SHEET AFFIXING APPARATUS
A sheet affixing apparatus includes a drawing unit for drawing a sheet from a sheet roll and a sheet cutter for cutting the sheet drawn from the sheet roll by the drawing unit. The sheet cutter includes a sheet support for supporting from below the sheet drawn from the sheet roll by the drawing unit, a cutting knife for cutting the sheet supported by the sheet support, along the sheet support, and a sheet presser for pressing the sheet against the sheet support forwardly of the cutting knife in a direction along which the cutting knife moves in cutting the sheet, when the sheet is cut.
Sheet-feeding system and sheet-feeding method
A sheet-feeding system includes a holding part which holds an end portion of a sheet, a nozzle part for discharging an adhesive agent for joining sheets to each other, and a nozzle moving unit which supports the nozzle part such that the nozzle part is made movable within a region including both temporarily holding parts, in which when a sheet joining condition is established where a remaining amount of the sheet on one original sheet roll becomes equal to or below a predetermined remaining amount, an end portion of the sheet on the other original sheet roll is conveyed to the temporarily holding part by the holding part and, thereafter, the nozzle part is moved to the temporarily holding part, and the adhesive agent is discharged to the end portion of the sheet from the nozzle part.
HANDLING DEVICE AND METHOD FOR HANDLING WEB-SHAPED PACKAGING MATERIAL
A handling device having a holder for gripping web-shaped packaging material, which holder has a curvature in the longitudinal direction of the holder. When the packaging material is gripped by the handling device, a free end section of the packaging material is arched in the transverse direction of the packaging material and projects out from the handling device to be inserted into a processing station of a packaging machine.
Sheet-feeding system and sheet-feeding method
When a remaining amount of a sheet on one original sheet roll is equal to or less than a predetermined remaining amount, a pair of holding pads is brought into a first posture where holding surfaces are opened, and the holding surface of one holding pad is pressed to a joining end portion from the outside of the original sheet roll in a radial direction of another original sheet roll. Further, the holding pad is moved such that the joining end portion is separated toward the outside of the original sheet roll in the radial direction. Further, the posture of the pair of holding pads is changed into a second posture where the holding surfaces approach each other, and the joining end portion is conveyed to a joining part in a state where the joining end portion is sandwiched between the holding surfaces of the pair of holding pads.
SUCTION BRAKE, SHEET CONVEYOR WITH SUCH SUCTION BRAKE AND METHOD OF APPLYING A RETARDATION FORCE TO A MOVING SHEET OF MATERIAL
The invention relates to a suction brake for use with a sheet conveyor configured to convey a succession of flat elements in sheet form along a conveying path between a first location and a second location, the suction brake comprising: a hollow body having an interior cavity and a face that defines a plurality of suction apertures that communicate with the interior cavity; an obturator arrangement coupled to the hollow body and moveable with respect to the suction apertures; the obturator arrangement being moveable between an open position, in which the obturator arrangement exposes the suction apertures to a maximum extent, and a restricted position, in which the obturator arrangement occludes the suction apertures to a maximum extent. The obturator may rotate or be linearly translated in moving between the open and restricted positions.
MEDIUM CONVEYING DEVICE AND INKJET PRINTER
Provided are a medium conveying device and an inkjet printer that can convey a medium stably. In a case where a paper P is conveyed along a plane in a conveying unit 40, a posture of the paper P is corrected by a posture correction unit 20, and then the paper P is delivered to the conveying unit 40 by a delivery unit 30. The delivery unit 30 holds a leading end portion of the paper P of which the posture is corrected by the posture correction unit 2 with a paper holding bar 31, and delivers the paper P to the conveying unit 40 by moving the paper holding bar 31 linearly along a conveying direction of the paper P by the conveying unit 40.
Arrangement and method for handling paper elements
An arrangement (100) for handling flat elements (202), in particular paper elements (202). A guiding structure (101) is provided, along which a flat element (202) is guidable and transportable along a transport direction (T). A hold-down element (102) is coupled to the guiding structure (101) for holding down the flat element (202) to the guiding structure (101). The hold-down element (102) has a support section (103) on which the flat element (202) is supportable. The hold-down element (102) extends along an extending direction (116) having a component perpendicular to the transport direction (T), wherein suction holes (104) are arranged along the extending direction (116). A suction unit (110) includes a suction opening (111) coupled to the suction holes (104) of the hold-down element (102), an air inlet (112) and an air outlet (113), wherein the suction unit (110) directs air from the air inlet (112) to the air outlet (113) for generating an air flow (114). The suction opening (111) is formed and arranged such that the air flow (114) passes the suction opening (111) so that air flow (114) entrains air through the suction opening (111).
SHEET-FEEDING SYSTEM AND SHEET-FEEDING METHOD
