Abstract
An apparatus for feeding sheets one by one from a group of at least partially overlapping sheets, in which a conveyor belt in contact with the lowermost sheet is driven to feed that sheet in the desired transport direction while a sheet separating roller forming a nip with the belt is driven so as to move the surface of the roller through the nip in the opposite direction, thus holding back of the nip sheets lying on the lowermost sheet, is provided with a displaceable member, for example a flat end portion of a leaf spring wound into a spiral, which has a smooth underside to receive under this member and press on the sheets approaching the nip and has a forward end edge slidably engaged with the surface of the roller immediately adjacent to the location where the sheets contact the roller. The displaceable member prevents the sheets from curling up or buckling in the vicinity of the roller, irrespective of the number of sheets and irrespective of variations of the position of the separating roller.
