<p>The disclosed system assists an operator in dealing with flaws encountered during the spreading of web material to be cut in accordance with a marker stored in a computer memory. Information representing the location of the flaw is processed by a computer in conjunction with the marker information to yield results visually displayed to the operator concerning the seriousness of the fault's location and corrective action to be taken if the flaw does fall at a troublesome spot. The flaw location representation may be made by manual measurements entered into the system by way of a keyboard or may be made semi-automatically through a two-dimensionally encoded pointer. The visual display may give the operator information concerning a patch or concerning stop and restart lines for making a splice or may display a portion of the marker in the vicinity of the flaw. The display may be digital or pictorial and, if pictorial, may be made on a display area separate from the material web or may be projected directly onto the material web.</p> |
