  • Patent number: 5201400
    Abstract: An apparatus for conveying a roll such as a paper web roll set on the roll stand of a corrugator to a predetermined location at low speed, with a small initial force and without scratches or other damage to the roll. The apparatus includes a plurality of flat plate-shaped bases arranged end-to-end in the direction in which the roll is conveyed, a plurality of fulcrum shafts each passing through shaft holes in a corresponding base to allow each base to pivot on its shaft, raising and lowering units beneath each base to raise and lower the base, a load sensing unit below the downstream side of each base to detect a load exerted on the base, and a controller responsive to a signal from the load sensing unit to control raising and lowering units at a subsequent stage. When the bases are assembled together with the fulcrum shafts, a conveyance path for conveying the roll to the predetermined final location at low speed and without any acceleration is formed.
