  • Patent number: 8474807
    Abstract: A conveying device that conveys a sheet bundle with a flattened back-face portion includes a first conveying unit, a driving unit, and a second conveying unit. The first conveying unit retracts to a position where no driving force is exerted on the sheet bundle before a leading end of the sheet bundle formed in a flat spine shape enters, and abuts on the sheet bundle to exert conveying force after the leading end of the sheet bundle passes a conveying position. The driving unit moves the first conveying unit to retract to the position and to abut on the sheet bundle. The second conveying unit is positioned on an upstream side of the first conveying unit in a sheet bundle conveying direction and conveys the sheet bundle towards the first conveying unit.

  • Patent number: 8243324
    Abstract: When a user sets, from a user interface window using a bookbinding application, instructions of dividing a document into a plurality of parts and stapling each part of the document, a printer driver generates one job in which the staple attribute of a binder corresponding to each part is set to “ON” or “OFF”, and issues the job for a printer. With this operation, the user can perform staple designation to an arbitrary part of the document, and can realize a plurality of staple processes in one print job.

  • Patent number: 4506873
    Abstract: A higher speed paper sheet product cross or quarter folding system is afforded for use with high speed paper product transport conveyors such as used with web printing presses, and the like producing signatures. The higher speed is obtained by novel braking means for gradually slowing down the paper product, non-linearly, as it enters the folding station, thereby preventing damage to the product or erratic folding caused by high speed impact with the fixed stop in the folder that has previously prevented the system from running at the higher speeds that can now be obtained by this improved system. Moving slow down stops are carried by a cyclically moving timing belt to intercept a paper product moved thereinto at higher speed by a conveyor. This moving stop is synchronously timed to intercept the paper product moving at a highest transit speed and is non-linearly moved to slow the paper product down to a lowest speed before it engages the fixed stop for folding.
