An apparatus and method for measuring web alignment at a splice disposed between a trailing end of an expiring web and a leading end of a new web. The apparatus includes a speed monitor monitoring the moving webs. A splice sensor indicates the presence and absence of the splice while an edge sensor provides a signal indicating the position of the edge relative to a reference position. The edge signals are manipulated to provide a skew and offset value which provides a measurement of web alignment.
