- The changing of the spool
diameter due to
the coils of tube makes
the speed vary during the
cycle. It is necessary to
compensate for the
variation. This is the role of
the turbine flap.
- During winding, the
hose retention bar follows
the PE tube. Its movement
is transmitted to the flap by
the cable.
