Self-Measuring Roll Goods

Editor, Nonwovens Industry

A manufactured roll goods product has been issued a patent. The material features a pliable substrate, a leading edge across the width of the roll, a side edge along the long dimension of the roll, a front surface and a rear surface with fiducial markings. The fiducial markings include an array of symbols, with at least a portion of peripheral edges of the symbols being spaced apart from peripheral edges of adjacent symbols. A pitch of the array defines a gross measurement scale. The fiducial markings are substantially free of grid lines. The symbols include a circle with a diameter corresponding to the gross measurement scale and a polygon within the circle. The polygon is concentric with the circle and has a height equal to one third the diameter of the circle.
