6.0 Glue System
The VL-HP uses a pressurized glue tower to apply a bead of hot melt glue to the small carton
flap. The glue tank should never be filled more than about ¾ full with glue chips. It is generally
a good idea to add only the glue chips you expect to use that day to the glue tank each morning.
The glue operates at an elevated temperature typically over 230° F. This can cause burns. Only
employees instructed in the safe handling wearing appropriate equipment should perform the
following steps.
In order to fill the glue tank, the first step is to raise the safety valve lever (1) to the open position
(shown closed in Figure 6.0). The safety valve lever allows the hot pressurized air in the glue
tank to safely vent away. A metal plate (shown transparent for clarity) covers the red second
lever (2) which latches the glue pot lid. The cover makes it more difficult to accidentally open
the pot with pressure still on it. Next, lift the black handled lever (3) to open the glue pot lid
(shown already open).
It is very important to keep contaminants from entering and potentially clogging the glue tank
nozzles. Hot melt glue chips should be carefully stored in a clean sealed container and care
should be used to keep from accidentally letting dirt and all other foreign material from getting
into either the glue storage container or the glue tank itself.
Close the glue tank lid (3) and re-pressurize the glue tank by first moving the clamping lever (2)
back to its closed position. Ensure the clamp has drawn the lid fully closed. Only then lower the
safety valve lever (1) to the “operate” position.
