If the internal curve is large (say greater than 300mm radius) then it is not necessary to
slow the feed on bump bar particularly so a speed of say 3500 to 4500 is common.
If the internal curve is tighter such as the small radius internal as shown in figures 3 and 4,
then a slower speed will be necessary to ensure the band sits tightly in the small radius.
In this situation a bump bar speed of say 2000 may be appropriate.
The hold count needs to be set so that this speed is maintained through the laying of tape
and maybe also controlling the trimmer speed.
9.4.3.2 Aggregate (920) retracted by bump bar.
In certain situations it may be desirable to have the glue station (920) (aggregate) retract
fully rather than just float on the bump bar.
For example in some wireways, it might be desirable to prevent the glue station from
pressing against the panel. There is a small deflector bar (918) but in any event, if it is
preferred, it is possible to force the glue unit back on the bump bar by activating the
setting: Retract on Bump bar (971). Refer 9.3.6 Advanced Controls: Panel Shapes
In this situation, when the bump bar (915) is touched, instead of just floating, the glue unit
will swing back until it touches the sensor (935) on the glue station (920) retract cylinder.
When the glue unit reaches this sensor (935), it will float until the setting Hold Count Bump
Bar counts out and then swing forward naturally.
It is possible to adjust the position of the sensor (917) by releasing the screw in its
supporting collar and sliding the collar along the air cylinder.
It must be noted that usually however, this use of the Retract on Bump Bar setting is
unnecessary as the glue unit will naturally float along the panel edge.
