ABSTRACT:
Methods and apparatus for transporting a sheet first toward and then along a registration edge provide a support for the sheet having a sheet support surface adjacent the registration edge and a first drive wheel rotatable about a first axis for driving the sheet on the support surface. A second drive wheel rotatable about a second axis extending at right angles to the support surface is provided at the first drive wheel. Such first wheel is initially positioned at an angle to the registration edge and is rotated with the second wheel through a third wheel about the first axis, with the sheet being brought into peripheral engagement with the first drive wheel to transport the sheet on its support surface to the registration edge. The third wheel with the first wheel is then swiveled about the second axis and about the second wheel, toward parallel relationship with the registration edge. The swiveled first wheel is then further rotated with the second wheel through the third wheel about the first axis to transport the sheet along the registration edge. In practice, the third wheel with the first wheel may be laterally moved relative to the second wheel equidistantly about the second axis to swing the first wheel toward parallel relationship with the registration edge.
