At maximum speed, the cleaned glass enters the positioning station, where the
longitudinal
and transverse sides of the panes are aligned with repeatable
accuracy according to their
respective geometry. The transfer unit,
equipped with impression-free suction cups, lifts the
positioned glass panes.
Non-occupied cups are closed automatically. The transfer unit transports
the
glass via precise linear guides to the assembly position.
From a choice
of up to 16 different PVB film coils, the suitable one is automatically
selected
and
handed over to the operating personnel. The next pane is then placed
on top, accurately aligned,
and the sandwich is
assembled. By pressing a key,
the operator releases the sandwich so that
it moves
over to the pre-nip. As
the assembly zone is protected by rotoscanner, the transfer
unit
can be
requested by only one person.
