In this video, Erik Weber, Midwest representative for Mendota, Illinois-based Black Bros., talks about adhesive application rates using a Black Bros. 775 adhesive spreader.

Weber describes the process of determining gram weight and using the best substrate during the testing process, which Weber suggests doing at the beginning of the shift or when switching a substrate.  

Over the 12-minute video, Weber answers typical questions and concerns such as uneven glue application and testing from left to right, spotty and inconsistent adhesive coverage on the substrate, and using too much adhesive.

Weber ends the video with some final thoughts. "We recommend at Black Bros. to reach out to your adhesive supplier to determine the appropriate amount of gram weight or mills that they would recommend on your substrates," said Weber.  "Additionally talk to them about how that adhesive reacts inside the roll coater, temperatures, water ... all that plays a part in how you apply your adhesive so getting them involved as well in this conversation is vital to making sure that you put down the right amount of adhesive.

"We also recommend the frequency of doing this process that we just did – left, center, right – to make sure that your gram weights are accurate from morning to noon to night to a 24/7 process as frequently as possible to make sure you're monitoring. Finally, let that groove pattern do the work for you this specific groove pattern that we've designed in-house is designed for 10 grams per square foot we can also design and manufacture many different types of groove patterns to match the adhesive to match the substrate and to match down the amount of grams per square foot."
