Summary:A method of managing mechanical stress on a crack tip when separating a flexible glass ribbon includes directing the flexible glass ribbon to an edge trimming apparatus including a cutting device. The flexible glass ribbon includes a first broad surface and a second broad surface that extend laterally between a first edge and a second edge. The first edge of the flexible glass ribbon is separated as the flexible glass ribbon moves by the cutting device forming a continuous strip of edge trim connected to a central portion of the flexible glass ribbon at a crack tip. A width of a gap between the first edge and the central portion is detected using a gap measurement device. A signal is supplied to a controller indicative of the width of the gap. The width of the gap between the first edge and the central portion is adjusted based on the signal using a gap adjustment device.
