  • Patent number: 6059705
    Abstract: A paperboard blank processing apparatus including a rotatably mounted processing head for operating upon successive paperboard blanks is disclosed. A paperboard blank registration sensor is provided upstream from the processing head for detecting a preprinted registration mark on a surface of an approaching paperboard blank. A controller is responsive to the registration sensor for determining whether the approaching paperboard blank is in proper registration with the rotary processing head. A registration correction window is defined by the controller and includes upper and lower limits defining upper and lower maximum correction values for bringing the angular position of the processing head into proper register with the linear position of the approaching paperboard blank. The controller further defines an averaging window containing the registration correction window wherein the registration correction window may be shifted within the averaging window in response to consistent registration errors.

  • Patent number: 5950404
    Abstract: An apparatus for packing articles contains successively in a conveying direction a feed station, where the articles to be packed are fed into the installation, a station for opening the pack and a station for sealing the filled pack. The two stations, optionally also a compressing station, are successively located on rails, to which they can be fixed in random positions. Consequently it is possible to modify the mutual spacings of the stations and the absolute positions of the stations. This makes it possible to adapt the apparatus to different pack sizes, different articles to be packed and further differing circumstances, whilst still allowing short conveying paths.

  • Patent number: 5944645
    Abstract: A finisher includes moving devices, which are movably mounted relative to a conveying path for applying additional-workings to a sheet having an image formed surface, such as a folding stopper which adjusts the position for folding the sheet, an aligning device which aligns the edge of sheet being temporarily stacked, and a head unit of a stapler which staples the sheet at a proper position. The finisher retracts or returns the moving devices to their relevant home positions, which are separated by prescribed distances from the conveying path when a jam of a sheet occurs. Accordingly, the finisher forms a space which accepts a user's hand in the neighborhood of the stuck sheet, improves the operational efficiency of removing the sheet, and prevents the user from touching the moving devices and inevitably moving them to abnormal positions.
