  • Patent number: 7506542
    Abstract: A device for measuring the tack of materials, comprising a first cylinder (1) included in a fixed frame (2) and a second cylinder (3) included in a movable yoke (4), whose outer surfaces contact each other via a layer of the material to be tested for tack (8). The yoke (4) is connected with the frame (2) via a connecting element (5) movable about a center. A force sensor (6) is included between the yoke and the movable connecting element or between the frame and the movable connecting element. The output of the force sensor (6) is connected with processing means (7) for processing the measuring signal delivered by the force sensor into a material-specific tack value. In a first calibration step, the first cylinder is coupled with a static mass (11) via coupling means (10). A first correction value, based on the measuring signal delivered by the force sensor, is stored in the processing means.
