Abstract
In an apparatus and method for plotting on sheets of different widths, such as by cutting and/or printing, a tool support holding a plotting tool, such as a pen or knife blade, is spaced apart from a laterally-extending sheet-supporting surface and movable in the y-coordinate direction over the sheet-supporting surface for plotting on the sheet. A first drive roller defining an abrasive surface is rotatably mounted adjacent to the sheet-supporting surface for engaging a first marginal portion of the sheet and driving the sheet in the x-coordinate direction. A second rotatably-mounted drive roller is spaced laterally relative to the first drive roller, and defines an abrasive surface for engaging a second marginal portion of the sheet and further driving the sheet in the x-coordinate direction. A first drive motor is drivingly connected to the first drive roller for rotatably driving the first drive roller, and a second drive motor is drivingly connected to the second drive roller for rotatably driving the second drive roller. Both the second drive motor and second drive roller are laterally movable along an elongated track relative to the first drive roller, to thereby define any w…
