Abstract: Disclosed is a paper feeding device (10) comprising a storage surface (14) for a stack of papers (12) adapted to be moved vertically. The device further comprises a vacuum feeder (16) for feeding papers from their position on the storage surface (14) and imparting on an uppermost sheet of paper (12a) a horizontal displacement, and a blower arrangement (18, 20) adapted to provide a curtain of air separating the uppermost sheet of paper (12a) from the rest of the stack of papers. The device further comprises an upper paper stop (26) displaceable between a lower position and an upper position, wherein, in the lower position, an underside of the upper paper stop (26) is aligned with an underside of the vacuum feeder (16), and wherein, in the upper position, the underside of the upper paper stop (26) is above the level of the side guides.
