  • Method and control device for determining a register error
    Patent number: 7162956
    Abstract: A method and control device for determining a register error, whereby at least one register mark is printed and at least one sensor records the register mark, whereby the sheet edge of the sheet is recorded by the sensor, and the register error is determined from the sensor data and the target data.
    Type: Grant

  • Device for detecting the location of an edge of a transparent material, web edge control and printing press
    Patent number: 6734449
    Abstract: The invention relates to a device for detecting the location of an edge (2) of a transparent, anisotropic material (3,3′) comprising at least one sensor (1) with a light source (4), two polarization filters (6,7) with transmission axes (8,9) meeting at a 90° angle as well as a light detector (10), whereby the light source (4) and one polarization filter (6) are located on one side of the edge (2) to be detected and the second polarization filter (7) and the light detector are located on the other side. This type of device is to be configured in such a way that it can be used for detecting material (3,3′) with optical axes (14) in various directions without requiring assembly. This is achieved by at least one of the sensors (1) being configured and/or adjustable so that various angles (32) between the transmission axis of the first polarization filter (6) and the optical axis (14) of the transparent, anisotropic material (3,3′) are possible.
