ablagevorrichtung for st. john sheets for printers or copiers

摘要

A copier/collator installation wherein the copier's output copy sheets are collated into sets in a multi-bin collator. The collator bins are vertically stacked.PPVertical stacking of the electrostatically charged and heated copy sheets, which therefore tend to curl, is enhanced by providing collator bins having electrically nonconductive walls. The bottom sheet-receiving walls are formed to have a generally concave cross section, facing upward. Considering the direction of sheet movement, this concave surface extends generally transverse the sheet movement. Pivoted and biased paper stabilizing wires hold down the leading portion of the sheet stack in the bin, and also absorbs the sheet's kinetic energy as the sheet enters the bin. A flexible, electrically nonconductive plastic flap, at the bin's entrance or mouth, holds down the sheet's trailing portion, and also absorbs the sheet's kinetic energy. A sheet discharging electrically conductive tinsel is mounted in the top of the bin, intermediate the stabilizing wire and the flap. This tinsel is mounted generally behind the flap so as not to physically engage the sheet.
