Automatic Layflat Calibration
Automatic Layflat Calibration (ALC) is a new feature for the DRJ IBC Control System and nonIBC Width Controller that utilizes a flat width measurement device placed near the winder to automatically calibrate and compensate for film stretch and shrink as it makes its way down the tower. A host of factors cause varying degrees of stretch and shrink which effect the width as it is wound: utilizing ALC is the next step in providing customers with ultra-precise layflat tolerances, simplifying width management operations via automation and improving user safety.
For production where job orders change often, ALC speeds up job change time, and improves long term accuracy.
Larger Touch Screens for DRJ Systems

IBC control systems and nonIBC width control systems will be shipping standard with a larger HMI touch screens. IBC standard will now be 7.5 in. (190mm), and LF-Sizer 6 in. (152mm) for better visibility.
Neck Height Control for HDPE/MDPE High Stalk Bubbles
Neck height variance on high stalk bubbles correlates to a variance in dart impact properties. As process conditions (such as ambient temperature) change, so too will the neck height resulting in off spec dart impact and layflat. DRJ has solved the issue of drifting neck height with the new Neck Height Control feature available to integrate with DRJ width control systems. An ultrasonic sensor is integrated that faces the bottom of the bubble flare to measure neck height, then maintains neck height by automatically regulating airring blower speed.
Seal-Cut Fault Diagnostics Features
Troubleshooting fault issues related to DRJ's machine direction sealing solution has become easier: a new firmware update now includes a fault detection feature which points users to the physical location of the fault and potential issues causing the fault for easy detection and resolution.
