The number one issue which results in poor edgeband quality is
chipped edges at the banding/panel interface.
A major cause of rejected panels is chipped edges on the
surface of TFL (melamine) or HPL panels. Chipping on the
top and bottom cut on a saw is normally from a bad main blade.
Chipping on the bottom only cut on a saw is usually due to a
bad, misaligned or missing scoring blade. On a nesting router,
nesting router bits can sometimes fracture the edge, so when
edgebanded, the pressure rollers that close the top/bottom of
the banded edge will pop the chip loose.
An edgebander with pre-mill can all but eliminate chipped
edges due to panel sizing or nesting. It can also remove a score
line that was set too deep. If your edgebander has pre-mill and
you still have chipping, inspect the pre-mill cutters for glue and
resin buildup as well as chipping or excessive wear. If you are
not using diamond tooling in the pre-mill you should invest in
it. Carbide cutters can wear out in a short time, especially at the
Another possible cause for chipping is misalignment of the
panel edge and the application roller. If the angle is severe
enough, the glue roller contacting only the upper or lower
edge can cause chipping. The easiest way to check verticality
of the glue application roller is to: build up a panel to near the
maximum thickness accepted by the edgebander; trim the edge
and verify it is perpendicular or use the pre-mill; run the panel
through with only glue applied to the edge - no banding; check
for an even spread of glue from bottom to top of the panel.
