Novation’s AF3 WebFlagger automatically applies a pressure sensitive label or “flag” to almost any type of web moving at virtually all process speeds. The AF3 safely and accurately flags webs moving at speeds up to and above 4,000 fpm (1,200 mpm). The flags have the adhesive deadened on the portion which hangs off the web’s edge to prevent the exposed portion of the flag from sticking to machine parts such as idler rolls, or from folding back onto itself. The flags also have a film lamination for strength. A flag can be triggered to be applied by either an operator with the press of a button, or from almost any machine signal. There are five additional inputs which can be utilized for customer connections.
Machine functions such as unwind splices can be used to trigger the AF3 WebFlagger. The AF3 can also connect to virtually any inspection system. The AF3 can be configured to track any input from a pushbutton, machine signal or inspection system. When the WebFlagger is configured this way, upon receiving the signal from an upstream device, it will wait to apply a flag until the web has traveled a preset distance. That is, until the defect arrives at the location of the WebFlagger. If the process has a web width which varies, the AF3 WebFlagger can be mounted on an optional, adjustable slide base. This slide base allows the WebFlagger to be easily adjusted from side-to-side with a hand wheel, allowing it to be lined up to the edge of different width webs.
