1. “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 5 minutes or more to melt the outside edges of the glue. Pull up on the stick and remove all of the glue in the pot and discard.
2. Maintain proper glue temperature during production per the manufacturer specifications.
3. Reduce the glue temperature if production will be halted for more than an hour. If glue sits in the pot at that 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 and reduce the edgebander’s performance.
4. Check glue pot shoe adjustment to confirm the panels are not touching the glue roller as this will generate excessive wear. This can be checked using 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.
5. Check for “gate grinding” as the gates should not be touching the glue roller. This 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-in. difference will suffice.
