A steering guide laterally positions material running over rollers rotating in a roller carriage. The steering guide imparts angular displacement to a support platform positioned between a grooved inner track and a grooved outer track. The roller carriage, which may vary substantially is size and shape, is coupled with the support platform. The steering guide eliminates the need for a separate rack that supports the weight of the roller carriage. The steering guide thereby reduces complexity, cost, and spare part inventories, while simplifying assembly, installation, and maintenance. The steering guide also precisely locates the roller carriage with respect to a virtual center, thereby enhancing accurate steering of the web. In addition, the steering platform may be formed from strong but light aluminum, thereby reducing inertial forces that act when the steering guide moves the support platform.
