Case packing and sealing in packaging lines depends on several components to run steadily and reliably. In order for a system to run continuously at all times, each piece of equipment needs to be concisely installed. The usual suspects of precision engineering on your case sealer adhesive systems are the pump, applicators and nozzles. Most line operators undervalue the importance of heated hose length in the overall operation and efficiency of the line.

Heated adhesive hoses get attached to the hot melt tank and run from the tank to the application gun, which is mounted on the packaging line itself. Heated hoses are typically attached to the tank with a straight connector, but can have both a 45 degree or 90 degree connection option, depending on where the tank is placed on the line. The applicator plug at the end of the hose is also sent out as a straight connection, but can be switched to a 90 degree plug if needed. There are typically two – four hoses used on each packaging line. With a two hose line, one hose will run up the line, across the top and down to the applicators. This hose transfers the adhesive that will seal the top of the carton and is mounted using straps. The second hose will typically run straight along the side of the packaging line to seal the bottom of the case.  No matter how many hoses you run or how you mount them, it is very important to have the correct length hose.

Our technicians visit several packaging facilities each year, and their biggest take away is that most purchasing agents are ordering the wrong length hose. Typically, the hoses that we see are too long. They are either running extra length on the ground, which is a safety hazard, or there is excess hanging before the applicator connection, which can cause heating inconsistency issues. It is important to measure from the tank through the entire hose travel process, including mounting straps, before ordering. Universal Systems SE manufactures our ClearFlow™ line of heated hoses in 2 ft increments. So, if you measure 6 ft, order a 6 ft hose and if you measure 7 ft, order an 8ft hose. Make sure that you measure precisely! If need a hose longer than 24 ft, we can custom make you any length up to 50 ft.
