#1 QUESTION; What is the tightest INSIDE radius you can band with an nVision contour bander?


ANSWER: Tight radii (less than feed roller diameters) is possible, but it depends on a few easy adjustments. To achieve extremely tight inside radii with thin flexible edgeband tape - 0.5mm (.018”-.020”) - you must:

 With your SNX nVision G3 Bander:
  • Use the correct glue – with thin PVC banding you need to be using a low temperature EVA glue.  The bands shown here were done with Jowat – 282.20 at 125 degrees Celsius.
  • Use quality flexible edgebanding – having banding with less thickness variation from roll to roll and ensuring you’re using tape within its shelf life is critical.  The test depicted was done with Rehau edge banding.
  • The routed edge of your laminated panel needs to be cut perfectly square, no axis transition (witness) marks and it needs to be blown-out with dry shop air to eliminate any dust/particles.
  • The feed speed of the machines needs to be set a 4-5m/minute
  • Due to interference issues as the panel is guided through the machine, you’ll need to remove the top pressure wheel.
  • Make sure the pressure roller and guide shoes are free of glue.  We used XCEL-EDGE XE5 wipes to clean the machine prior to banding.
  • Process the part like any other, but with a slight hesitation in the inside corner.

Following the above, we can successfully achieve a ¼” inside radii! Such small radii may require practice with your operators. We recommend testing in advance of banding production parts.
