Up
When the derailed
sheet in up, the
rail is continuous
and the disjoining
device is closed.
Sheet
insertion
Rolling up, the
derailed sheet
lifts the disjoining
device and
re-enters the rail.
Down
When the sheet
descends
inside the rail, the
disjoining device
drops down.
Automated operation
With this operation, if the
sheet comes out of the
guide it gets back inside by
raising the disjoining device;
once the sheet is rolled up
the disjoining device drops,
so that the guide is once
again solid without gaps.
