Abstract
The lowermost sheet of an upright stack of superposed sheets is removed by a device which has one or more suction heads and is moved against the underside of the lowermost sheet prior to folding one or two marginal portions of such sheet downwardly to separate the marginal portions from the adjacent portions of the next-to-the-lowermost sheet. The device thereupon moves the lowermost sheet downwardly, substantially at right angles to the plane of the next-to-the-lowermost sheet, either into the range of one or more tongs or analogous transfer elements, or directly to the periphery of a rotary turret in a cigarette packing machine. Once the marginal portion or portions of the lowermost sheet are flexed downwardly, the corresponding marginal portion or portions of the next-to-the-lowermost sheet are engaged and held by one or more pivotable retaining members which are disengaged from the sheet as soon as the device returns to its raised position and attracts and supports the next lowermost sheet.
