A rotatable roller is provided which includes a first end and a second end and a surface adapted to wrap a portion of the media thereupon. A carriage conveys the roller along a path. The roller is moved by first and second drives. The first and second drives can be differentially operated to reorient the roller with respect to a direction along the path. The first drive and the second drive can be operated, differentially or non-differentially, to move the carriage along the path. The reoriented roller can be rotated about its axis while conveying the media to wrap the portion of the media onto the surface. The portion of the media can be sized to wrap over the surface of the reoriented roller without overlapping itself. The first drive and the second drive can be operated non-differentially to convey the reoriented roller along a portion of the path.
