Abstract: A sheet-feeding device for the cyclic feeding of separated sheets from a sheet stack of a sheet feeder to a sheet processing machine or an onward conveying device is provided. The sheet-feeding device includes one or more first conveying rollers of relatively small diameter which are rotatably arranged close to the leading edge of the sheet stack of the sheet feeder and around which one or more endless drive tapes are guided, the latter starting from the first conveying roller, extending approximately in the conveying direction and wrapping around a second conveying roll that is arranged at a distance from the first conveying roller. The device also includes an upper conveying roller mounted above the first conveying roller for rotation about an axis parallel to the axis of the first conveying roller.
