ABSTRACT:
A system of indicating towel roll depletion in rolled towel dispensers. The end of the towel roll is treated with two ink or dye stripes, one longer than the other. Due to capillary action, the stripes carry a short distance across the surface of the towel. When enough toweling is consumed to reach the longer stripe, a series of single coding marks appear along the edge of the towel, indicating that the roll has been reduced to stub size. As more toweling is used, the shorter mark is reached and a series of double coding marks appear along type edge of the towel. The double marks indicate that the end of the roll is imminent.
