These are the narrow, durable tapes and belts used to thread and guide the continuous sheet of paper through the various cylinders, dryers, and folders of a web press. They physically support the paper ribbon and help it navigate complex paths without tearing or losing tension. Operators must carefully route the paper along this path during setup or after a break.
