Tension in continuous webs, particularly webs that are in motion (3) is measured by bringing an elastic sensor in contact with the paper web (3) and the displacement of an elastic sensor (4) relative to a fixed point of reference (10) is measured, the displacment being a measure of the web tension. An apparatus for the measurement of the web tension comprises a measuring head (1) equipped with at least one smooth surface of contact (2), and an elastic sensor (4) fastened to a head (1) and movable relative to the head, extending through an imagined plane touching a contact area (2) and a device (10) for the determination of the position of the elastic sensor (4). |
