fAQs AF3 Web Flagger
A: Flagging a web is a common method used to identify areas within a wound roll after it has been printed, coated, laminated, etc. These areas are typically defective. An operator either places a pressure sensitive label on the moving web by hand, or inserts a slip of paper into a winding roll at the rewind. A portion protrudes from the edge of the web like a “flag” making it visible after rewinding the web.
A: What we call a WebFlagger is sometimes called other names within the industry. Those other names include: flagger, tabber, tagger, web-marker, tab or tag inserter, or defect-marker. Novation’s AF3 WebFlagger automatically applies a pressure sensitive label or “flag” to almost any type of web moving at virtually all process speeds.
A: Novation’s flags have the adhesive deadened on the portion which hangs off the web’s edge.
A: No. Our flags have a film lamination over the print for strength.
A: The AF3 WebFlagger is signaled to apply a flag from a pushbutton or machine signal and does not require an operator to have any body part near the moving web or rewind section of the line.
A: We offer an optional slide base on which the AF3 WebFlagger can be mounted. The slide base allows the WebFlagger to be easily adjusted from side-to side to line up to the edge of different width webs.
A: The AF3 WebFlagger can be triggered from an included pushbutton or additional, pushbuttons or machine signal. Five inputs are included for triggering a flag from different devices.
A: Yes. If an encoder is connected to the AF3 an input from upstream can be configured to wait to apply a flag until the web has traveled a preset distance. For example, a signal from an automatic unwind splice would prepare the WebFlagger to apply a flag, but it would wait until the unwind splice reached the WebFlagger to apply that flag.
A: All our products are manufactured in our plant in Bethlehem, PA USA and supported by our own in-house technical and engineering staff.
