacking system in which a rotatable sheet stacking unit receives the lead edge area of an incoming sheet and then rotates and releases that lead edge area of the sheet at a lead edge registration position for stacking the sheet inverted in a set of stacked sheets at least partially on a stacking tray in a stacking area; with a movable sheet registration system providing plural sheet lead edge registration positions; a sheet set fastening system (stapler) for fastening the stacked sets; a first registration position for set fastening in which the sheet stacking area extends into the sheet set fastening system and a second registration position in which the sheet stacking is in front of the sheet fastening system, to provide two different initial sheet leading edge stacking positions and one final stacking position. The rotatable sheet stacking unit is interdigitating with the movable registration system to carry the sheet lead edge directly into the first or second registration positions and also into the sheet fastening system in the first registration position. The stapler is under and at least partially inside of the rotatable sheet stacking unit, and the r…
