ABSTRACT:
A take-up roller for winding a continuous recording medium has an outer hollow cylindrical tube with a longitudinal slot and an inner hollow cylindrical tube with a longitudinal slot. The inner hollow cylindrical tube is mounted concentrically within the outer hollow cylindrical tube. Two eccentrically mounted weights are fastened on opposite sides of the inner tube slot, keeping the inner tube oriented with its slot facing downward. The outer tube is driven by a drive motor to rotate the outer tube relative to the inner tube until a sensor signals the drive motor to stop upon the alignment of the tube slots. A leading edge of the recording medium is inserted into the center of the inner tube though an opening formed by the alignment of the slots. Then, the outer tube is rotated relative to the inner tube, thereby closing the opening and wrapping the recording medium around the edge of the outer tube slot. A friction force is created between the tubes, due to the presence of the media between the tube slot edges, causing the inner tube to rotate with the outer tube. A one-way roller clutch system connects the tubes and prevents any relative rotation between the tubes to maintain the opening in its closed position during winding.
