Additional Blower
An additional single blower (1) (optional)
stabilizes the air cushion near the leading
edge of the floating sheet. This is especial-
ly useful for long and narrow sheets.
The single blower (1) is positioned next
to the front stop (2), while the stop plate
(3) which comes with each single blower
is pushed onto the rear paper stops.
When the single blower is used, the front
blowers must be made inoperative.
For this purpose detach the hose (4) for
the front blowers from the valve (5) and
connect the air hose (6) of the individual
blower in its place.

Side Blowers
The feeder can also be equipped with side blowers in the place of the rear edge
separator (see separate mounting instructions).
By supplying air to the side and rear edge of the stack, the topmost sheets are detached
so that separation through the suction drum is possible. Contrary to operation with the
rear edge separator, the topmost sheet is not lifted.
The air nozzles (7) are attached
to cross-bars at the side (8) and
the rear (9) of the paper stack.
For replenishing paper, the two
cross-bars can be raised to
provide access to the pile table.
After the replenishing process
the bars are returned to the
working position.
