Battenfeld Gloucester Engineering Co. Inc. said its O-Frame Scanner uses a fixed beta gauge for noncontact measurement of multilayer film that is effective with all barrier resins, regardless of film temperature.
The O-Frame Scanner provides real-time control through Battenfeld Gloucester's Extol process controller.
It mounts between the oscillating haul-off and the secondary nip, measuring the collapsed lay-flat film.
The beta gauge is enclosed in the rectangular O-Frame, through which the film passes before separation.
The sensor scans both sides of the film and begins sending data after a 90-degree rotation of the haul-off.
The company said conventional fixed-gauge sensors need a complete 360-degree rotation of the oscillating unit before they can calculate thickness and transmit data, and that can take as long as 20 minutes.
The company in Gloucester, Mass., said the O-Frame Scanner can be piggybacked to different sensors such as infrared or nuclear sensors, which supply data on the thickness of barrier layers.
