8.7 Scraping system
The edge banding machine, scraping edge system is to eliminate due to trimming non linear
motion of the cutting caused by the traces, the sapwood on the lower part of the more
smooth and clean. In the actual production process, the following parts are likely to
be adjusted:
8.7.1 The regulation of the scraping system (Fig. 12):
（1） if you want to change the edge thickness greater than the thickness of the band
edge of the current device used, you need to first scraping amount regulating
handle (1 and 4) increase, so that the upper and lower scraping the right amount.
Then, the upper and lower circular arc regulating handles (2 and 5) are adjusted
to make the circular arc with a suitable edge. After adjustment, lock the handle.
Note, in the regulation, because the regulating handle is more sensitive, so
please do not substantially adjust the handle.
（2） if the replacement of edge thickness is less than the thickness of the band edge
of the current device used, you need to first scraping amount regulating handle
(1 and 4) small, make scraping the right amount. Then the upper and lower circular
