20080224389 | Sheet abnormality detection apparatus and method - A sheet abnormality detection apparatus includes a plurality of abutting members which move upon coming into contact with at least one of sheets conveyed to overlap while being shifted from each other in a convey direction and an object attached to a sheet. The plurality of abutting members are disposed side by side in a direction perpendicular to a sheet convey direction. The apparatus also includes an abnormality detection unit which detects a sheet abnormality on the basis of a relative positional shift among the plurality of abutting members. A sheet abnormality detection method is also disclosed. | 09-18-2008 |
20080229949 | Liquid transfer apparatus - A liquid transfer apparatus includes a supply cylinder and viscosity reducing agent supply unit. The supply cylinder comes into contact with a transfer target body and supplies a transfer liquid to the transfer target body. The viscosity reducing agent supply unit supplies a viscosity reducing agent which reduces a viscosity of the transfer liquid to the supply cylinder after the apparatus emergently stops and before the supply cylinder starts transfer. | 09-25-2008 |
20080229952 | Cleaning apparatus - A cleaning apparatus includes a first liquid supply unit, second cylinder, cleaning unit, third cylinder, second liquid supply unit, first cleaning liquid supply unit, and controller. The first liquid supply unit supplies a transfer liquid to a first cylinder. The second cylinder performs transfer to one surface of a transfer target body with the transfer liquid transferred from the first cylinder. The cleaning unit cleans the circumferential surface of the second cylinder in contact with it. The third cylinder is arranged to oppose the second cylinder and performs transfer to the other surface of the transfer target body. The second liquid supply unit supplies the transfer liquid to the third cylinder. The first cleaning liquid supply unit supplies a cleaning liquid to at least one of the first cylinder and the third cylinder. The controller controls the control unit to clean the second cylinder while the second cylinder is in contact with the first cylinder and the third cylinder. | 09-25-2008 |
20080229953 | Cleaning apparatus - A cleaning apparatus includes a cleaning web, contact member, and web travel unit. The cleaning web is supported to be able to come into contact with and separate from a rotating body so as to clean the rotating body. The contact member comes into contact with the cleaning web. The web travel unit causes the cleaning web to travel and causes the cleaning web to travel for a predetermined length after cleaning the rotating body. | 09-25-2008 |
20080229954 | Cleaning apparatus - A cleaning apparatus includes a liquid supply device and cleaning unit. The liquid supply device supplies a transfer liquid to a first cylinder. The transfer liquid supplied from the liquid supply device to the first cylinder is transferred to a transfer target body which comes into contact with the first cylinder. The cleaning unit comes into contact with and cleans the first cylinder. The cleaning unit is arranged downstream of a contact position where the first cylinder is in contact with the transfer target body in a rotational direction of the first cylinder, and upstream of a liquid receiving position where the first cylinder receives a liquid supplied from the liquid supply device in a rotational direction of the first cylinder. | 09-25-2008 |
20090008853 | Sheet processing apparatus - A sheet processing apparatus includes a first cylinder, second cylinder, third cylinder, first driving device, second driving device, third driving device, gap amount input device, and controller. The first cylinder receives a sheet from an upstream transport cylinder and holds the sheet. The second cylinder is disposed to oppose the first cylinder and prints/coats the sheet held by the first cylinder. The third cylinder is disposed to oppose the first cylinder and supplies ink/varnish to a circumferential surface of the first cylinder. The first driving device adjusts a gap amount between the first cylinder and upstream transport cylinder. The second driving device adjusts the position of the second cylinder with respect to the first cylinder. The third driving device adjusts the position of the third cylinder with respect to the first cylinder. The gap amount input device inputs the gap amount between the first cylinder and upstream transport cylinder. The controller controls the first, second, and third driving devices on the basis of the gap amount input from the gap amount input device. | 01-08-2009 |
20090008854 | Sheet processing apparatus - A sheet processing apparatus includes a first cylinder, second cylinder, third cylinder, first driving device, second driving device, third driving device, thickness input device, and controller. The first cylinder receives a sheet from an upstream transport cylinder and holds the sheet. The second cylinder is disposed to oppose the first cylinder and prints/coats the sheet held by the first cylinder. The third cylinder is disposed to oppose the first cylinder and supplies ink/varnish to a circumferential surface of the first cylinder. The first driving device adjusts a gap amount between the first cylinder and the upstream transport cylinder. The second driving device adjusts the position of the second cylinder with respect to the first cylinder. The third driving device adjusts the position of the third cylinder with respect to the first cylinder. The thickness input device inputs the thickness of the sheet. The controller controls the first driving device, the second driving device, and the third driving device in accordance with the sheet thickness from the thickness input device. | 01-08-2009 |
20090008855 | Sheet processing apparatus - A sheet processing apparatus includes a first cylinder, second cylinder, third cylinder, first driving device, second driving device, third driving device, and controller. The first cylinder receives a sheet from an upstream transport cylinder and holds the sheet. The second cylinder is disposed to oppose the first cylinder and prints/coats the sheet held by the first cylinder. The third cylinder is disposed to oppose the first cylinder and supplies ink/varnish to a circumferential surface of the first cylinder. The first driving device adjusts a gap amount between the first cylinder and upstream transport cylinder. The second driving device adjusts the position of the second cylinder with respect to the first cylinder. The third driving device adjusts the position of the third cylinder with respect to the first cylinder. The controller controls the second and third driving devices when the first driving device adjusts the gap amount between the first cylinder and upstream transport cylinder. | 01-08-2009 |
