AF3 WebFlagger
AF3 WebFlagger Safely and accurately flags webs moving at speeds up to 4,000 fpm
The age-old need for reliable defect marking has never been addressed until now. For the first time a flagger has been engineered from the ground up specifically for high speed web applications. Others have tried modifying label applicators but this approach has never succeeded. You can eliminate all the concerns for employee safety with our Web Flagger.
AF3 Features
- Safely and Automatically Flags Defects
- Flags at Speeds Over 4,000 Feet/Minute
- Accurately and Reliably Applies Flags
- Connects to All Inspection Systems
- Tracks Defects From Upstream Locations
What Makes it Different?
The AF3 WebFlagger has become an industry standard in defect marking. 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.
ScrapTracker
ScrapTracker software is used to log various causes and amounts of defective material, along with numerous process parameters. This data is used to generate reports for tabulating efficiency as well as making correlations between process conditions and defects. ScrapTracker can operate independently or in conjunction with the defect tracking system.
What makes it different?
ScrapTracker is a system which creates a data file or “roll map” associated with each roll of material manufactured, processed or printed. The data file contains all the information about the locations and types of any defects within the roll. ScrapTracker uses the AF3 WebFlagger to apply flags with unique ID numbers. The flags are pre-printed with a unique number and a corresponding bar code. A flag can be triggered by an operator pushbutton or a signal from the machine. When a flag is signaled to be applied, the flag’s ID number is recorded along with the type of defect and its location within the roll. Six different types of defect can be logged.
ScrapTracker creates a roll map for each roll produced in the form of a data file. This data file can be printed as a report or uploaded to plant LAN or any data storage device. The roll report created can be used in the subsequent process to help identify the type of defect to be inspected and/or removed. If the downstream process is equipped with our RollCode system, the roll map data is used to automatically stop the machine at each flagged location. The data in the roll map can also be used to create custom reports for scrap. Reports such as total amounts of scrap, scrap by machine, shift, month, etc. can be generated. These reports allow a quality control department easy access to this valuable data used for process improvement and scrap reduction programs.
