Glue Pot Maintenance

We understand maintenance can be time consuming and inconvenient, but it can really pay great dividends on your quality, profit, and productivity if you take the time to maintain the glue application system.  The following are few ideas for you, your operators, and your service tech to consider:

-"Sticking" the glue pot can be done periodically on pots with a good non-stick coating by inserting a wooden stick in the main chamber of the glue pot at the end of a production run, while the glue is still melted.  After the glue has hardened in the pot, turn on the heating elements for a few minutes, just enough to melt the outside edges of the glue.  Pull up on the stick and remove all of the glue in the pot and discard.  Additional gentle scraping can be done, being careful  not to damage the non-stick coating and making sure that debris does not fall into the bottom chamber of the pot where it could impede flow to the main roller.

-Maintain proper glue temperature during production per the manufacturer specifications. 

-Reduce glue temperature if production will be halted for more than an hour!  This is the main reason glue pots get to the point where you need to send them to us for reconditioning.  If glue sits in the pot at production temperature without moving for too long, the fillers in the glue will start to oxidize, or burn, to the inside chamber of the glue pot.  This can be very difficult to remove, and reduces the performance of the edgebander.  You should occassionally check the calibration on your temperature controller, too.

-Check the shoe adjustment to confirm the panels are NOT TOUCHING the glue roller as this will generate excessive wear.  You could check this with a solid straight edge and small strip of scrap paper.  The straight edge should not touch the roller when placed on the shoe.  However, it should hold 1-2 thicknesses of scrap paper snug between the roller and straight edge.  

  The panels were touching here and wore a groove in this roller, requiring an expensive replacement.

-Check for "gate grinding" as the gates should not be touching the glue roller, which will wear out the gates and glue roller, requiring expensive replacement.  Make sure the "return" gate is not closer to the roller than the "application" gate as this will eliminate the gate from scraping glue off the roller and onto your production floor.  About 1/16" difference will suffice.

-If your glue applicator has lubrication requirements, be sure to periodically keep them greased.  Use high-temp rated grease!

-Keep the area and glue pot clean!  If you have a leak or spill, clean it up right away.
