  • Publication number: 20020060031
    Abstract: Machine equipment in a paper or board machine comprising at least one wear ledge for contact with a clothing, and a support body for the wear ledge and a device for mounting the wear ledge to its support body. In accordance with the invention, the mounting device has a locking bar arranged in a groove in the wear ledge, and a cavity is formed in the support body and contains a press bar. The support body defines a plurality of holes extending from the cavity and open toward the groove in the wear ledge. Connecting elements extend through the holes and are rigidly connected to the clamping bar and the press bar, and spring members in the cavity act between the press bar and an opposite support surface of the cavity to retain the wear ledge against the support body in a stable operating position. An expandable hose is arranged in the cavity so as, when activated, to press against the press bar so that the spring members are compressed and the wear ledge becomes free for pulling out along the locking bar.
