PROBLEM TO BE SOLVED: To prevent dispersion in an impregnation amount of a prescribed chemical liquid, and to prevent deterioration of easiness of takeout by increasing an impregnation rate of the prescribed chemical liquid.SOLUTION: A press device 15 includes: a plurality of rollers 201, 202, 203; press belts 204a, 204b wrapped around the plurality of rollers 201, 202, 203; and conveyance belts 205, 206 conveying a stacked body 800. At least one roller of the plurality of rollers 201, 202, 203 drives the press belts 204a, 204b at a prescribed conveyance speed to a prescribed conveyance direction. The press belts 204a, 204b are disposed with a gap in an intersection direction CD perpendicular to the conveyance direction MD such that the press belts 204a, 204b can abut on both end portions 800A, 800B of the stacked body 800 in the intersection direction CD.

PROBLEM TO BE SOLVED: To form a stack at high speed while feeding sheets at low speed to prevent curls and tip damage of the sheets. SOLUTION: Sheets 8 entering to a zone 310 at predetermined speed one by one are sequentially sent to a next zone 320. The zone 320 receives sheets shorter than the length of the zone 320. Inside the zone 320, pinch nips 320A-320E for carrying sheets 4-7 at low speed are arranged, and the sheets are sequentially shingled with each other and are continuously sent out. In a next zone 340, a plurality of suction feeding sub-assemblies 340A-340E for carrying tip sides of sheets 1-3 by vacuum suction, respectively are arranged at intervals less than or equal to the length of a shift between sheets in the process direction. While shingled, the sheets are carried and sent out from the final stage sub-assembly 340E to a zone 350 one by one. In the zone 340 as a whole, a plurality of sheets can be carried simultaneously.

PROBLEM TO BE SOLVED: To provide a method and a device for printing a corrugated board sheet which can secure a high-quality printing image. SOLUTION: This device is equipped with a conveyor belt with a punched hole or a pore extending there through, a plurality of inkjet nozzles which are arranged intersecting the conveyance direction of the conveyor belt at an interval above or below the liner surface of the corrugated board sheet to be printed, a suction chamber which communicates with the punched hole or the pore of the conveyor belt at a spot for an inkjet printing unit in order to apply a suction to the corrugated board sheet and urges the corrugated board sheet to the conveyor belt, and a control means which selectively controls a suction region communicating with the punched hole or the pore of the conveyor belt at the spot for the inkjet printing unit and reduces substantially the size, in the crosswise direction, of the suction region, compared with the width of the corrugated board sheet.

PROBLEM TO BE SOLVED: To provide a paper reversing and carrying mechanism having a reduced size while preventing the occurrence of printing stain due to a contact member, and also to provide a paper reversing and carrying device equipped therewith. SOLUTION: The paper reversing and carrying mechanism 1 is provided for carrying paper 10 to a first direction, reversing it from one side to the other side, and then carrying the reversed paper to a second direction. It comprises: a first carrying part 2 for receiving one side 101 of the paper with a carrying face 21 and carrying the paper to the first direction (an arrowmark S); a paper reversing part 3 for receiving one side 101 of the paper with a curved inner peripheral face 31 and reversing the paper while curving it along the curved inner peripheral face; and a second carrying part 4 for receiving one side 101 of the reversed paper with a carrying face 41 and carrying the paper to the second direction (an arrowmark T). The first carrying part 2 and the second carrying part 4 each carry the paper while sucking it to the carrying face. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a new sheet printer which can apply especially corona treatment to a print sheet to be printed in an in-line mode within the sheet printer or in an in-line mode to a printing process, right before actually printing the print sheet. SOLUTION: A sheet supply device is constituted as a single sheet feeder (10) which can convey print sheets without being piled up in the region of a conveyance stand (16) by dealing with the print sheets lifted up from the a stack of the print sheets (11) to be fed one by one. In addition, in the region of the conveyance stand (16) equipped with at least two conveyance systems (17 and 18), a plurality of corona treaters (21, 22 and 23) which apply corona treatment to the entire surface of the print sheet, are provided. Further, on the downstream side of the conveyance stand (16), a stream feeder (24) for creating a sheet flow of the print sheets partially piled up over each other, from the print sheets conveyed without being piled up in the region of the conveyance stand (16), is arranged. The print sheets are supplied to the printer or a varnishing device as the flow of the piled sheets slipped out of place, through a sheet placing stand (26) arranged on the downstream side of the stream feeder (24).
