Short Answer
Center guiding maintains web centerline by detecting both edges and calculating average position.
Center guiding is a web handling technique that maintains the centerline of a moving web by detecting both edges simultaneously and calculating the average position. Unlike single-edge guiding, center guiding systems use two sensors (or one wide sensor that sees both edges) to compute the true centerline regardless of web width variations. This approach naturally filters out edge defects and wrinkles, providing more stable control than single-edge systems.
