  • Apparatus and a method for rolling compressible sheet material
    Publication number: 20020066376
    Abstract: A tucking bar for directing sheet material between a drive roller and a mandrel of a roll-up machine comprises an elongated member having opposing ends that are supported by an arm. The arm is adapted to pivot about an axis that is substantially parallel to an axis of rotation of the drive roller to move the elongated member along an arcuate path about the drive roller. A roll-up machine comprises a drive roller supported by a frame and a mandrel supported adjacent the drive roller. A tucking bar supported by a forward end of the frame is provided for tucking the sheet material between the drive roller and the mandrel. A method for rolling sheet material includes the steps of displacing the tucking bar to direct sheet material between a drive roller and a mandrel and rolling the sheet material on the mandrel.
