  • Patent number: 4946212
    Abstract: A lifting device is employed to support a roll of paper wrapped around a core, the lifting device including a flat support plate having, in its central portion, a single upstanding loop or link welded by one side to the plate. A shallow cup-shaped core cap or sleeve with an open central portion fits over and surrounds the loop so that a portion of the other side of the loop protrudes through the central portion of the cup. The ends of the loop are spaced inwardly from the sides of the cup. A continuous woven fabric or strap, formed with overlapping end portions, is received under the outer side of the loop, the overlapping end portions forming a lower bight, received between the loop and the inner perimetrical edge of the cup. The cup fits into the end of the core and the sling extends up through the hollow core so that its outer end portion protrudes outwardly of the upper end of the core for being received on a cargo hook.
