5.5 Radius Scraper station RB-8:
The scraper is used for removing the small undulations that the trimmer cutters may
leave on the PVC edging band, providing an even finish. Its operation is very similar to that of
the trimmer, in that it has horizontal and vertical tracers, the only difference being that it works
the band with a blade rather than a motor with its cutter.
SCRAPER ADJUSTMENT: First select the station, checking that it is not locked by the
locking knob. Pass a panel through to check that the station makes the tracing movements both
vertically and horizontally. This tracing must not be greater than 2mm.
The horizontal tracer has to be moved to obtain the required radius. Moving this tracer
forward means the blade scrapes less, while moving it back scrapes more. First slacken the
fixing lever on the horizontal tracer, then turn the tracer regulating knob clockwise to move the
tracer back, or anti-clockwise to move it forwards. If horizontal tracing is lost or excessive it must
be adjusted using the tracer dead stop.
When the radius is as required, all that is needed is to adjust the top of the radius via the
knob that regulates blade lifting and lowering, as in this case the vertical tracer is fixed. For the
top scraper, turning clockwise lifts the blade and it scrapes less. Conversely, turning anti-
clockwise lowers the blade so that it scrapes more. At the bottom the reverse is true, in that
clockwise turning to lift the blade scrapes more, while anti-clockwise turning lowers it and it
scrapes less.
