ABSTRACT:
For use with an apparatus for feeding sheets seriatim from a stack of sheets, the apparatus including a feed tube, such as an oscillating vacuum feed tube for example, defining a plurality of ports through which vacuum is effective for acquiring a sheet from a sheet stack and transporting such sheet from the sheet stack, a device for improving sheet separation and friction feed assist. The disclosed device includes at least one clip associated with at least one port of the feed tube. A friction member is secured to the clip and extends substantially radially outwardly from the oscillating vacuum feed tube so as to cause an acquired sheet to assume a corrugated shape. Accordingly, a sheet of the sheet stack, acquired by the feed tube, assumes a corrugated shape to readily separate from the remaining sheets in the stack, and the friction member assists in feeding of such acquired sheet from the stack.
