Benefits of Measuring Your Hot Melt Coating Thickness Cross Direction Web Profile

Speeding up the start-up process, reducing scrap and rejected material, archiving data against claims and improving QC/QA are among the many benefits of measuring your hot melt thickness web profile with a NIR Transmitter and Guardian Scanning Profile System.

Whether you operate doctor blades, die bolts or other hot melt applicators, a uniform web profile is important to you and your customers.  Often times the system is started up and stopped while a sample is sent to the lab for analysis.  After receiving the results, the applicator is adjusted and started up only to be stopped for another sample and analysis to confirm correction.  Sometimes the adjustment over compensates and the process repeats itself.  With a web profiler, the machine can be adjusted while running and the results immediately seen on the hot melt profile display.  A trend chart and plot below illustrates the hot melt process in adjusting the applicator to meet a 1.4 mils target set point.  Red is alarm out of specification, yellow is alert getting out of specification and green is good at a set point of 1.4 +/- 0.1 mils hot melt thickness.
