Note: it is possible to lift the top tape guide (908) by pulling up on the adjuster screw (909)
against the spring pressure without unwinding it to allow the tape to be feed in. This is
achieved by lifting the screw (909).
9.1.2 End trimming tape
When the band is slid into the guides, the adjuster (909) is wound down (anti-clockwise
when viewed from above) until a positive amount of spring pressure is applied to the top of
the tape to ensure that it always remains against the bottom guide and cannot float up and
down.
IMPORTANT !
This adjustment is important. If too tight, the tape will bind in the guide. If too
loose, the tape can ride up and down on the panel. This can especially cause
problems if the leading edge is not sitting on the correct line when laying onto the
panel. If this is so, it is likely the butt join sensor will not have an edge to reference
and the butt join will be of poor quality.
This adjustment can be easily checked by sliding the tape forwards and backwards in the
guide to ensure it is firm but not too tight.
Now the top roller guide (910) of the infeed guide requires setting.
Ensure the tape is sitting flat against the bottom guide track and then lower the top guide
pin/bearing onto the top of the tape.
IMPORTANT !
This guide is very important to ensure reliable feeding of the tape and also square
cut butt join. If this guide is set too high, the tape can ride up during the butt join
cut and when the end trim rises up it will make a secondary cut on an angle which
will result in a non parallel cut on the butt join.
