A medium feeding apparatus includes: a placement mount on which a plurality of media are placed; a transportation mechanism that transports an uppermost medium of the plurality of media placed on the placement mount; a floating-air blowout mechanism that blows out air to float at least the uppermost medium; a suction mechanism that sucks air to cause the uppermost medium floated by the floating-air blowout mechanism blowing out air to be attracted to the transportation mechanism; and a floating-air control unit that causes the floating-air blowout mechanism to start to blow out air while the uppermost medium is being attracted to the transportation mechanism after starting to be transported by the transportation mechanism, so as to float at least a second medium located below the uppermost medium, and causes the floating-air blowout mechanism to stop blowing out air before the second medium starts to be transported by the transportation mechanism.

The invention relates to a device and a method for stacking card-like data carriers. The device comprises (i) a conveying device for transporting individual card-like data carriers downstream along a conveying path and (ii) a stacking unit for selectively transferring and stacking card-like data carriers conveyed along the conveying path. The conveying device is arranged to convey the card-like data carriers in such a way that they are fixed to it in a hanging mode of transport. The stacking unit is arranged to selectively release certain ones of the card-like data carriers conveyed along the conveying device from the latter in order to transfer them directly—i. e. in particular without intermediate processing, intermediate transport or intermediate storage—into a card magazine and to stack them therein when the card magazine is arranged in a stacking area at a stacking position which, in relation to the direction of gravity, is situated below the conveying path.

The invention relates to a device, in particular a roll cross-cutter, for forming a shingle stream of underlapping or overlapping sheets, in particular of paper or carton sheets, having a transport apparatus for transporting sheets, having a shingling apparatus for underlapping or overlapping sheets in regions, having a deceleration apparatus, downstream of the shingling apparatus in the transport direction of the sheets, for decelerating shingled sheets, in particular by forming a deceleration gap for the passage of shingled, combined sheets, and, preferably, having a cross-cutting apparatus upstream of the shingling apparatus for cutting a material web into individual sheets. According to the invention, the shingling apparatus is designed to be adjustable, in dependence of the cut length, in and/or opposite the transport direction of the sheets.

According to some embodiments a conveying device for conveying goods includes at least one conveyor belt with an outer contact face against which the goods to be conveyed are held during conveyance. A main negative pressure holding area is provided adjacent to the conveyor belt, the main negative pressure holding area being configured to hold or release the goods to or from the conveyor belt by negative pressure. The conveyor belt includes at least one suction chamber on the outer contact face forming an additional negative pressure holding area, the suction chamber being in fluid communication with negative pressure holding means through at least one opening transversely going through the conveyor belt.

Apparatus is provided for manufacturing a wipe in a three dimensional form out of an essentially flat piece of material. The apparatus produces a blank (12) of essentially flat planar form with a pleat folded on each side. The folded blanks are fed by a conveyor belt (21) to an opening station (22). The opening station comprises a pair of movable pinch rollers (34, 35) which selectively grab individual blanks from the conveyor belt and feed them via belts (32, 33) to a pair of counter-rotating drums (30, 31). The blanks are ejected from the drums, which partially opens them up in the process. The partially open blanks are fed onto a shaped former (37), where the final process of forming the wipe into its chosen three dimensional form is completed.

A belt conveyance device includes an endless belt, a duct having a suction port, and a rectifier inside the duct. The duct is surrounded by an inner circumferential surface of the endless belt. The rectifier extends in a width direction of the endless belt perpendicular to a direction of conveyance by the endless belt.

A suction mechanism for suctioning a loop transporting belt a medium processed by a processing unit, a rotation mechanism for rotating the transporting belt, a stacker for stacking the medium transported by the transporting belt, and a change mechanism for changing a movable area are included. The rotation mechanism, after suctioning the medium to the transporting belt to rotate in a first rotation direction to transport the medium in a first transport direction, rotates the transporting belt in a second rotation direction to transport the medium in a second transport direction to stack the medium on a stacker. The change mechanism narrows a movable area when the medium is transported in the second transport direction compared to an area when the medium is transported in the first transport direction.

A paper feed mechanism includes: a paper storage to store sheets of paper; an air blowing unit disposed on each of both sides of the paper storage in a second direction orthogonal to a first direction corresponding to a paper conveyance direction, in which the air blowing unit blows air to a side end of each of the sheets of paper in the paper storage to float one or some of the sheets of paper in the paper storage; and a paper conveyance unit disposed above the paper storage, in which the paper conveyance unit holds, by suction, an uppermost sheet of paper among the floated sheets of paper, and conveys the uppermost sheet of paper. An air blowing position of the air blowing unit is changeable in the first direction according to information about the sheets of paper.

A medium supply apparatus includes: a placement mount on which a plurality of media are placed; a transportation mechanism that transports an uppermost medium of the plurality of media placed on the placement mount; and an aspiration mechanism that aspirates air to attract the uppermost medium to the transportation mechanism, wherein the aspiration mechanism includes a blocking means for blocking air aspiration performed by the aspiration mechanism, in such a manner as to prevent another medium of the plurality of media that is located below the uppermost medium from being attracted to the transportation mechanism.

A medium discharge includes a first tray having a first medium receiving surface, a second tray having a second medium receiving surface for receiving the medium discharged from the first tray, a discharge section that discharges the medium disposed on the first tray to the second tray, and a push-down portion that is located downstream of a downstream end of the first medium receiving surface in the medium discharge direction, and that is located at a place deviated from the discharge section in a width direction that is a direction intersecting with the medium discharge direction, and pushes down a part of an upstream end of the medium to be discharged in the medium discharge direction.
