ABSTRACT:
A movable grill is mounted in a frame in such a way that the grill is capable of being moved a certain distance above a feed table towards an ejection point and a suction device is mounted above the section of the grill which moves towards the ejection point. An air-tight rear sealing skirt is suspended from the frame to enclose the space found between the afore-mentioned section of the grill and the top of a pile of sheets on the feed table; and a forward air-tight sealing skirt is suspended from the aforementioned section of the grill above the ejection point such that the vacuum created by the section means causes eddies of air around the edges of the pile of sheets in such a way that the top sheet of the pile of sheets is caused to vibrate and is drawn up to the section of the grill in order that the top sheet is moved with the grill towards the ejection point.
