Abstract
Methods and apparatus for stacking predetermined sheets of various intermixed sizes in a stacking location by advancement of stacking devices into that location, selectively guide further sheets past the stacking location. That guiding of further sheets past the stacking location is mechanically slaved to the advancement of the stacking devices into the stacking location. Where the stacking devices are withdrawn from the stacking location preparatory to each stacking of a predetermined sheet, the guiding of that predetermined sheet into the stacking location is mechanically slaved to such withdrawal of the stacking devices. Where the sheets are stacked against a movable wall, an unobstructed space for receiving each sheet guided to the stacking location is permanently preserved between the movable wall and the withdrawn stacking devices.
