摘要： A medium supply device includes: a stacking unit in which media are stackable in a vertical direction; a first regulating unit that is provided on the stacking unit and that regulates positions of side portions of the media in a width direction; a supply unit that supplies air to more than one of the media stacked on the stacking unit so that the more than one of the media are raised and separated from each other; a transport unit that successively feeds the media that are raised and separated from each other by the supply unit; a detection unit that detects conditions of the media that are raised and separated from each other by the supply unit from outside in the width direction; a second regulating unit that is attached to an upper section of the stacking unit when the media stacked in the stacking unit are second media and that regulates positions of side portions of the second media in the width direction, the second media having a smaller dimension than first media in the width direction; and a moving unit that moves the detection unit to an area in which the second media are detectable when the second regulating unit is attached.

摘要： In some examples, a sheet-processing machine includes a transport unit for transporting sheets. The transport unit includes a feed roller configured as an infeed roller and a feed roller configured as a diverting roller, which define a transport plane of sheets. At least two further feed rollers of the transport unit are arranged outside the transport plane. At least one feed roller of the at least two further feed rollers is configured as a pivoting roller that pivots and/or that can be pivoted about a pivot axis. The pivot axis of the pivoting roller is an axis that is normal of an axis of rotation of the pivoting roller, and the pivoting roller is configured to automatically pivot about the pivot axis.

摘要： Alignment apparatuses include a frame and contact elements connected to the frame. The contact elements contact items that are to be transported in a processing direction relative to the frame. The contact elements are in permeant fixed positions relative to the frame, and do not move relative to the frame. Adjustable mounts are connected to the frame and move the frame in the processing direction and in a perpendicular cross-processing direction. A controller is electrically connected to the adjustable mounts, and the controller is adapted to control the adjustable mounts to simultaneously move the frame and all the contact elements in the cross-processing direction and the processing direction while rotating the frame. Methods laterally shift imaging on sheets that have had rotational correction performed by such alignment apparatuses.

摘要： A bonding apparatus includes a first holder, a first transforming device, a second holder, a second transforming device, a suction device and a control device. The first holder attracts and holds a first substrate from above. The first transforming device transforms the first substrate held by the first holder such that a central portion of the first substrate is protruded downwards. The second holder is provided under the first holder, and attracts and holds a second substrate, which is to be bonded to the first substrate, from below. The second transforming device transforms the second substrate held by the second holder such that a central portion of the second substrate is protruded upwards. The suction device generates different attracting forces in multiple division regions included in an attraction region of the second substrate. The control device controls the suction device.

摘要： A medium feeding device includes a storage unit that stores media in a form of a sheet, a delivery unit that is disposed downstream in a medium delivery direction relative to the media stored in the storage unit and that delivers the media individually, a transfer unit that is disposed above the storage unit and that sticks by suction to each of the media stored in the storage unit and transfers the media to the delivery unit individually, and a fluffing unit that is disposed beside the media stored in the storage unit in a direction intersecting the medium delivery direction. The fluffing unit fluffs an upper-side region of the media in a state of being separated by blowing air toward a side of the media. The medium feeding device further includes plural position detection units that are arranged in a region that is on the delivery unit side relative to a position of a downstream end portion, in the medium delivery direction, of each of the media stored in the storage unit and that does not reach a contact portion where the delivery unit comes into contact with the media. The position detection units are arranged at an interval in a width direction of the media intersecting the medium delivery direction. The position detection units detect a position of the downstream end portion, in the medium delivery direction, of each of the media.

摘要： Apparatus, methods, and systems for a vacuum conveyor for inkjet printing with adjustment to the covered area are disclosed. In some embodiments, a controller of a vacuum conveyor expands first one or more actuators of multiple first actuators of a substrate transportation system to decrease a suction width of an area of suction provided by the vacuum conveyor in accordance with a substrate width of a substrate being inkjet printed using the vacuum conveyor. A second one or more actuators of the multiple first actuators being retracted. The controller retracts multiple second actuators of the vacuum conveyor to increase the suction length of the area of suction while the substrate transportation system moves the substrate along the vacuum conveyor for inkjet printing of the substrate. The controller expands the retracted actuators of the multiple first actuators to increase the suction length as the substrates exit the vacuum conveyor.

摘要： 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.

摘要： A device for processing of flat elements, especially for the processing of paper blanks, is described. This device comprises a conveyor belt (25) that is guided over a first roller (12a) and a second roller (12b), said conveyor belt being made of metal and being permeable to air, wherein its upper section forms the transport section (25a) and its lower section forms the return section (25b), and a vacuum generator being located under the upper section of the conveyor belt. A laser (30) for cutting the flat elements is located above the transport section (25a). In order to achieve an improved flatness and an increased durability, the conveyor belt (25) consists of an expanded metal.

摘要： A vacuum belt conveyor sequentially delivers sheet articles to a digital printer. The sheets are held in position by vacuum on the underside of the sheets through apertures in the belts and covered by the sheets. A plurality of independent plenums on the underside of the belt have chambers respectively communicating with rows of apertures extending along the belt. Vacuum is selectively applied from a manifold only to the plenum chambers that supply apertures that are covered by the sheets so that the ink from the printer will not be directed from its intended position on the sheet by vacuum from adjacent uncovered belt apertures. The sheets are fed to the conveyor in synchronism with the conveyor speed by a timed feeder so that the sheets are carried by the conveyor with a predetermined gap between the sheets and no belt apertures in the gap. A sensor counts the apertures in the belt and activates the feeder at predetermined time intervals.
