Meandering Glue Application on Cardboard Boxes
Cardboard boxes are charged with static electricity by separation and friction when they are taken from a stack and transferred. Glue is also charged by friction and separation when it comes out from the nozzle.
In the process of applying glue onto cardboard boxes, the glue meanders due to the force of static electricity, resulting in application on unnecessary areas or improper box assembly.
