Adhesive lane thickness and moisture measurement across a paper or film web continues to increase with food and other packaging demands. Instead of coating an entire web for label stock, these applications only coat narrow lanes of adhesive spaced across the web.
Process Sensors has developed a system that is quickly becoming the industry standard for spaced lane adhesive thickness and substrate moisture measurement. The Guardian Lane Measurement System allows operators to monitor each adhesive lane across the web.
The Scanning Frame System automatically detects web edges and stores lane locations from the edge to make measurements. The Near Infrared (NIR) transmitter can measure the coating on the wet end at the 1.94µ water peak or on the dry end at the 2.34µ hydrocarbon peak. The unique elongated and rectangular angled viewing area for measurement insures accurate measurement on even very narrow stripe/lane widths.
This Lane Measurement Profile System reduces start up time and scrap. After start up, systems normally run through and process measurement is less needed unless in closed loop control. Many small to medium sized companies benefit from these reasonable priced measurement systems but find that after start up and achieving set point, operators don’t always pay attention to profile. To meet this need, many incorporate Stack Alarms that trigger when any zone goes out of specification to alarm and cause the operator to view the profile and take corrective action (clean or replace a valve, increase actuator pressure, change water disk speed, adjust skew on LAS, etc.).
Data and Roll Reports can be saved and archived for QC and QA needs.
