  • Aligning device
    Patent number: 6135446
    Abstract: The invention relates to an aligning device (10) for individual sheet (12) alignment. The alignment device (10) comprises a sensor device (22, 24, 26, 28), a delivery device (18), and a transport device (14) located downstream from the delivery device in the direction of conveyance of the sheet (12). In order to align the sheet (12) the sensor device (22, 24, 26, 28) detects the side end of the sheet so that its position can be determined in relation to a desired printing position. The transport device (14) holding the sheet (12) is shifted in relation to the direction (16) in which the sheet (12) is conveyed so that the sheet (12) can be moved into the desired printing position. Before the sheet (12) is aligned the delivery device (18), which feeds the sheet (12) to the transport device (14), is opened.
