Abstract: A sheet guide apparatus includes an impression cylinder having a gripper device for holding a thin sheet or a thick sheet and adapted to transport the thin sheet or the thick sheet, and an air blowing device comprising an air discharge duct and discharge nozzles for blowing air on the thin sheet or thick sheet being transported by the impression cylinder. The sheet guide apparatus comprises: a displacement gauge for detecting the distance to the thin sheet or thick sheet being transported by the impression cylinder; and a control device for controlling the air blowing device, based on the detection results of the displacement gauge, to adjust the flow rate of discharged air so that the distance between the thin sheet or thick sheet and the displacement gauge becomes a distance which prevents the unstable motion of the thin sheet or thick sheet.

Abstract: A sheet guide apparatus includes a transfer cylinder, first vane members, and a lateral air blowing guide. The transfer cylinder conveys a sheet. The first vane members are arranged at at least one end of the transfer cylinder and rotate together with the transfer cylinder to discharge air in a radial direction. The lateral air blowing guide is arranged close to the transfer cylinder and discharges air from the first vane members toward the sheet which is conveyed as the transfer cylinder rotates.

Abstract: A static eliminator, provided in a sheet-fed printing press for doing printing on a sheet of paper, and equipped with static electricity removing devices for removing static electricity building up in the sheet, comprises: electrostatic sensors for detecting the amount of static electricity of the sheet; a display/selector having a display section for indicating information to an operator, and a selection section for selecting whether control over the static electricity removing devices is exercised or not; and a control device for controlling the display/selector so as to indicate the information in the display section of the display/selector, and also controlling the static electricity removing devices, based on the information from the electrostatic sensors.

Abstract: A sheeter apparatus includes: a cutter cylinder for cutting a transported web into sheets in cooperation with a fixed knife; lower high-speed transportation belts for transporting a cut sheet; and a suction device for sucking the cut sheet from suction ports of a suction roller, which causes the lower high-speed transportation belts to travel, in such a manner that a surface of the sheet which is on the other side of the surface facing the cutter cylinder adheres to the outer peripheral surface of the suction roller.

Abstract: An air blowing device for a printing press includes a plate cylinder, blanket cylinder, impression cylinder, air blowing equipment, air suction equipment, and cover. The plate cylinder is rotatably supported. Ink from an inking device and dampening water from a dampening device are supplied to the outer surface of the plate cylinder. The blanket cylinder is rotatably supported in contact with the plate cylinder. The impression cylinder is rotatably supported in contact with the blanket cylinder and cooperates with the blanket cylinder to print on a printing target body under conveyance. The air blowing equipment discharges air from one end side toward the other end side of the blanket cylinder. The air suction equipment takes in air, discharged from the air blowing equipment, at the other end side of the blanket cylinder. The cover forms an air passage extending from the air blowing equipment to the air suction equipment in an axial direction of the blanket cylinder.

Abstract: An air flow adjusting apparatus includes first, second, and third air passages, and a flow adjusting plate. The first air passage is to be connected to a load. The second air passage is to be connected to an atmosphere. The third air passage is to be connected to an air source and branches to be connected to the first and second air passages. The flow adjusting plate opens/closes a first connecting portion between the first and third air passages and a second connecting portion between the second and third air passages in an interlocked manner. The flow adjusting plate opens/closes the first and second connecting portions with a sum of opening areas of the first and second connecting portions being always set constant.

Abstract: A sheet guide apparatus comprises gripper devices for holding and transporting a printed sheet, an impression cylinder and a transfer cylinder for holding and transporting the printed sheet received from the gripper device, and a first guide device for guiding the printed sheet being transported. A front end portion of the first guide device is located upstream, in the flow direction of the printed sheet, from a transfer position, where the printed sheet is transferred from the gripper device to the impression cylinder, and the front end portion of the first guide device is also located near the transfer position. Suction holes opening in a front end portion of a plate-shaped guide of the first guide device are provided for sucking air. The sheet guide apparatus suppresses fluttering or instability of the sheet.

Abstract: A suction apparatus for a printing press includes a plurality of suction ports and air shutter devices. The suction ports suck and hold an object used for a printing operation. The air shutter devices are provided to the suction ports on at least one end portion side not used for a suction operation of a small-size object. Each of the air shutter devices is constituted by a passage block having an air passage through which air for sucking an object passes, a magnetic member arranged around an air passage opening portion of the passage block, and a shutter member consisting of a magnetic material and movable between a closed position where the air passage opening portion of the passage block including the magnetic member is closed and an open position where the air passage is open, one of the magnetic member and the shutter member being magnetized.
