How to Adjust Edge Banding Pressure Bars182

Edge banding pressure bars are essential for ensuring a secure and durable bond between the edge banding and the substrate. By applying the correct amount of pressure, these bars prevent the edge banding from lifting or peeling away over time.

Adjusting the pressure bars on an edge banding machine is a critical step in the edge banding process. Proper adjustment will ensure that the edge banding is applied evenly and adheres firmly to the substrate. Incorrect adjustment can lead to a variety of problems, including bubbling, peeling, and delamination.

Here are the steps on how to adjust edge banding pressure bars:1. Position the workpiece correctly
* Place the workpiece on the edge banding machine table and align it with the fence.
* Make sure that the workpiece is flat and free of any debris.
2. Adjust the top pressure bar
* Loosen the lock nuts on the top pressure bar.
* Raise or lower the pressure bar until it is about 1/16 inch (1.5 mm) above the workpiece.
* Tighten the lock nuts to secure the pressure bar in place.
3. Adjust the bottom pressure bar
* Loosen the lock nuts on the bottom pressure bar.
* Raise or lower the pressure bar until it is just touching the workpiece.
* Tighten the lock nuts to secure the pressure bar in place.
4. Test the pressure
* Run a test piece of edge banding through the machine.
* Inspect the edge banding for any signs of bubbling, peeling, or delamination.
* If necessary, adjust the pressure bars accordingly.
5. Make final adjustments
* Once the pressure bars are properly adjusted, make any final adjustments to the machine settings, such as the feed speed and temperature.
* Run the edge banding machine to apply the edge banding to the workpiece.
Tips for adjusting edge banding pressure bars:
* Use a sharp edge banding knife to ensure a clean cut.
* Apply a thin layer of adhesive to the substrate before applying the edge banding.
* Allow the adhesive to dry for a few minutes before applying the pressure bars.
* Use a heat gun to soften the edge banding before applying the pressure bars.
* Inspect the edge banding frequently for any signs of problems.
By following these tips, you can ensure that your edge banding machine is properly adjusted and that your edge banding applications are secure and durable.
