    Abstract: A sheet separating and feeding apparatus has a separating device and a vacuum-attracting device to separate and feed sheets one by one from piled sheets. The separating device includes a compressed air plenum chamber, and main nozzles, first auxiliary nozzles and second auxiliary nozzles which are provided on the compressed air plenum chamber for causing air to blow to an upper portion of the piled sheets to separate the uppermost sheet from the remaining sheets. The vacuum-attracting device includes a vacuum chamber and an endless belt having a plurality of through holes provided in a part of the belt. The endless belt rotates around the vacuum chamber, and attracts the uppermost sheet which is separated by the separating device, when the through holes intermittently communicate with a negative pressure in the vacuum chamber. The endless belt is driven it different speeds according to the rotational positions of the through holes, such that the rotational speed of the belt is increased until the belt reaches a position for attracting a next sheet after it has fed the uppermost sheet.

    Abstract: A pneumatic sheet separating device is provided whereby sheets in a holder can be discharged one by one from the bottom of a stack and wherein the holder is provided with a carrier and lateral supports. The carrier is permanently bent or depressed transversely of the direction of sheet transport such that it is nonplanar. In the vicinity of the deepest part of the bend or depression, the carrier is preferably provided with at least one aperture beneath at least one edge zone of a side edge of the stack of sheets in the holder, wherein a partial vacuum can be created so that the bottom sheet is sucked against the carrier. An air duct is also provided to blow air against the side edge of the stack, as considered with respect to the direction of sheet transport, to create a layer of air at least between the bottom sheet and the stack thereabove. Preferably the air duct is disposed so that the air flow is blown out over the deepest part of the carrier causing the friction between the bottom sheet which is to be discharged and the stack thereabove to be reduced. At the instant that the layer of air forms between the bottom sheet and the stack thereabove, the bottom sheet is discharged by a transport belt.

    Abstract: A device for sequentially introducing sheets placed in a stack into the nips of a pair of introduction rollers comprising at least one linear member having ends secured to a control pulley or roller and passing around a return pulley or roller which is adjacent the nips of the introduction rollers. A plurality of cams mounted on rotating shafts for engaging a run of the linear member to shift it from a retracted position to a position for engaging a bottom sheet in a stack disposed above the linear member, a vacuum chamber disposed along each linear member for holding the sheet on the members as they engage the sheet and carry it toward the nips.
