Inspecting and setting
Edgebander
G 500
8.8.1 Function
The edge scraping unit allows to take off a thin layer of
edge, rectifying the profile made by the flush trim cutters.
When the panel feeds through and reaches the scraping
unit it is copied by the feelers (copiers).
The edge scraping unit glides along the workpiece and
the edge material. The fixed knive lifts excess from the
edge, thus leaving a completely smooth edge surface.
Fig. 33: Function
The upper edge scraping unit regulates itself automati-
cally when the tool thickness is changed, because it is
attached to a pressure bar. According to the edge scra-
ping knife and the adjustment of the feeler it is possible
to create different edge scraping profiles (2 or 3mm
radius). At the end of the cycle, the chip breaker spring
causes chips to be separated; this procedure is necessa-
ry in order to prevent chips from becoming entangled in
the buffing unit.
To exclude the lower and upper edge scrapers, pull ball
handle 4, thus moving the unit away from the workpiece.
