Abstract: A sheet conveying device includes a belt arranged to carry sheets from an upstream end to a downstream end of a transport path, the belt having an array of perforations; and an array of suction nozzles arranged below the belt for sucking-in ambient air through the perforations of the belt. At least one blow nozzle is arranged at the downstream end of the transport path for blowing out a gas through the perforations of the belt. The downstream end of the transport path is defined by a deflection roller. A plurality of blow nozzles are formed by circumferential grooves in the peripheral surface of the deflection roller.

Abstract: A reproduction apparatus includes a print unit with print elements for ejecting an amount of ink on a plurality of sheets, of which each size in the direction perpendicular to the transport direction of the sheets under the print unit is smaller than the size of the print unit in the same direction, and a displacing mechanism for displacing the sheets in the same direction. The displacement of the displacing mechanism is so extreme that an alignment of a sheet is variable from an alignment of one side of the sheet with one end of the print unit to an alignment of the other side of the sheet with the other end of the print unit. Also a method for application by such a reproduction apparatus is disclosed.

Abstract: A printing system includes a marking engine for applying a marking substance onto a sheet and a sheet conveying device. The sheet conveying device includes a belt arranged to carry sheets from an upstream end to a downstream end of a transport path, the belt having an array of perforations; an array of suction nozzles arranged below the belt for sucking-in ambient air through the perforations of the belt; and at least one blow nozzle arranged at the downstream end of the transport path for blowing out a gas through the perforations of the belt. The conveying device further includes an array of anti-friction blow nozzles interleaved with the array of suction nozzles and connected to a blower for blowing-out a gas towards the bottom surface of the belt during the traverse of the sheet along the marking engine.

Abstract: The present invention provides a conveyor mechanism for conveying sheets. The conveyor mechanism comprises a movable conveyor body, a drive mechanism, and an adjustment system configured to detect and correct skewing of the conveyor body, comprising one or more markers provided on or in the conveyor body, a sensor arrangement for detecting each marker at two or more discrete positions, and a processor to determine the skewing of the conveyor body. The conveyor body and the drive mechanism of the conveyor mechanism are mounted on a movable conveyor frame, and the adjustment system includes a frame shifting device comprising one or one or more actuator for shifting or moving the conveyor frame relative to a fixed framework. The invention also provides a related method of correcting skewing in a conveyor mechanism for conveying sheets along a transport path.
