In our daily lives, we are all under tremendous pressure - family, career, health, etc. But did you ever think about your cold adhesive system pressure? Have you noticed your glue patterns trailing off near the end? Or have you had trouble with getting enough adhesive out to adequately cover the surface of the product? Maybe you actually have too much glue being applied.

The pressure in a cold glue system starts with a good suction system. The suction line should be free of cracks, sharp bends or pinches in the hose. The suction tube should be shorter than 12 ft. (3.6 meters) and preferably less than a 6 foot (2 meter) height difference between the pump and the glue source. The pump should not be excessively stroking so that all of its effort is going into building line pressure for your system. If the above points are not being met, then it should be rebuilt. The next part of the system is the glue regulator. A glue regulator can only supply the pressure that the pump produces and regulate it down to the desired level. It can't create any additional pressure. Some glue regulators have an adjustable handle on top to adjust the glue pressure to the valves. Some use air to vary the glue pressure along with machine speed. With either system, the glue pressure should be smoothly adjustable up and down. If not, the regulator should be maintained.

When checking your pump and regulators, also inspect the high pressure in the machine. Like the suction line, they should be routed properly and free of any noticeable damage or sharp bends. These few pointers will help keep your glue system functioning well and your customers happy. Don't let pressure get to you.  Keep your pressurized glue system in good working order.
