  • Patent number: 4793392
    Abstract: A bending device for curving sheet-like members, comprising a row of double roller clamp means, each having a pair of parallel rollers adapted to receive and clamp the sheet-like member therebetween. Hinge means are located between each adjacent pair of clamp means for hingeably coupling each clamp means to an adjacent clamp means. Actuating means are provided, connected between each adjacent pair of clamp means, which are operable to cause pivoting of the double roller clamp means about the hinge means, thereby curving the row of clamp means, and accordingly the sheet-like member clampingly held by each of the clamp means. In a preferred embodiment, the clamp means are laterally displaceable along the hinge means relative to an adjacent clamp means, to allow alignment of the clamp means along a diagonal.
