Blown Film Rotary Scanning Frame

The Blown Film Rotary scanner is used to significantly improve the feedback time for the gauging system to generate a polar plot of the bubble profile. Without this scanner, the system must wait for the device being used to randomize profile variation (e.g. oscillating die or haul-off) to complete one rotation before an update can occur, which can take several minutes. However the rotary scanner (depending on bubble diameter) can make a complete scan per minute.
The rotary scanner is designed to be installed below the collapsers and above the frost line to insure the best possible quality of measurement. NDC Rotary Scanners are available in several diameters to match the needs of your blown film process.
